If you’re thinking about paying Bali a visit and want to look into their lineup of wild animals, here’s a helpful guide to assist you in navigating their natural habitat and have an idea of what the dangerous animals in Indonesia are!
Bali animals: The Most Dangerous Animals In Bali
Bali, Indonesia. An exotic island abundant in tropical nature, incredible Bali animals, and amazing weather. So much so that we decided to quit full-time travel with kids, and move to Bali from the UK with our three young children.
If you are heading to Bali grab an essential Lonely Planet pocket guide to Bali– we loved the Lonely Planet guides when we were traveling as they were pretty up-to-date and answered questions we hadn’t even thought of!
See the rest of my Bali blog posts, including the best things to do and where to avoid, here in our huge Bali blog post section. If you’re parents, you’ll probably also like our section on homeschooling blogs (including how we ‘world-schooled’ around Asia) too.

I would strongly recommend anyone thinking of visiting Bali with kids to also check out our top-rated travel toys and our guide to avoiding Zika while in Bali.
You can also see we recommend travel strollers, travel irons, and travel kettles. There are many reasons to visit Bali, amazing things to do in Bali, and great Balinese food. The less-great bits include Bali scams to avoid and Bali earthquakes.
Hopefully, on your trip, you won’t come across many issues and will have a great time without crossing paths with the most dangerous animals in Bali.
Does Bali have poisonous animals? Here are 8 creatures to keep in mind:
What Dangerous Animals Live In Bali?
Bali Mosquitoes
The most dangerous animals in Bali can’t be narrowed down to one species. For a few, it will be a grumpy Komodo dragon that they got too close to.
For many people, it’s the mosquitoes that can transmit dengue fever and Zika, and because of their prevalence, they are probably the animal that poses the biggest risk to tourists.
The NHS Indonesian travel health website is a great resource if you are concerned about your health while you travel. If you are wondering “Do I need malaria tablets for Bali?” the answer is no, but you will need them if you travel to some of the nearby Indonesian islands such as Lombok.
We recommend taking precautions to avoid being bitten (especially if you have kids) such as wearing light long-sleeved tops and light loose trousers. You should also avoid stagnant or slow-flowing water sources and stay in during the evening.
When it comes to mosquito repellant, here is the best mosquito repellant for adults and mosquito repellant for kids (my kids loved the bracelets!) that we used on our travels- these were much better than the sprays, for us and the environment while still being effective.
Check out our post on 11 ways to avoid the Zika virus here if you weren’t already motivated enough to prevent bites- take it from someone who lived in Bali and get that repellant!
Mozzie repellant won’t take care of the next dangerous Bali animal though- this is the one that affected our family the most.

Bali Dogs
The next most common potentially dangerous animal in Bali is dogs, both domestic and stray. We have had four nasty experiences with dogs since we set off from the UK, including three bites, both from ‘domestic’ dogs.
The majority of pet dogs in Bali are not trained to be sociable, they are used as guard dogs for homes and businesses, and as such many are pretty hostile.
Many are also allowed to roam the streets so you are likely to come into contact with dogs on your trip. There are also lots of stray dogs.
These may look cute but are often afraid and neglected or abused and potentially carrying diseases including rabies so we do not recommend touching them.
Bali often has a shortage of the medicine that you need immediately after being bitten by a rabies-infected animal so please exercise extreme caution around these animals. Even a friendly over-excited nip is potentially dangerous.
Carrying an open bottle of water is the deterrent that we found worked the best for protection against stray dogs, as they don’t like being sprayed with water.
While traveling we used and recommend the Chilly water bottles but for a dog, protection gets a single-use plastic bottle as you can squeeze it to squirt water from a distance. Carrying sticks is inadvisable as this can be seen as a threat or a signal to play.
If you are wondering “Do I need vaccinations to go to Bali?” the answer is yes, and we got rabies jabs as well as the standard travel vaccinations.
Bali often has a shortage of the medication you need immediately after a bite so you must be vaccinated to give yourself extra time to get the treatment, in case you have to fly to Singapore.
Our daughter had a brain injury in Bali and the healthcare was awful so I am 100% serious in saying that you need to take every possible precaution to prevent injury or illness while you are on the island. It is very easy to think ‘oh I’ll just go to Singapore if I need something” but we were stuck in earthquakes and unable to fly due to the nature of her injury so that may not be possible.
Bali Jellyfish
There are often jellyfish in the waters around Bali but these are usually just a bit painful and not dangerous. I got stung while trying to signal to my Mum that there was one next to her while snorkeling in Nusa Penida; it was a tiny little guy but it left a sting and a rash.
It was no big deal, a bit like stinging nettle, but a bigger one could hurt (advice is to pee on it to neutralize the sting; you make your own choice!)
These are traveled not the most dangerous animal in Bali to worry about; occasionally there will be a group of poisonous jellyfish such as the purple jellyfish.
Ask locals before you swim and check the local news for jellyfish warnings if you are worried. Wearing a rash guard will help to prevent stings if you can deal with being covered up in the hot weather!

