Discover 25 Must-See Hidden Gems in Hawaii

As the final state to join the United States, Hawaii became part of the Union in August 1959. Its admission was preceded by Alaska, which joined in January of the same year. The previous state to join, Arizona, did so nearly 50 years prior.

The only state composed entirely of islands, Hawaii is located in the northeast quadrant of Polynesia, situated at the heart of the North Pacific Ocean.

This volcanic archipelago consists of hundreds of islands and islets, encompassing both large and small. Six main islands are accessible for tourism. Notably, these islands are the summits of underwater mountains, part of the most extensive mountain range on the planet.

The state is celebrated for its picturesque landscapes, intriguing environments, distinctive culture, myriad outdoor activities, and a laid-back lifestyle. It is indeed a location that provides a unique experience for nearly every type of traveler.

The cultural milieu of Hawaii is shaped by Polynesian traditions alongside influences from Asia and North America. The cuisine encapsulates the diverse cultures that have left their mark on the islands, blending native dishes with elements from various regions including Polynesia, the USA, Japan, China, Korea, the Philippines, and Portugal.

As the only U.S. state to cultivate coffee, Hawaii is also responsible for approximately one-third of the world’s commercially grown pineapples. Additionally, Hawaii leads in macadamia nut production. The state boasts the only royal palace in the nation, the largest wind generator, the most extensive telescope, the largest dormant volcano, the most active volcano globally, and some of the best scuba diving locations worldwide.

While Hawaii’s stunning beaches, lively cities, volcanoes, and lush rainforests attract numerous visitors, resulting in crowded experiences, there remain many areas where one can escape the masses and discover serene retreats.

Below are some of Hawaii’s finest hidden treasures.

1. Bamboo Forest, Maui

A captivating location reminiscent of a fairytale, Maui’s stunning Bamboo Forest can be accessed via the scenic Pipiwai Trail within Haleakala National Park. Although it requires a mile-long trek to reach, many visitors are hesitant to undertake the effort. Those who do, however, are rewarded with breathtaking views.

The sunlight filters through the towering bamboo stalks, which create ample shade and ambiance. The forest extends for approximately half a mile, with birds chirping and insects buzzing all around.

Additionally, several lovely features grace the trail leading to the picturesque forest, including a magnificent waterfall. Please note that swimming is not advised at either the top of the falls or in the pool at the bottom due to safety concerns. The splendid scene is best appreciated visually.

Be sure to wear sturdy closed footwear and apply plenty of insect repellent. Bring sufficient water for your hike.

2. Kawela Bay, Oahu

A serene and sheltered beach, Kawela Bay is located near the northern tip of Oahu. A natural reef breaks larger waves from reaching the sandy shore, making it an ideal venue to reconnect with nature and enjoy a tranquil stretch of sand away from large crowds.

Despite previous plans for development in the area, Kawela Bay remains blissfully undeveloped, safeguarded by the North Shore Community Land Trust in accordance with local aspirations. This preservation allows visitors to experience a slice of paradise with very few amenities.

Unique banyan trees lend an air of intrigue to the area.

Enjoy swimming in the calm, crystalline waters, attempt paddle boarding, kayak along the shore, relax on the beach, or indulge in a picnic amidst idyllic surroundings.

If you experience a sense of déjà vu while here, it may be attributed to the beach’s appearances in various films, including *Pirates of the Caribbean* and *The Hunger Games*.

3. Kalalau Trail, Kauai

Rugged, challenging, remote, and extraordinarily beautiful, the 11-mile-long Kalalau Trail follows the stunning Na Pali Coast on the island of Kauai. Certain sections of the trail require a permit for access, and it is advisable to explore the area with a local guide.

Camping is permitted only in two designated locations, equipped with basic facilities such as composting toilets, but lacking potable water and seating areas.

The trail traverses five pristine valleys—each equally appealing yet distinct. The lush, velvet hills possess a soft appearance which contrasts sharply with their steep inclines leading to the crashing waves below. Walking atop towering cliffs provides some of the most remarkable vistas of the ocean.

