Top 6 Venomous Snakes in Bali: Essential Safety Tips

There are six distinct species of hazardous and venomous snakes in Bali, as well as numerous non-venomous varieties that inhabit this well-known tourism destination in Indonesia.

However, concerns regarding snakes should not detract from your vacation in Bali. Incidents involving snakes are infrequent in touristic areas of the island, and these creatures typically exhibit a shy demeanor, opting to retreat before conflict unless harmed or provoked. In fact, they generally prefer to evade human interaction altogether.

Having resided in Bali for several years and traversed various regions of the island (including many off-the-beaten-path locations), my wife and I have only encountered one or two snakes during our time here. The photographs included in this guide were captured with assistance from a professional snake catcher in Bali.

Though the likelihood of tourists or temporary visitors encountering a snake in Bali is low, it is advisable to familiarize yourself with the venomous species present and the appropriate actions to take should you come across one.

This guide aims to clarify how to recognize the dangerous snake species in Bali, the protocol if you discover a snake at your lodging (or in rice paddies), who to contact for snake removal, and what steps to take if bitten by a snake in Bali.

Where To Stay In Bali

How To Avoid Bali Snakes

To begin with, here are some guidelines to assist you in avoiding snakes in Bali and ensuring your safety:

• Exercise respect for all snakes in Bali, treating them as venomous. It is best to leave them undisturbed and refrain from touching them.
• Avoid attempting to capture or eliminate snakes. Seek assistance from a professional. Contacts for snake catchers have been provided later in this article.
• Always carry a reliable light source when walking at night to clearly see the path. Stepping on a snake in the dark is to be avoided.
• While hiking or navigating through dense vegetation, proceed slowly and make noise to alert snakes to your presence. Most snakes in Bali will retreat upon hearing a person approach.
• It is advisable to wear long pants and closed-toe shoes when trekking in jungle areas, as most snake bites occur on extremities.
• For identification purposes, capture photographs of any observed snake from a distance of at least 2 meters (7 feet).
• Opt for enclosed bathrooms in Bali over open designs if you wish to minimize the chances of encountering snakes and other intruders.

6 Dangerous / Venomous Snakes Of Bali

• Island Pit Viper (Trimeresurus Insularis)

The Island Pit Viper stands as one of the most frequently observed venomous species in Bali, having been responsible for several bites and fatalities in both Bali and Java. It can be found throughout all rural regions of Bali.

This snake is notable for its triangular head and vibrant green body, complemented by a reddish-brown tail. The tail coloration and head shape serve as the most distinguishing features when identifying this species compared to similarly appearing non-venomous green snakes.

It is regarded as a beautiful species, with eye-catching color variations such as bright turquoise or banana yellow occasionally observed in areas such as the Komodo Islands in Indonesia.

The green hue of the Island Pit Viper allows it to blend seamlessly into the foliage of tropical jungles, where it typically conceals itself during daytime hours, descending to hunt at dusk.

Island Pit Viper in Bali. VENOMOUS!

On one occasion, I nearly trod on an Island Pit Viper while hiking in Nusa Penida Island, in a less traversed region rich in vegetation (this was not in a heavily touristic area).

My foot came alarmingly close to the snake, which was coiled in the path, but fortunately its head was turned away from me, allowing it to remain oblivious to my proximity.

This experience was quite close. I stepped back to observe the snake for a moment, and it eventually slithered away into the trees.

Bites from the Island Pit Viper can lead to significant tissue swelling and necrosis, internal hemorrhaging, and potential fatalities. There is no available anti-venom for this species in Bali, and individuals who survive bites may require limb amputations.

This snake has a proclivity for arboreal habitats within tropical rainforests but can also inhabit various other environments. Its diet primarily consists of rodents, lizards, birds, and amphibians, and adults typically reach lengths of about 1/2 meter (1.5 feet).

In local terminology, this snake is referred to as ‘Ular Hijau’ (Indonesian) or ‘Lipi Gadang’ (Balinese), the latter meaning ‘green snake.’ Approach this species with utmost caution!

