Raft through the forested gorges of Arunachal Pradesh on the mighty Siang, combining powerful whitewater, remote river beaches and a 180-kilometre journey from Tuting to Pasighat.
The Brahmaputra rafting expedition follows the Siang through Arunachal Pradesh, where a vast river threads between steep, densely forested hills. Beginning near Tuting, the route travels approximately 180 kilometres downstream to Pasighat, linking remote gorges, riverside settlements and broad beaches used as expedition camps.
The journey alternates between powerful whitewater and quieter stretches that reveal the surrounding landscape. In the Ninguing and Marmong gorges, forest crowds the riverbanks and the scale of the water becomes especially apparent. Rapids such as Pulsating Palsi and Moing Madness punctuate the descent, demanding concentration and coordinated paddling.
Beyond the rapids, the expedition develops its own daily rhythm. Packing camp, travelling downstream and settling onto another river beach before evening. With limited outside access through the gorge sections, the experience depends on the skill of the river team and the group’s willingness to embrace several days of remote camping.
Powerful whitewater and remote river camping.
Big-water rapids, cold nights and limited evacuation access.
Arrive in Dibrugarh and travel by road to Pasighat. Meet the expedition team before the journey up the Siang valley.
Drive upstream through forested hills and Adi settlements, stopping overnight around Yingkiong.
Continue north to the expedition base near Tuting and settle into camp beside the river.
Fit rafting equipment and practise paddle commands, rescue procedures and responses to a capsize before beginning the descent.
Begin rafting through the upper Siang valley, where quieter stretches give way to powerful whitewater. Ninguing and Pulsating Palsi bring the first major challenges, with Grade IV–V rapids before a beach camp near Pango.
Scout Pango rapid before entering the forested Marmong gorge. Negotiate Grade IV rapids at Pango, Rikor and Zebra Rock, then camp near Cherring, upstream of Tooth Fairy.
Walk around Tooth Fairy, a Grade VI rapid, while the crew transfers the rafts and equipment. Continue through Grade III+–IV whitewater, including Hairy Hari and Broken Oar, before reaching Paradise Beach.
Spend a day at the riverside camp, recovering from the gorge section. Rest on the beach or take an optional short walk before the remaining river stages.
Begin with Moing Madness, generally described as Grade IV–IV+, before reaching easier stretches near Nubo. Further downstream, negotiate Karko rapid and continue to the beach camp near Geku.
A gentler day of long floating sections past riverside Adi settlements. Pass the confluence with the Siyom before continuing downstream to camp near Rotung.
Negotiate Ponging, the final major Grade IV rapid, before the valley opens toward the plains. Continue along the widening Siang to the expedition’s take-out near Pasighat.

Trips may be possible, but departures and river conditions vary. Confirm the full expedition with the operator.
Heavy rain, powerful flows and landslide disruption make this unsuitable as a normal expedition-planning window.
River levels and access roads are recovering from the rains; departures depend on current conditions.
Confirm current Siang water levels, road access and scheduled expedition departures before booking.
This is a demanding expedition with limited road access through the gorges. Previous rafting experience, good fitness and confidence in moving water are strongly advisable. Choose a specialist operator with safety kayakers, rescue-trained guides and a clear evacuation plan.
Current permits and rafting regulations may change. Always verify before booking.