Along the exhilarating trail, you will discover several stunning waterfalls and spectacular beaches, including the relatively secluded Kalalau Beach, also intriguingly referred to as the Secret Beach. Although the trail poses both physical and emotional challenges, plenty of areas exist where you can repose in quiet contemplation, embracing the natural beauty around you.

4. Sanju Pagoda, Oahu

Nestled within Honolulu Memorial Park on Oahu, the impressive Sanju Pagoda is a sizable replica of a revered temple in Japan, specifically the Minami Hoke-ji Temple located in Nara. Standing at 119 feet in height, this magnificent structure commands attention. Despite its size, it remains relatively under-visited.

Exhibiting exquisite Japanese architectural designs, the three-tiered pagoda is constructed from concrete as opposed to traditional wood. It is recognized on the National Register of Historic Places.

Often regarded as one of the tallest temples in the United States, if not globally, the edifice dates back to 1966. Unfortunately, due to financial strife affecting the park, it fell into disarray and has since become unsafe; thus, it is currently closed to public access, although one can still admire its grandeur from the outside.

5. Raëlian UFO Peace Park, Big Island

Strange and intriguing, the Raëlian UFO Peace Park is situated next to a highway and might provoke contemplation about the nature of existence. Alternatively, it could prompt curiosity regarding the figures who conceptualized Raëlianism.

Raëlianism is an alternative religious movement, occasionally categorized as a cult, originating in the 1970s. Founded by Claude Vorilhon—commonly referred to as Raël—this belief system posits that life on Earth originates from an extraterrestrial species known as Elohim. Controversially, adherents maintain that prophets of significant world religions were manifestations of the Elohim, appearing throughout history to communicate with the general populace.

The group aims to establish a galactic embassy on Hawaii’s Big Island, following unsuccessful attempts in Israel. At present, only a model of the proposed embassy exists, ostensibly geared to welcome alien life forms to Earth, surrounded by several intriguing statues.

While these unusual structures may capture the fleeting curiosity of passersby, many casual visitors remain unaware of the site’s significance without further inspection.

6. Keahiakawelo, Lanai

Also known as the Garden of the Gods, Keahiakawelo features a series of natural rock formations on the island of Lanai. Do not be concerned if the road leading to this enchanting site is riddled with bumps and potholes; the journey truly feels like heading into the depths of nowhere!

This otherwise barren landscape becomes oddly captivating due to the unique rock formations present. The reddish dry soil is scattered with boulders of various shapes and sizes, and visitors may observe that previous guests have arranged the stones in small towers or designed structures. However, local legends warn that disturbing the stones may invoke the anger of ancient deities—consider yourself forewarned!

According to stories, two wise men from Molokai and Lanai were engaged in a competition to see who could sustain a fire the longest. The resulting ethereal landscape on Lanai supposedly reflects the efforts of local sages to clinch the contest.

7. Harold L. Lyon Arboretum, Oahu

Named in tribute to a former director of the Hawaii Sugar Planters’ Association and an expert in plant disease studies, the Harold L. Lyon Arboretum often remains uncrowded. Many visitors to the local area focus solely on the nearby Manoa Falls, neglecting to spare time for this lush and fertile garden.

Educational, scenic, and informative, the site hosts 12 well-manicured gardens. A vast collection of tropical flora is cultivated here, alongside numerous walking trails that span a total of seven miles. One principal trail leads to the tranquil Aihualama Falls, offering a splendid opportunity to admire Mother Nature’s creations without the crowds.

Among the diverse plant species are several rare and endangered varieties endemic to Hawaii. It serves as an excellent destination for botany enthusiasts who seek to depart from the well-trodden tourist paths for a few hours.

8. Glass Beach, Kauai

Located in a predominantly industrial area of Eleele on Kauai, Glass Beach may not initially strike visitors as a prime destination during their Hawaiian getaway. Nonetheless, this unusual beach is well deserving of a brief detour.

Though it is not suitable for traditional sunbathing or walking barefoot, Glass Beach offers something entirely unique. While it may not present the most picturesque shoreline, the sight of smooth and rounded pieces of multi-colored glass strewn across the volcanic rocks is undeniably visually striking.