Bali Sea Snakes
Bali is home to plenty of sea snakes, including venomous sea snakes. We had a close run-in with one last week; the kids ran up the beach asking for a bucket to put their ‘new friend’ in!
They’d found a sea snake on a quiet Bali beach and thought they’d play with it. One venomous bite from a sea snake in Bali and you’re dead, there’s no cure.
If you see a sea snake do not touch it, they are extremely poisonous. A sea snake can still bite after it is dead due to a persistent bite reflex, (even with its head cut off) so give it a wide berth.

Bali Snakes (Land, not Sea Snakes)
It was reported on the news that a 10-year-old boy has tragically died from being bitten by a venomous snake. Bali does not have all the anti-venom for the venomous snakes that live on the island so practice extreme caution in the jungle or leafy areas.
Bali has several species of snake including the King Cobra, Spitting Cobra, pythons some others — however, we have been here for months and haven’t seen one snake.
It is extremely unlikely you will come across any of these on a Bali holiday as they like to stay well away from humans. Remember they are more scared of you than you are of them!
If you do see one do not touch it and get in touch with the free Bali reptile rescue service via Facebook which will relocate it to a safe environment.
Bali Komodo Dragons
Komodo dragons are not on Bali island itself despite being one of the most famous Bali animals. However, you can go on trips to visit Komodo dragons from Bali on four islands in Komodo national park.
The islands are reviewing their visitor policies due to Komodo dragons being unfortunately stolen so do check what is open.
If you are lucky enough to go, obviously listen to your guide and don’t do anything silly like try to take a selfie with one. They have a poisonous bite and very sharp teeth; last year someone was bitten severely. You have been warned!
Bali Monkeys
Bali is home to a lot of monkeys and there are attractions like Monkey Forest where interaction with the monkeys is encouraged. I strongly advise against this.
You may also see handlers on the street offering monkeys to hold for photos. Please don’t do this as it encourages animal exploitation and the monkeys are very poorly treated.
Tourists are often bitten and there is a very real chance of rabies. If you get bitten you need to seek treatment for rabies immediately.
Remember Bali often does not have the right treatment which means flying to Singapore, so it is much better to avoid it in the first place.
Stonefish & Sea Urchins
Stonefish and sea urchins are common Bali animals among coral reefs and rocks in the ocean. Wearing waterproof shoes is good protection for your feet, as is not stepping on coral.
Please don’t do this anyway as the coral is very delicate and easily damaged. There are also red sea cucumber creatures that the locals say are poisonous; the general rule of thumb is don’t touch stuff to keep safe!
A Word on Sharks In Bali
Bali shark attacks are almost unheard of, and no fatalities have been recorded. There have only been three recorded since 1900 and these occurred at Balian, which has a murky flowing river running into the sea. While considering dangerous animals in Bali I absolutely would not worry about Bali sharks, the chances of an attack are tiny.
Are there tigers in Bali?
Unfortunately not. There used to be three species of Indonesian tigers- the Bali tiger, Sumatran tiger, and Java tiger. The Java tiger and Bali tiger are extinct and the Sumatran tiger does not live in Bali.
Summary Of Bali Dangerous Animals
All in all, we find Bali to be a very safe and pleasant island (apart from the recent earthquakes- see this post on our experience of the Bali earthquakes for an update). Balinese people are extremely friendly, there is stunning nature and the Bali animals are not something to be put off by at all.
I felt as safe there as a woman as I do in London. We love being here with our three young children and I would wholeheartedly recommend it as a holiday or adventure destination! To plan a great Bali holiday see our resources below.

