From the heights of the Himalayas, rivers surge down the foothills and across the plains of Nepal enabling some of the most scenic, exciting and challenging white water rafting experiences in the world. There are rivers presenting a wide range of difficulties and a selection of rafting companies offer different types of trips, from gentle drifts ideal for families, grade two to three rapids for first timers, or world-class raging white water for brave and experienced paddlers seeking the ultimate adrenalin rush. Rafters can also choose from two-day to two-week trips that usually involve some trekking, and the options include paddling, oaring or kayaking. Kayak clinics are also available on the Seti River. The most popular white water rafting trip from Pokhara is on the Kali Gandaki River with extreme rapids (grade 5 to 5+) and impressive scenery as the river winds its way through canyons and deep gorges. Those looking for multi-day adventures should tackle the Marsyandi River (four days), the Sun Koshi River (seven to nine days), the Arun River (nine days), the Karnali River (10 days), or the Tamur River (11 days). Rafters will spend nights camping on the river banks in glorious surroundings and will witness some of Nepal's most awe-inspiring scenery while on the water.