Years of discarded glass have accumulated and subsequently washed ashore, resulting from broken bottles and other glass items. The sharp edges have been smoothed by relentless natural forces. While many hazardous edges have been eroded, it is prudent to remain cautious of any remaining sharp pieces.

9. Kaumana Lava Tubes, Big Island

Situated on the Big Island, near Hilo, the intriguing Kaumana Lava Tubes remains relatively obscure. Delve into these interesting tunnels to appreciate the stunning aspects of nature while escaping the throngs of tourists found in more popular areas of the island.

More authentic and unrefined than other commercialized lava tubes on the Big Island, the Kaumana Lava Tubes extend beneath the ground, formed by the forceful flow of molten lava during volcanic eruptions. The scientific principle here is that hot lava flows beneath a solidified outer layer, eventually exiting and leaving behind a hardened tubular structure. When part of the ceiling collapses, it creates an entrance for exploration, as is the case at Kaumana.

There are no guards or guides present, allowing you the freedom to explore any time without interruption while also necessitating personal responsibility for your safety. A flashlight is essential for navigating deeper into the caverns, as the rocks can be jagged and slippery; exercise caution!

10. Coco Palms Resort, Kauai

Located at the base of Nounou Mountain, popularly known as the Sleeping Giant, the small town of Kapaa is well-prepared for visitors, featuring numerous hotels, dining establishments, and shops. However, it is also home to a dilapidated and abandoned resort that has dramatically deteriorated from its former glory.

Coco Palms Resort was the first resort established on the island, opening its doors in the 1950s and attracting illustrious personalities like Elvis Presley and Frank Sinatra. The opulent and pricey resort was a coveted retreat for the affluent. Unfortunately, the revelry ended abruptly in 1992 due to a catastrophic hurricane that ravaged the region.

Hurricane Iniki was a formidable force, leaving destruction in its wake. Insurance companies faced bankruptcy, and the local economy was devastated.

Even as the community healed from the financial, physical, and emotional damage, Coco Palms Resort was never restored. Its condition has only worsened over time. Although there are plans to demolish the remnants, disagreements over land ownership have prevented its removal.

11. Hawaii Volcano Treehouse Rental, Big Island

An appealing lodging option, the Hawaii Volcano Treehouse Rental is situated near Hawaii Volcanoes National Park on the Big Island. This offers an opportunity to immerse in nature and experience a unique accommodation experience, which is likely to captivate both young and older guests.

Rustic, inviting, and environmentally conscious, these treehouses are built from wood and perched high in the trees, flanked by branches while providing wonderful views through every window. They are ideal for romantic getaways, adventurous solo retreats, family vacations to remember, or an escape with friends.

Constructed among several sturdy trees and elevated 20 feet above ground, they may not be suitable for those with a fear of heights. However, for those comfortable with heights, the canopy skywalk provides additional breathtaking views of the surrounding nature.

Each treehouse is equipped with a private bathroom, wooden furnishings, comfortable beds, ample storage space, and dedicated seating areas. They surely inspire awe and wonder.

12. Niihau, Niihau

The private island of Niihau spans nearly 70 square miles, making it the seventh-largest inhabited island in the archipelago. Estimates of its population vary significantly; some sources suggest that as many as 300 individuals reside here, while others place the figure as low as 30-40. Regardless, interaction with the local inhabitants is not feasible for visitors.

The island features a school, a church, and rent-free private residences; however, it is devoid of electricity apart from solar power and lacks running water since the local water supply relies on rain catchments. During periods of water scarcity, residents must temporarily relocate to another island until the rains return. Grocery supplies arrive via regular barge service, and meat is provided at no cost for locals.

As such, there are no Wi-Fi services, and television signal reception is poor. Conjuring images of a bygone era, the island strives to preserve age-old Hawaiian traditions and ways of life.

Acquired in 1864, prior to the island’s annexation by the United States, Niihau is presently owned by the Robinson family. Those familiar with Daniel Defoe’s classic novel *Robinson Crusoe* or Johann David Wyss’s *Swiss Family Robinson* might find the name particularly fitting.

