Batu Katak vs Bukit Lawang: Where to See Wild Orangutans in Sumatra?

Sumatra is one of the few places on Earth where you can still encounter orangutans in their natural habitat (the other one is Borneo). Most travelers head straight to Bukit Lawang, but if you want a more remote jungle experience, Batu Katak is an interesting alternative.

We visited both — spending two days trekking and camping around Batu Katak before continuing to Bukit Lawang. The experiences could hardly have been more different.

Our recommendation: If seeing orangutans is your main priority, choose Bukit Lawang. If you want a more remote and unpredictable jungle adventure, choose Batu Katak. If you have enough time, do both — that's what we would recommend.

Orangutan Trekking in Batu Katak

Batu Katak immediately felt different from the more established tourist destinations in Sumatra. It's a small village surrounded by rainforest, with only a handful of simple accommodations and very little tourism. The people are here very nice and they really care about you and they want to genuinely show their loved environment.

We headed into the jungle with local guides for two days and one night, with one main goal: finding wild orangutans.

And that turned out to be much harder than we expected.

We heard gibbons, found orangutan nests high in the trees and even discovered claw marks left by a sun bear. And we were completely alone in the jungle. No other tourist groups. It was very cool adventure. And we slept in an open air camp site in the jungle. The sounds… We will never forget it!

Orangutans themselves remained hidden.

That's also what made Batu Katak special for us. It didn't feel like we were walking to a known orangutan location. We were genuinely searching a huge rainforest for wild animals, and there was absolutely no guarantee they would appear.

We eventually finished the trek by rafting back toward the village on tubes tied together — a pretty perfect ending to two days in the jungle.

AND the most interesting benefit of going on a trekking in Batu Katak is actually a flower. Probably the most unique in the world. The Cropse Flower…

Finding a Wild Titan Arum – The Corpse Flower in Batu Katak

Orangutans weren't the only reason to visit Batu Katak.

One of the biggest surprises of our trek was finding a Titan Arum (Amorphophallus titanum) blooming completely wild in the Sumatran rainforest.

The Titan Arum is native to Sumatra and produces the world's largest unbranched flowering structure. It's also famous for something slightly less glamorous: its smell.

There's a reason it's called the corpse flower.

When blooming, it produces an intense smell similar to rotting flesh, which attracts the insects that pollinate it.

We were incredibly lucky because our guides found several plants at different stages. One was in full bloom, another was already dying, while a third was just beginning to emerge.

Seeing a Titan Arum blooming in the wild ended up being one of the unexpected highlights of our entire Sumatra trip.

Orangutan Trekking in Bukit Lawang

After two days of searching Batu Katak without seeing a single orangutan, we decided to try our luck in Bukit Lawang.

The difference was immediate.

Bukit Lawang is one of Sumatra's most famous orangutan destinations, with guesthouses, restaurants, souvenir shops and a much more established trekking industry.

And the difference wasn't only in the village.

After around 20 minutes of trekking, we found a mother orangutan with her baby high in the trees.

Two days versus twenty minutes!

Later, I continued trekking with our guide and encountered another male orangutan — this time down on the ground.

Bukit Lawang therefore delivered exactly what we had hoped for: incredible close encounters with Sumatran orangutans. But it was a very different experience from the wilderness and uncertainty of Batu Katak.

Batu Katak or Bukit Lawang: Which Is Better?

For us, there isn't really one winner.

Choose Batu Katak if you're looking for a remote jungle experience, fewer tourists, overnight camping and the excitement of genuinely searching for wildlife.

Choose Bukit Lawang if seeing orangutans is your priority, you have limited time or you prefer having more accommodation and tourism infrastructure.

If you have enough time, we recommend doing both.

Strangely, spending two days unsuccessfully searching for orangutans in Batu Katak actually made seeing them in Bukit Lawang feel much more rewarding.

Gunung Leuser National Park & the Leuser Ecosystem

Both destinations give access to the extraordinary rainforests of northern Sumatra and the wider Leuser Ecosystem, which includes Gunung Leuser National Park.

This is one of Southeast Asia's most important remaining rainforest landscapes and is home to an incredible variety of wildlife, including Sumatran orangutans, gibbons, sun bears, elephants and the extremely elusive Sumatran tiger.

You probably won't see most of them — we certainly didn't — but knowing they are somewhere in the forest makes trekking here even more exciting.

How to Get to Batu Katak & Bukit Lawang

We started our trip in Medan, the main gateway for travelers visiting this part of Sumatra.

The drive from Medan to Batu Katak took us around four hours, passing through towns, mountains and huge palm plantations before eventually reaching the rainforest.

From Batu Katak, you can continue to Bukit Lawang and combine both destinations rather than returning immediately to Medan.

We would allow around 4–5 days for the whole experience if you want to visit both without rushing.

What to Bring for Jungle Trekking in Sumatra

You don't need anything particularly technical, but prepare for heat, humidity, rain and mud.

We recommend lightweight long trousers, breathable clothes, proper walking shoes, insect repellent, rain protection, plenty of water and spare socks.

And be prepared for leeches.

Lots of leeches.

FAQ: Orangutan Trekking in Sumatra

Can you see wild orangutans in Batu Katak?

Yes, orangutans live in the forests around Batu Katak, but sightings aren't guaranteed. We trekked for two days and found nests and other signs without actually seeing an orangutan.

Is Batu Katak better than Bukit Lawang?

It depends on what you're looking for. Batu Katak is better for a remote jungle adventure, while Bukit Lawang gives you a much better chance of actually seeing orangutans.

Are the orangutans in Bukit Lawang wild?

The situation is more complicated than simply wild versus captive. The forests around Bukit Lawang contain wild orangutans as well as habituated animals and orangutans connected to the area's former rehabilitation program.

How many days do you need for orangutan trekking in Sumatra?

For Batu Katak and Bukit Lawang together, we'd recommend approximately 4–5 days, including travel between the destinations. A two-day/one-night trek worked very well for our Batu Katak experience.

Can you see the corpse flower in Sumatra?

Yes. Titan Arum is native to Sumatra, but finding one blooming requires considerable luck because the flowering stage is very short. Local jungle guides may know where individual plants are growing.

Our Final Thoughts

We came to Sumatra primarily to see orangutans, but Batu Katak ended up being memorable partly because we didn't find them.

For two days we were genuinely searching the rainforest without knowing what would appear next. We found gibbons, orangutan nests, sun bear signs, bizarre insects and a blooming Titan Arum — just not the animal we originally came to see.

Then Bukit Lawang gave us the orangutan encounters we had hoped for.

For us, combining Batu Katak and Bukit Lawang was the perfect way to experience this part of Sumatra: Batu Katak for the adventure, Bukit Lawang for the orangutans.
