Another river easily reached from Pokhara, the Seti (or Seti Nadi) offers a gentler alternative to the Upper Kali Gandaki. It’s a fairly tame (Class 3-) but very picturesque river, taking two or three days to float from Damauli to near Narayanghat.
This is a better choice than a similar trip starting on the Trisuli, as it takes you away from the road and has a fine green “jungle corridor” in its lower section, and beautiful white-sand beaches for camping. It’s a popular choice for birdwatching groups, who often schedule it into their itinerary from Pokhara to Chitwan. The water temperature is incredibly warm, making it a popular choice for winter trips and for kayak clinics.
