Marshyangdi River

The Marshyangdi River drains the Annapurna and Manaslu massifs of central Nepal, and its upper gorges deliver some of the most exhilarating multi-day whitewater in the Himalaya. The name means Raging River, and the steep, glacier-fed torrent lives up to it through mile after mile of continuous rapids.

The classic run below the trekking town of Besisahar is demanding, near-continuous Class IV with Class IV+ sequences, a fast staircase of crashing waves and technical drops framed by snow peaks. There is little respite between rapids, and the cold, silty glacial water and remote canyon make this a committing expedition for experienced crews. Construction of hydropower dams has altered access, so paddlers should confirm current runnable sections.

The scenery is exceptional, with the trail of the Annapurna Circuit tracing the valley above, terraced fields, Buddhist villages and prayer flags marking the transition from Hindu lowlands to Tibetan highlands. Trips typically camp on beaches and combine paddling with a taste of the region's celebrated trekking culture. Access follows the lower Annapurna Circuit road, and paddlers should verify which reaches remain free-flowing, since several hydropower projects have altered the once-continuous run in recent years.

Prime conditions arrive in the post-monsoon window of October to November, when high water recedes to powerful but clearer flows, and again briefly in April and May. The Marshyangdi is colder, steeper and far more serious than the Trishuli, and it rewards fit paddlers with a genuine high-Himalayan whitewater journey beneath some of the tallest mountains on Earth.