• King Cobra (Ophiophagus Hannah)

The King Cobra is recognized as the largest venomous snake globally, attaining lengths of up to 4 meters (13 feet) or more. It is predominantly found in rural regions of western Bali, specifically in the provinces of Jembrana, Buleleng, and Tabanan.

When threatened, the King Cobra expands its hood and can elevate a third of its body off the ground, reaching a height comparable to that of an adult.

This snake features an olive/brown body adorned with pale diagonal stripes, and its hood is narrow, showcasing yellow or cream-colored patterns on the interior.

The King Cobra exhibits intelligence and typically refrains from biting unless it feels imperiled or injured. This species is characterized by its fearless demeanor but generally prefers to vacate the area rather than engage in confrontation.

Bites from the King Cobra can rapidly induce paralysis of muscles, respiratory failure, and ultimately death. A single bite can deliver enough venom to potentially kill 20 individuals, and there is no anti-venom accessible for it in Bali.

This snake is mainly diurnal, primarily preying on other snakes, and exhibits cannibalistic behavior as well.

Locally, it is known as ‘Ular King Kobra’ (Indonesian) or ‘Lipi Selem Bebek’ (Balinese). Always exercise extreme caution when encountering this species!

• Javan Spitting Cobra (Naja Sputatrix)

The Javan spitting cobra is considerably smaller than the King Cobra, typically reaching lengths of approximately 1.3 meters (4 feet) or less. This cobra species is present in all rural areas of Bali.

Similar to the King Cobra, the Javan spitting cobra also extends its hood when threatened. However, when its hood is closed, it closely resembles non-venomous snakes in Bali due to its plain brown and beige coloration.

This species possesses a highly venomous bite and is capable of spitting venom at distances of up to 2 meters (7 feet). If venom comes into contact with the eyes, it can cause excruciating pain, swelling, and in severe cases, blindness. If the venom reaches the eyes of either yourself or a pet, irrigate the eyes with running water for 30 minutes. Avoid rubbing the eyes, as this may exacerbate the situation!

Bites from the Javan spitting cobra can lead to tissue necrosis, muscle paralysis, respiratory failure, and death. Fortunately, anti-venom is available at select hospitals in Bali.

This snake may be active both during the day and at night, with a primary diet consisting of rodents, amphibians, lizards, and other snakes.

The local names for this species include ‘Ular Sendok’ (Indonesian) and ‘Lipi Sendok’ (Balinese), with the latter meaning ‘spoon snake,’ referencing the shape of its hood.

Like other venomous snakes in Bali, treat this species with extreme caution!

• Malayan Krait (Bungarus Candidus)

The Malayan Krait is among the most venomous snakes found in Bali, at times misidentified as non-venomous species due to its plain dark coloration. This snake occupies several rural areas of Bali.

In Bali, this snake may appear entirely black, displaying no stripes, though more commonly, it has alternating black and white stripes, reaching lengths around 1 meter (3 feet) or less. It is predominantly nocturnal, often venturing into human dwellings.

Bites from the Malayan Krait can result in muscle paralysis, respiratory failure, and potentially death. Left untreated, such bites are often fatal. No anti-venom exists for this species in Bali, but survival is a possibility with ventilator-assisted breathing.

The Malayan Krait typically exhibits a docile nature and will only bite if provoked. Its diet primarily consists of other snakes, supplemented by small mammals, lizards, and amphibians.

This snake is colloquially known as ‘Ular Weling’ (Indonesian) and ‘Lipi Poleng’ (Balinese), with the latter meaning ‘black and white snake.’ Always exercise extreme caution!

Malayan Krait in Bali. VENOMOUS!

• Banded Sea Krait (Laticauda Colubrina)

Also referred to as the Yellow-Lipped Sea Krait, this is a venomous marine snake that can be observed both on land and in ocean waters. It inhabits coastal regions surrounding Bali.