I knowthis is upsetting but what is the alternative? The people who sell the turtles what is their options? It is a genuine question.x

As a veggie, I completely share your views on animal welfare. you will see poor people trying to profit from animals, but you’re more unlikely (hopefully still) to see the deliberate animal cruelty that takes place in the uk. We can judge other cultures, but I doubt many Balinese people would deliberately hurt animals, for sport, or no reason, or for ‘fun’ as happens in the uk. In Thailand, many places, it’s all about money… maybe work for an animal sanctuary? Also most wont have £1000 per month to keep their families, so perhaps get to know people and understand their feelings, culture and needs. I’m not judging you, either, just saying that life is hard, people do what they can to support families. The western world keeps many people poor, so try and help people find a better way to make money? Difficult, I know, but can happen. I think the most dangerous animals In Bali are probably monkeys, as can be vicious, and can have rabies? I wish you all the best of experiences, admire your courage, and hope you have an amazing time.

Unfortunately there is deliberate animal cruelty here, cockfights are very popular for example. I don’t judge people for trying to make money, it’s heartbreaking to see though. I think as a planet we need to ensure that people are provided for so they don’t feel they have to resort to animal cruelty. We have made lots of friends here in Bali and are getting to know the culture very well- our main reason for traveling is to work for a charity that empowers vulnerable children so hopefully we will be part of the solution soon 🙂 Thanks for your kind comments!
mike says
to understand bali you need to inderstand its religion and how they treat animals…like MANY NOw and many well meaning westerners before you, you will find animal welfare is shocking anywhere in asia but unfortunately what is being done is HAVING little IMPACT CONSIDERING the size of the animal population, this is merely a feelgood exercise for westerners.
Cambodia amd VIETNAM is really what i think is the only place in S.E.A that you can help vunerable children but be WARNED….Many ORPHANAGES are money MAKINg SCAMS….Contact the N.G.O- concert, in siem reap they will PUT you in contact with LEGITIMATE charitable organizations. They ARE Tightening up on charitable tourism now unless you have a legitimate planed itinerary…
ENJOY….I.Wish you luck ?
Anjolie Williams says
I’ve never been to Bali or anywhere in S.E.A for that matter. I would say that common sense is KEY. I am not going to see a cobra or a komodo and walk up and pet it. That would be completely ignorant, and “insane”, although I do know people who would, just to say they did, that is, If they lived through it. All animals have the possibility of being dangerous, including the human kind. Again, common sense is the operative word here. I do think, in this day and age, that human animals can be quite dangerous. That being said, I am not going to walk up and pet one of those, either. I would just say, to be careful and especially traveling with children. Learn about the native animals where you will be traveling to. And if traveling with children, teach them to respect the animals, domestic and wild. Be responsible where ever you go in this world. There is animal cruelty, everywhere, here and abroad!!

Our daughter had to return home from study abroad in thailand, she went to bail for 9 days and planted coral and worked in a rice field. she came back with strange red streaks on her leg with a bump in between these streaks. she had visual problems and is still experiencing tremors. after seeing 10 docs in thailand, getting a brain mri and many blood tests, we brought her back to the usa…she still is undiagnosed…anything you can think of? one doc suspects ciguaterra poisoning but we are thinking it is some sort of bite to the leg while she was planting coral.

I’m a SEASONED TRAVELLER TO BALI, IN TOTAL, both myself and partner, have been 10 + times. Either you’re a liar or have been very unlucky. And yes we do go off the beaten track and I’ve got 20+ scuba dives under my belt. Oh by the way, sea snakes are venomous not poisonous, I wouldn’t recommend eating one.
Adventure Travel Family says
Hi Mark, I suggest reading the posts where I discuss my daughter’s brain injury in Bali where we experience the abysmal healthcare, followed by the earthquakes that we couldn’t escape from because she couldn’t fly due to her injuries. Yes, we were unlucky. So glad to know you’re a SEASONED TRAVELLER IN BALI, I lived there for 8 months and got to know many locals who have been bitten by snakes and dogs- the area we were in was particular bad for dogs. Bye!
