Tanjung Puting National Park: The Complete Visitor Guide

Tanjung Puting National Park covers about 4,150 square kilometres of Central Kalimantan, on the Indonesian side of Borneo, and there is not one road inside it. You arrive by river or you do not arrive. That single fact shapes everything else on this page: how you get in, what you sleep on, how long it takes to see anything, and why the whole business runs on slow wooden boats instead of minibuses.

We charter those boats and we work this river. So take the enthusiasm here with the appropriate pinch of salt, and hold us to the parts that are checkable. Every number below has a source, and where we could not verify something we say so instead of rounding it into confidence.

What the park actually is

The Dutch colonial administration protected this block of forest as a game reserve in 1936, at around 305,000 hectares, specifically for orangutans and proboscis monkeys. Indonesia declared it a national park by ministerial decree in May 1984. A 1996 decree redrew the boundary at 415,040 hectares, which is the 4,150 square kilometres you see quoted almost everywhere, and it folded in three different things: the old wildlife reserve, about 90,000 hectares of former production forest, and roughly 25,000 hectares of water.

One wrinkle worth knowing, because it explains why sources disagree. The Ministry of Forestry now publishes the park at 412,548 hectares, slightly smaller than the 1996 figure. That is not a shrinking park. It is the difference between a boundary drawn on paper and the same boundary walked and surveyed on the ground. Either number is defensible. We use the rounder one.

Two designations get confused constantly, including by people selling trips here. Tanjung Puting is a UNESCO Biosphere Reserve, designated in 1977 under the Man and the Biosphere programme, and a Ramsar wetland site since 2013. It is not a UNESCO World Heritage Site. Indonesia has nine of those and this is not one of them. If a brochure tells you otherwise, that brochure was not checked.

The biosphere reserve is also much larger than the park, at 938,247 hectares, because a biosphere reserve wraps buffer and transition zones around a protected core and adds a marine component. Quoting that number as the park's size overstates it by more than double. It happens a lot.

The land itself is flat and low, nought to eleven metres above sea level, sitting on peat domes six to seven metres deep in places. Rainfall runs around 2,400 millimetres a year and the temperature sits between 25 and 27 degrees with humidity in the eighties. In practice that means warm, wet, and buggy, and it means the peat soil is acidic enough that the forest growing on it is a specific and unusual thing rather than generic jungle.

The river is the road

The Sekonyer does three jobs at once. It is the park's legal northern boundary, it is a named watershed, and it is the only practical way in for a visitor. Boats leave from the harbour at Kumai, run a short stretch along the Kumai river, then turn into the Sekonyer. That turn is effectively the park gate.

From Kumai, a klotok takes roughly two hours to reach the first feeding station. Klotoks are slow by design, and the time varies with water level, engine size, how loaded the boat is, and how often the crew cuts the engine because somebody spotted something. Treat every duration on this page as a range rather than a timetable. Speedboats do the same runs in a fraction of the time and we do not recommend them for anything except a day trip, because the point of a klotok is that you are inside the park after dark and speedboats are not.

You sleep on the boat. The lower deck is engine, galley and crew. The upper deck is yours, open-sided with a roof, and at night a mattress goes down under a mosquito net with the river running a metre below you.

The three feeding platforms, and what they are for

Going upstream from Kumai the order is Tanjung Harapan, then Pondok Tanggui, then Camp Leakey. Rangers put fruit and milk out on a raised platform at a fixed hour and visitors watch from a distance.

As of June 2026, the posted times were 3pm at Tanjung Harapan, 9am at Pondok Tanggui, and 2pm at Camp Leakey. That schedule has been stable for years, but it is a park operational decision and not a law, so confirm it with your operator before you build a plan around it.

Here is the part that marketing tends to skip. These platforms are a rehabilitation tool, not a show. Orphaned and confiscated orangutans were released into this forest over several decades, and supplementary feeding carried them, and later their wild-born young, through the lean fruiting months. The animals are free-ranging and unfenced. None of them is required to turn up.

That last point is not a disclaimer we are legally obliged to print. It is the actual mechanism. In a strong fruiting season the forest offers better food than a platform does and attendance drops sharply. Orangutan Foundation International has described visitors seeing not a single orangutan at a feeding station for weeks at a time when wild fruit was abundant. Nobody controls that. Any operator who tells you otherwise is telling you something about themselves.