The Banded Sea Krait is characterized by its yellow snout and evenly distributed black and bluish/grey stripes throughout its body, along with a paddle-shaped tail that enhances its swimming capabilities. Females are generally larger than males, growing up to 2 meters long (6 feet).

This species spends a significant amount of time swimming among coral reefs in shallow waters while it hunts for eels and fish, yet it also surfaces on land for rest and egg-laying, thus potential beach encounters in Bali may occur.

If you encounter one of these marine snakes during snorkeling or diving, maintain a respectful distance. Although they are non-aggressive and reluctant to bite, their neurotoxic venom poses a considerable threat and can be lethal.

In local vernacular, this snake is designated as ‘Ular Laut’ (Indonesian). Exercise extreme caution!

• Reticulated Python (Malayopython Reticulatus)

The Reticulated Python is non-venomous, but may still present a danger. Pythons are found across various rural areas in Bali, and occasionally appear in urban settings, typically as a result of being carried into town by flooding during the rainy season in Indonesia.

While smaller pythons are generally harmless to humans, larger individuals can pose serious risks if they reach a size capable of constriction (suffocation due to squeezing). Adult pythons can grow to lengths ranging from 3 to 9 meters (10 to 30 feet), and it has been reported that pythons in Bali have been captured at lengths up to 5 meters.

In the event someone is being constricted by a large python, the priority is to detach the snake, ideally with the assistance of multiple individuals to ensure safe control. Begin by unwrapping the snake starting from its tail, ensuring one person securely holds the snake’s head to prevent bites.

The Reticulated Python is primarily nocturnal and exhibits impressive swimming and climbing abilities. Its diet includes mammals, lizards, and birds. Locally, this snake is known as ‘Ular Piton’ (Indonesian).

Bites from the Reticulated Python are non-venomous but may lead to infection; hence, updates on tetanus shots and antibiotic treatments are advisable. Caution is warranted for larger pythons in Bali (over 2.5 meters)!

Are There Snakes In Bali Rice Fields?

Yes, encountering snakes in Bali rice fields is possible, although it primarily varies based on the specific region of the island in question.

While a snake sighting may occur at well-known locations like Jatiluwih Rice Fields or Tegalalang Rice Terrace, such occurrences are uncommon, as the snakes would likely be concealed within the rice paddies, avoiding human contact whenever possible. Despite numerous visits over the years, I have never spotted a snake at either site.

On one occasion, I did observe a green snake in a rice paddy near Sanur, but it moved swiftly enough that I could not identify it. Thus, while snakes do inhabit Bali’s rice fields, they generally do not pose a threat to visitors as long as they remain undisturbed.

Maintain awareness of your surroundings while walking, and the likelihood of encountering any of Bali’s snakes will be minimal.

Are There Snakes In Bali Resorts?

Indeed, there is a possibility of encountering snakes within Bali resorts or hotels; however, the overall risk remains low for the majority of tourists.

Reports exist of individuals in the Ubud area discovering snakes (including kraits and cobras) in their gardens, bathrooms, or living areas, and reports of pet dogs being struck in the eyes by spitting cobras have also emerged.

Again, such incidents are relatively rare; nonetheless, they do occur. It is simply part of residing in Bali. Therefore, it is essential to familiarize oneself with the venomous snakes present in the area, just in case.

Fortunately, for those who experience apprehension regarding snakes, accommodations in southern Bali—such as Kuta, Seminyak, and Sanur—are available, where the vast majority of tourists are far less likely to encounter snakes.

