Go deeper than the day-trippers: a night at a river camp under tarpaulins, dinner cooked over a fire, a dawn swim, and a long loop into older forest where truly wild orangutans live, before tubing home down the gorge.
The sounds are what people remember: cicadas at dusk, rain on the tarp, the river, and at dawn the whooping of gibbons and the boom of siamangs echoing across the valley.
Two days, one night takes you to a riverside camp of tarpaulins and bamboo platforms, where guides cook over a fire. The second morning includes a swim and a longer loop into older forest where truly wild orangutans live, followed by the tube ride home through the gorge. Porters carry the food and camp gear; you carry water and a change of clothes in a dry bag. Nothing is luxurious and everything is memorable.
Three days and beyond pass the semi-wild zone into forest where sightings are rarer and the animals warier, with two camps, river crossings, and a chance of siamangs, hornbill flocks and the tracks of deer and sun bears. Longer five- to seven-day expeditions head towards Ketambe on the Aceh side or into the Leuser's mountains. The best guides are booked ahead in July and August.
The classic overnighter; longer treks add further camps beyond it.
Cross the river and climb into the forest near the village, with good odds of orangutans in the first hours.
Steep, muddy descents bring you to a riverside camp. Swim, wash, drink sweet tea while dinner cooks.
Curry, rice and fruit by candlelight, card games, and a night walk with a torch for insects and frogs.
A longer loop through taller, quieter forest where wild orangutans, siamangs and hornbills live.
Back at camp, your guides lash tubes together and you ride the river down through the gorge to the village.

Book with licensed guides through your guesthouse or the guides' association. For three days or more, choose an experienced guide and meet them first.
Slopes are steep and slippery, and humidity is relentless. Two days suits most fit walkers; three or more needs real stamina.
Carry out all rubbish and ask your guide to do the same; good guides do.