Two other sites turn up in itineraries and are worth naming so you know what they are. Pesalat and Beguruh are reforestation and replanting sites, not feeding stations. Pondok Ambung is a tropical forest research station, run with the Orangutan Foundation, where a lot of the park's camera-trap work happens. None of the three is a place to watch orangutans eat.

Camp Leakey

Camp Leakey is where most of what the world knows about wild orangutans came from. Biruté Galdikas set it up in 1971 and it grew into one of the longest continuous studies of any wild primate anywhere. She died in March 2026.

The platform there was built as a rehabilitation tool, not an attraction. Orphaned and confiscated orangutans were released here for decades, and the fruit and milk carried them through the lean months. That programme did its job and wound down, and the last releases were in the mid-1990s. What is left is a feeding platform that wild, free-living animals visit when they feel like it, and in a good fruiting season that can mean not at all for weeks. Sightings there are unreliable now.

So our three-day trip does not go. Camp Leakey sits a long way upriver, up a narrow blackwater branch called the Sekonyer Kanan, and the round trip costs the better part of a day in transit. We would rather give you those hours in the forest and on the water, where the wildlife actually is. If the history is why you are coming, and for some people it genuinely is, our four-day three-night itinerary includes it.

What lives here

Start with the animal everyone comes for. The orangutans here are Bornean orangutans, Pongo pygmaeus, of the subspecies Pongo pygmaeus wurmbii. The species is listed as Critically Endangered by the IUCN, assessed most recently in 2024, with a species-wide estimate of around 104,700 animals against a 2016 baseline.

We cannot give you a credible orangutan population figure for this park alone. Numbers between 30,000 and 40,000 circulate on tour websites and they are not believable, because they approach the entire global estimate for the subspecies. The Orangutan Foundation reported over 5,000 across Tanjung Puting and the neighbouring Lamandau reserve combined in January 2025, and that is the most honest figure we found.

Beyond the orangutans, and verified species by species against IUCN assessments rather than copied off a competitor's list:

• Proboscis monkey, Nasalis larvatus, Endangered. The ones with the noses, best seen from the boat in the late afternoon when they come to the riverside trees to sleep.
• Bornean white-bearded gibbon, Hylobates albibarbis, Endangered. Heard far more often than seen. Note the name: plenty of sources, including one UNESCO page, list the agile gibbon or Müller's gibbon for this park. Both are wrong. Those species live elsewhere on Borneo.
• Red leaf monkey, Presbytis rubicunda, Vulnerable.
• Long-tailed macaque, Macaca fascicularis, Endangered. Its status was challenged and the IUCN upheld it in October 2025.
• Sunda clouded leopard, Neofelis diardi, Vulnerable. Not the mainland clouded leopard, which is a different species and another name that gets misprinted for this park. In April 2026 camera traps run jointly by the Orangutan Foundation and the park recorded a female with two cubs, which is an unusual and encouraging record.
• Malayan sun bear, Helarctos malayanus, Vulnerable.
• Hornbills. Three species are confirmed by georeferenced records inside the park: rhinoceros hornbill (Buceros rhinoceros, Vulnerable), black hornbill (Anthracoceros malayanus, Vulnerable), and oriental pied hornbill (Anthracoceros albirostris, Least Concern). Borneo has eight hornbill species and others may well be here, but those are the three we can point at a record for.

Over 200 bird species are recorded in the park. That figure traces back to fieldwork published in the late 1980s and nobody appears to have redone the survey since, so treat it as a floor.

You will also see banteng, the wild cattle, on some operator lists. We left them off. The claim traces to a single guidebook sentence from 1994, a peer-reviewed mammal survey inside the park did not find them, and the current IUCN assessment does not mention this park at all. They may have been here once. We are not going to tell you that you might see one.

The animal nobody puts in the brochure

Tanjung Puting holds what the IUCN's own assessment calls the most secure population of false gharial, Tomistoma schlegelii, anywhere in the world. It is an Endangered freshwater crocodilian with a long narrow snout, and the breeding population near the park headquarters sits at a recorded density of 1.4 individuals per kilometre, the highest measured for the species anywhere in the wild.

That is a genuinely significant thing and it appears on almost no tour operator's page, including, until now, ours. It is also a useful corrective to the idea that this park is an orangutan attraction with some scenery attached. It is a working piece of protected wetland that happens to be the best place on earth for an animal most visitors have never heard of.

The honest part

A guide that only tells you what is thriving is a brochure. Two things sit uncomfortably alongside everything above.