Snake Bites & Deaths In Bali

For reference, here are some verified instances of snake bites and fatalities in Bali over the years:

• In 1999, Australian surfer Peter Crawford lost his life due to a snake bite in Bali. Reports suggest that this was caused by an island pit viper, though the exact species remains unconfirmed. (Source: Surfer’s Journal)
• In 2013, an Indonesian security guard at the Hyatt hotel in Sanur was killed by a 5 meter (15 foot) python while attempting to relocate it from the road at night when it constricted around his neck. (Source: Jakarta Post)
• In 2016, a member of the Bali Reptile Rescue initiative was bitten by a king cobra, resulting in his demise at Jembrana Hospital in West Bali. I Putu Agus Edi Darmawan was relocating a mother cobra and her eggs for protection when he suffered a finger bite. He was a respected member of the Bali snake community with 15 years of experience at the time of his passing. (Source: Tribun News)
• In 2017, an Australian woman was bitten after stepping on a brown snake in Ubud. She quickly became severely ill post-bite, vomiting and losing consciousness, but fortunately received anti-venom at an Ubud hospital and survived. (Source: Perth Now)
• In 2019, a 12-year-old Balinese girl from Gianyar passed away after being bitten on the hand by a small black snake while asleep. (Source: Nusa Bali) Additionally, reports indicated that Buleleng Hospital treated 126 snake bites in that year alone, which is a startling statistic if accurate. (Source: Nusa Bali)
• In 2022, two residents from Bali were treated after sustaining snake bites during Nyepi Day at the hospital in Jembrana. (Source: Radar Bali)

These examples represent only a fraction of confirmed snake bite cases and fatalities in Bali. Essentially, this is not an exhaustive record, as most snake bites affecting local Balinese residents seldom receive media attention, let alone translation into English.

I share this information not to instill fear but rather to promote awareness and safety. Despite having lived in Bali for several years, my wife and I typically have little concern regarding snakes. Nonetheless, it remains vital to comprehend the potential risks posed by these creatures if appropriate precautions are not taken.

Where To See Live Snakes In Bali

For an authentic and educational snake experience in Indonesia that directly contributes to conservation efforts, you can participate in a herping tour with Bali Reptile Rescue in West Bali.

Bali Reptile Rescue offers night herping excursions where you can observe various snake species, as well as a two-day king cobra tour. This immersive experience may not be suitable for the faint-hearted, as it involves trekking through jungle terrain and may include encounters with potentially dangerous snakes.

Our experience with BRR while observing the king cobra was remarkable, allowing us to experience this majestic creature in its natural environment. I personally find the King Cobra to be one of the most fascinating snakes found in Bali.

Moreover, the revenue generated from such tours contributes to land and waterway conservation and education initiatives concerning snake populations in Bali. BRR frequently relocates snakes from human dwellings and releases them back into their natural habitats, preventing the likely euthanization of many of these creatures without their intervention.

It was awe-inspiring to witness this King Cobra in Bali, Indonesia.

If observing snakes in captivity is preferable, a highly recommended location is the Bali Reptile Park, situated in Gianyar (near Ubud), which features a diverse selection of vipers, boas, cobras, and pythons displayed in glass enclosures.

Within the safety of glass barriers at the reptile park, visitors can safely observe all the dangerous snake species indigenous to Bali, along with selected species from Indonesia, Southeast Asia, and beyond.

It is also feasible to view several types of live pythons at the Bali Zoo or Bali Safari Marine Park, although there is less variety compared to the reptile park.

Is There A Bali Snake Temple?

The numerous Hindu temples in Bali encompass a bat temple, a fire temple, a car temple, multiple monkey forests, and an ‘elephant cave,’ yet there is no specific temple devoted entirely to snakes.

Nevertheless, a couple of locations may closely resemble a Bali snake temple. The Tanah Lot temple, located on the southwestern coast of Bali, is believed to be safeguarded from malevolent spirits and intruders by venomous sea snakes present in the surrounding waters.

Additionally, there exists a cave near Tanah Lot featuring a ‘holy snake’ for which visitors can pay a small fee to observe. This is a black and white ringed sea snake (reportedly a highly venomous Banded Sea Krait).

A palace situated near Ubud, known as Puri Langon, features two large stone cobra sculptures with their hoods raised. While no live snakes can be found there, the intricate carvings and details within the palace are noteworthy. It serves as a popular venue for traditional Balinese pre-wedding photography sessions.

Handcrafted wooden cobras have also long served as a popular and entertaining souvenir for visitors to Bali, readily available at street stalls throughout the island.
