The Karnali Headwaters in Humla
The upper Karnali carves the gorges below Simikot — the headwaters of Nepal's longest river, fed from near Mount Kailash.
The upper Karnali — known locally as the Humla Karnali — carves the deep gorges below Simikot, the headwaters of Nepal's longest river. Rising on the Tibetan plateau near sacred Mount Kailash and Lake Mansarovar, the river enters Nepal in far-western Humla, and its valley is the natural highway that the treks to Limi and Hilsa follow upstream toward the border.
What to expect
From Simikot's ridge you look down on the Karnali winding through a steep canyon far below, its grey-green glacial water threading between pine-clad slopes and bare cliffs. As you trek out of town, the trail drops to the riverbank and follows the gorge upstream — past suspension bridges, tiny terraced villages and side streams tumbling in from the heights. This is some of the most dramatic river scenery in Nepal, made all the more striking by how few outsiders ever see it.
The upper Karnali is the connecting thread of Humla's great journeys. The Limi Valley trek and the Kailash route via Hilsa both follow the river out of Simikot before branching toward the high country and the border. Walking beside it, you are literally tracing Nepal's longest river back toward its sacred Tibetan source.
A river with sacred and wild significance
The Karnali is one of Nepal's last great free-flowing rivers, and its headwaters draw a direct line to the holy region of Mount Kailash, whose meltwaters feed the wider river system. Far downstream, in the lowland gorges, the Karnali becomes one of the country's premier whitewater rivers — the setting for the multi-day expedition described in our Karnali River rafting trip guide. But here in Humla it is a high, remote mountain river, experienced on foot rather than by raft.

Frequently asked questions
Where does the Karnali River begin?+
The Karnali, Nepal's longest river, rises on the Tibetan plateau in the region near Mount Kailash and Lake Mansarovar, entering Nepal in far-western Humla. The stretch that flows past Simikot is known as the Humla Karnali, the river's upper headwaters.
Can you see the Karnali at Simikot?+
Yes. Simikot sits on a ridge high above the Humla Karnali, and you look down on the river in its gorge from the town and surrounding viewpoints. The Limi and Hilsa treks then follow the river upstream through dramatic canyons toward the Tibet border.
Is the upper Karnali at Simikot good for rafting?+
The Humla Karnali near Simikot is high, remote and mainly walked rather than paddled. Nepal's famous multi-day Karnali rafting and kayaking expeditions run on the river much further downstream, in the lowland gorges, not in the high headwaters around Simikot.
Why are the Karnali headwaters significant?+
They form the source region of Nepal's longest and one of its last free-flowing major rivers, draining the far west. The river also links Humla physically and culturally to the sacred Mount Kailash region, whose meltwaters help feed the Karnali system.
