Kalimantan, the Indonesian part of Borneo, forms the largest part of the island within the Indonesian archipelago and is one of the world’s great wilderness destinations. Vast rainforest stretches across its interior, criss-crossed by rivers that have been the lifelines of local communities for generations. While many travellers know Kalimantan through its famous orangutan encounters along the Sekonyer River, there is another side of the island waiting to be explored.
Rather than flying to Pangkalan Bun and following the familiar route into Tanjung Puting National Park, this journey begins in Palangka Raya, the capital of Central Kalimantan. From here, the road leads to Kasongan, where a traditional riverboat becomes the gateway to the Katingan River, Sebangau National Park and the remote waterways of the island’s interior. The experience is less about searching for one particular wildlife encounter and more about discovering the landscapes, communities and rhythms of life that unfold along the river.


And while the journey takes you deep into the wild, it doesn’t mean leaving comfort behind. The riverboat combines the character of a traditional Kalimantan klotok with the comforts needed for several days on the water. With only a few cabins and meals served on board, it feels intimate and personal a floating base from which to watch the rainforest unfold.
As the riverboat moves deeper into Kalimantan, the landscape gradually changes. Forest replaces settlements, smaller waterways lead away from the main river, and tiny riverside villages appear along the banks. These encounters offer a glimpse into a way of life shaped by the waterways and forests for generations, revealing another side of Kalimantan that few travellers get to experience.


The journey also offers opportunities to venture beyond the riverboat. Canoes carry travellers into the waterways of Sebangau National Park, where dense rainforest gives way to short treks beneath the canopy, or into the blackwater lakes and forested channels of the Klaru River. Wildlife may appear along the way, from proboscis monkeys and other forest inhabitants to a remarkable variety of birdlife, but sightings are only part of the experience.
And then there are the moments that cannot be planned: waking to mist hanging over the river, watching reflections ripple across the dark waters at dusk, sitting on deck as the forest passes slowly by, or falling asleep to the sounds of the rainforest, far from the roads and towns.
Adventure is about stepping outside the familiar and coming home with a story. In Kalimantan, that story might be one of rainforest, riverside communities, unexpected wildlife and days spent following the water as the destination reveals itself one bend at a time.


Some adventures are about reaching a destination. In Kalimantan, the adventure is the journey itself – following remote rivers, discovering rainforest and communities, and letting the island reveal itself one bend at a time. Contact [email protected] to explore the journey.