The first is a fifty-year study at Camp Leakey, published in 2023, which counted adult male orangutan encounters in the same study area at ten-year intervals. In 1976 there were about 40. In 2016 there were two. The researchers, Galdikas among them, attribute that to deforestation by palm oil companies and timber estates, to development, and to habitat fragmentation that stops males dispersing normally. They use the phrase pre-extinction.

The second is that the park is an island. The protection stops at the boundary and the pressure does not, and a protected core surrounded by plantation is a harder thing to keep alive than a map suggests.

We are not telling you this to be gloomy or to make a visit feel virtuous. We are telling you because the alternative is selling you a postcard, and you can get one of those anywhere.

Fees, permits and paperwork

Entry fees are set nationally by government regulation, not by the park, and they run per person per day. Under the regulation in force since October 2024, a Class 1 national park charges Rp 250,000 per foreign visitor per day and Rp 50,000 per Indonesian visitor, with a 150 per cent surcharge on public holidays that applies to Indonesian visitors only. Tanjung Puting was announced as Class 1 in November 2024.

Now the caveat, and it is a real one. A ministerial regulation that took effect on 2 November 2025 reassigned park ticket classes nationally, and it demonstrably moved some parks between classes. We could not confirm Tanjung Puting's class under that new regulation. So treat the figures above as the shape of the thing rather than a quote, and get the current number from your operator or the park office before you travel. Anyone printing a confident rupiah figure right now is guessing.

Other charges that catch people out: flying your own drone is Rp 2,000,000 per day, and commercial photography and filming carry separate and much larger fees. There is no ordinary tourist camera fee.

You do not need a SIMAKSI permit to visit as a tourist. That permit covers research, education, film-making, expeditions and journalism. Ordinary visitors pay the entrance ticket, which your operator normally settles at Kumai or the park office. If you are coming to write about the park, that is journalism, and you do need one.

How long you need

Two nights is the practical minimum. One day is a long way to fly for a few hours on a river. Three nights opens up the quieter upper river and takes the schedule pressure off, and it is where Camp Leakey fits without squeezing anything.

There is no closed season and no month with no orangutans. Roughly May to September is drier, which makes walking easier and nights more comfortable. The wetter months bring higher water, which changes what the boat can reach.

Frequently asked questions

Is Tanjung Puting a UNESCO World Heritage Site? No. It is a UNESCO Biosphere Reserve, designated in 1977, and a Ramsar wetland site since 2013. Those are different programmes with different lists. Indonesia has nine World Heritage sites and this is not among them.

How big is Tanjung Puting National Park? About 4,150 square kilometres, or 415,040 hectares, under the 1996 boundary decree. The Ministry of Forestry currently publishes 412,548 hectares after ground survey. Do not confuse either with the 938,247 hectare biosphere reserve, which is a much larger area including buffer zones.

Will I see an orangutan? Probably, and we will not put a number on it. The feeding platforms are the likeliest hour of your day, but the animals are wild and unfenced and in a good fruiting season attendance drops sharply. Nobody can promise you a sighting, and an operator who does is telling you something useful about themselves.

Can I visit in a day? You can, by speedboat, and we would rather you did not. A day trip means arriving, watching one feeding session, and leaving. The park is at its best at dawn and dusk and after dark, and a day trip gives you none of those.

Do I need a permit? Not as a tourist. You pay a per-person-per-day entrance fee, normally handled by your operator. A SIMAKSI permit is required for research, film-making, expeditions and journalism.

How much does it cost to get in? Fees are set by national regulation, per person per day, and differ for foreign and Indonesian visitors. A national reclassification took effect in November 2025 and we could not confirm the park's current class, so ask your operator for the current figure rather than trusting a number on a website, including this one. However, our tours all include the entrance fee, so that's one thing less for you to worry about.

Are there roads in the park? None. Access is by river from Kumai harbour, and the nearest airport is Pangkalan Bun. This is why almost every visit here happens on a boat.

What else lives there besides orangutans? Proboscis monkeys, Bornean white-bearded gibbons, red leaf monkeys, macaques, sun bears, Sunda clouded leopards, at least three hornbill species and over 200 birds. The park also holds what the IUCN calls the world's most secure population of the false gharial, an Endangered freshwater crocodilian.

Is it worth it? If you want an animal encounter you can put in a calendar, no, and we would rather say that now. If you want to spend three days on a river inside a working piece of protected forest, watching for something that owes you nothing, then yes.
