The first day you drive west of Kathmandu for Damouli roughly 160 km way. After the raft are rigged, you set off down the Seti River. YOu spend the whole day within its forested canyon.
In the afternoon a small outfitter but technical rapid is encountered near the village of Saranghat. The first night's camp is a spacious beach below the village. The next day you encounter a rapid graded between 3-5 before reaching Trishuli River. The topgraphy gets changed dramatically. The twisted severe rock formations give way to sandstone and gravel deposited by the antecedent river. After lunch you can visit a unique religious place called Devghat. At this point where the Kali Gandaki Joins the Trishuli and becomes the narayani River, you get a choice between coming back to Kathmandu or continuing the journey to visit the Chitwan National Park.