Frequently referred to as the Forbidden Island, access for outsiders is restricted to exceptional circumstances. As a result, Niihau remains a true hidden gem, likely to maintain its exclusivity for the foreseeable future. Interested tourists can admire the island from a helicopter tour.

Alternately, those who are particularly eager to visit Niihau may participate in a beach tour or hunting expedition, although direct visits to the community are prohibited.

13. Kukaniloko Birthing Stones, Oahu

Located near Wahiawa on the island of Oahu, Kukaniloko Birthing Stones is often overlooked by passing motorists who may not appreciate the site’s significance and historical value.

What appears to be a random assortment of stones may, at first glance, seem to be either a natural arrangement or one imposed by human intervention. Regardless of your interpretation, it is worthwhile to pause, explore, and uncover the stories that these stones hold.

The Kukaniloko Birthing Stones are significant as they represent sites of royal births and prominent battles. Indigenous people believed this location was endowed with natural energies. Pregnant women were transported here to give birth under the watchful eyes of powerful chieftains, with infants being separated from their mothers until they matured into adulthood.

A sacred space for islanders, it is also speculated that the site held astronomical significance in addition to its ritualistic role.

14. Dunes, Kauai

Near Koloa, nestled within the cliffs, one will discover a prehistoric landscape replete with unusual stone-like sand dunes. Indeed, you read that correctly—dunes composed of stone.

This prompts the question: are they sand or rock? The answer lies in their formation: these dunes were once composed of sand that underwent a process called lithification over time. In simple terms, sand is compacted under pressure, loses its porosity, and ultimately converts into stone.

The once-sandy, now-stone formations maintain a vibrant hue, providing a stunning visual contrast against the azure waters of the sea. The landscape exudes an ancient and extraordinary quality.

A relatively easy walk leads visitors to this area, tracing the summit of the cliffs. Accessing the site, however, necessitates a robust 4WD vehicle.

15. Waimanu Valley, Big Island

The magnificent Waimanu Valley marks the largest valley along the Hamakua Coast. Although the trek to access the valley can be arduous, the incentive awaiting you is immense. Those who complete the nine-mile journey are rewarded with breathtaking views and a profound sense of accomplishment.

The path follows the steep Muliwai Trail through the picturesque Waipiʻo Valley, navigating past numerous streams and waterfalls. It is worth noting that the trail involves considerable elevation changes and can be slippery; trekking poles may prove invaluable. Furthermore, plan to carry all necessary supplies, including camping gear, as pre-arranged camping sites are mandatory.

This enchanting hidden valley offers tranquility, recreation, and revitalization for the mind, body, and soul. With its black sandy beaches, it serves as an ideal location to bask in the sun, while the crystalline (and brisk) waters invite a refreshing swim. With the ocean on one side and lush landscapes on the other, the views are unparalleled.

For those willing to hike a bit further, several nearby waterfalls await exploration.

16. Makauwahi Cave, Kauai

Integrating archeology, natural wonders, and history, the Makauwahi Cave is one of the most substantial caves on the island of Kauai, yet remains significantly under-visited. This site is replete with captivating fossils, offering an entrancing glimpse into the past.

Similar to an ancient chronicle, the cave’s layers vividly illustrate the region’s geological history. A fossilized sand dune collapse resulted in the creation of a sinkhole that is now accessible for exploration.

Marvel at the fossilized remains of various species and plants that existed long before human arrival. For geology enthusiasts, this location is an extraordinary opportunity.

Do not let the cave’s narrow and potentially claustrophobic entrance deter you; it swiftly expands into a spacious cavern. Explore freely and afterward visit the nearby turtle sanctuary for further amniotic encounters. Be sure to admire Mahaulepu Beach prior to your departure, as it was a filming location for *Pirates of the Caribbean*.

17. Ching’s Pond, Maui

Commonly referred to as the Blue Sapphire Pools, Ching’s Pond is not visible from the road, indicating that those unaware of its existence may easily pass by without realizing the nearby beauty. The site is, however, a popular locale among locals; once witnessed, its appeal becomes apparent. Weekends may see an influx of visitors, but visits during the week tend to be quieter.

The Palauhulu Stream flows across the rocks, spanned by a bridge. Look beneath the bridge to behold some of the most mesmerizing deep sapphire-blue pools; their beauty may prompt you to blink in disbelief.

Two trails lead to the pools, although one is considerably more challenging and is not recommended. Seek a large tree situated approximately 50 feet beyond the bridge; this trail is the most advisable route to follow.

It is easy to envision fairies, nymphs, and other mythological beings residing in these waters. Venturing into the water may yield an ethereal experience, yet exercise caution, as the current can be deceptively swift, potentially sweeping you away.

Rocks litter the water’s surface, making it an unsuitable site for diving. Although some individuals may be seen diving from elevated locations nearby, to preserve the integrity of your vacation, it is prudent to resist the temptation.

18. Kau Desert, Big Island

Vast, resembling a lunar landscape, and arid: these descriptors aptly encapsulate the Kau Desert on Hawaii’s Big Island. This seldom-visited region features sand, volcanic ash, gravel, massive rocks, and solidified lava formations, with very little wildlife able to thrive amid the desolation of the landscape.

It is not solely the arid environment and harsh terrain that inhibit growth here; rainfall that does occur is typically too acidic to support life. Sulphur dioxide emissions from volcanic vents mix with moisture in the atmosphere, resulting in toxic precipitation.

This area resembles a locale forgotten by time; the unusual vistas are striking in their rugged, raw, and dramatic appearances. Visitors should be aware that temperatures can soar; it is wise to carry ample water, apply sunscreen, wear loose-fitting clothing, and don a hat.

Avid hikers and trekkers, particularly those enthusiastic about exploring unconventional destinations, will undoubtedly appreciate this locale. It is important to note that some trails may be closed during periods of heightened volcanic activity, as one would prefer to avoid exposure to noxious gases emitted.

19. The Vintage Cave Club, Oahu

Upscale, stylish, exclusive, and luxurious, the Vintage Cave Club is regarded as one of the most high-end (and costly) restaurants on Oahu, if not throughout Hawaii. While it may not be classified as a hidden gem per se, its prestigious price point deters many patrons.

If fortune smiles upon you or you feel compelled to indulge, the Vintage Cave Club delivers an unparalleled dining experience.

The dimly lit dining area, with bare brick walls, is adorned with world-class artwork from renowned artists including Picasso, Zhou Ling, Anton Molnar, and Leonard Tsuguharu Foujita. Exquisite glassworks and ceramics further amplify the ambiance of grandeur and sophistication.

The wine cellar is stocked with a wide variety of fine wines catering to diverse palates and preferences. Additionally, an array of vintage whiskies, cognacs, and brandies are available. The Japanese-French fusion cuisine promises an explosive blend of flavors as the inventive chef utilizes fresh, local produce to create imaginative dishes.

20. Lanai Cat Sanctuary, Lanai

Home to approximately 500 cats, the Lanai Cat Sanctuary serves as a haven for cat enthusiasts. This sanctuary spans 25,000 square feet and provides a refuge for previously stray cats.

The remote island previously faced overwhelming populations of feral cats, necessitating drastic measures that led to inhumane culling of the animals. The sanctuary was established as a response to protect and rescue these animals, offering them a safe environment to live, play, and thrive.

In addition to safeguarding cats, the sanctuary aids in the preservation of the ua’u bird, as feral cats had been predating the native bird population. Neuter-and-release initiatives helped manage cat populations, but these efforts fell short of protecting the birds. Thus, in 2009, the sanctuary opened its doors—benefiting all parties involved!

Cat-loving visitors can now explore the sanctuary, engage with the cats, learn about its initiatives, and, of course, graciously contribute a donation.

21. Pineapple Garden Maze, Oahu

Located within the grounds of the Dole Pineapple Plantation, the Pineapple Garden Maze boasts the distinction of being the world’s largest plant maze.

Spanning two acres, the maze contains approximately two and a half miles of pathways. Naturally, some paths lead to dead ends, while others are strategically designed to challenge and perplex participants.

Several exits exist, so there is no need to fear becoming ensnared indefinitely!

Housing around 14,000 plants, visitors can appreciate the array of scents and sights while navigating their way to freedom. Those who swiftly conquer the maze will be honored with their name inscribed on a sign adjacent to the maze—a fun challenge with an average journey duration of about an hour.

22. The Himalayan Academy, Kauai

Upon visiting the Hindu Himalayan Academy, you may feel as though you have been transported to Nepal, Tibet, or another distant locale. Rather than the rugged terrain typical of the actual Himalayan landscape, you will encounter tropical surroundings instead.

This site effectively marries Eastern religions with Polynesian customs and modern lifestyles, serving as a sanctuary where tradition meets contemporary practices. The tranquil monastery was founded by Satguru Sivaya Subramuniyaswami.

As a global outreach and educational center for Hinduism, the academy adheres to the ancient teachings of gurus from Sri Lanka and southern India.

Surrounded by majestic cliffs, cascading waterfalls, lush rainforests, and expansive blue ocean, the monastery and temple offer an ideal environment for spiritual worship and the pursuit of inner peace. The architectural design of the temple itself is quite remarkable.

Monks don traditional handcrafted robes, enjoy nourishing meals sourced from their own land, and dedicate themselves to a higher purpose while gaining access to modern technology, including smartphones and laptops.

23. Shangri La, Oahu

Transitioning from Hinduism to Islam, Shangri La serves as a concealed assemblage of stunning Islamic art. Situated in proximity to Honolulu, this collection was initiated by the affluent philanthropist Doris Duke.

Shangri La was originally Duke’s Hawaiian retreat, designed according to her own vision, heavily influenced by her global travels. Her fascination with the Middle East is evident throughout the architectural elements.

The residence houses a plethora of exquisite artworks, collected by Duke over the years from various global destinations. Notable pieces include intricate wooden carvings from Morocco, vibrant tile work from Iran, and embellished textiles from Central Asia. A selection of paintings and sculptures, including commissions from notable artists within the Islamic art community, adorn its walls.

Named after a legendary lost paradise, Shangri La is set within extensive grounds that overlook the swirling ocean. Notably, the estate features a large saltwater swimming pool and an Iranian-style pavilion.

24. The Blue Room, Kauai

Another remarkable location in Hawaii, the unique Blue Room is an extraordinary cave that leads into a captivating wet subterranean world.

While visitors will pass by two other caves during their hike, none can adequately prepare them for the awe-inspiring wonders awaiting within the Blue Room. Also referred to as the Waikapalae wet cave, it features a concealed interior cavern that sparkles in a brilliant deep blue hue when water levels rise.

Although these mesmerizing sights might tempt visitors to take a dip, caution is advised as entering the water is discouraged due to potential health risks. Specifically, avoid submerging if you have open wounds and refrain from ingesting the water. Instead, seek the nearby Ke’e Beach, which is only a short walk away, for a safer swimming option.

If you possess diving experience, this cave could offer intriguing scuba opportunities.

25. The Liljestrand House, Oahu

A historic residence located on Oahu, the Liljestrand House was constructed over half a century ago as a testament to the work of prominent American-Russian architect Vladimir Ossipoff. It provides a glimpse into mid-20th-century Hawaiian design trends.

Mr. and Mrs. Liljestrand were a mixed American-Chinese couple who arrived in Hawaii during the late 1930s, initially planning to head to China. However, political unrest prompted them to remain in Hawaii until stability returned to Mr. Liljestrand’s homeland. Their journey ultimately led them to discover their ideal land on which to construct their home.

An unexpected encounter while hiking through the undeveloped Tantalus Hills facilitated their agreement on the plot where their residence would be built. Their exacting standards during construction ensured that the home matched their envisioned layout.

Now enrolled on the National Register of Historic Places, the house remains in the custody of the couple’s descendants. They pride themselves on their family heritage and are typically accommodating, often allowing visitors to explore the stylish space upon request.

Although delving into Hawaii’s hidden treasures often necessitates considerable effort, such as enduring demanding hikes and prior arrangements, the endeavor is undoubtedly rewarding when one uncovers the unique aspects of this beautiful island state.
