The Sun Koshi (Grade 4 to 5) is Nepal's second offering for expedition rafting. With a put-in only three hours drive from Kathmandu, it is more easily accessible than the Karnali of offferring an incredible stretch of exhilarating white water. The run is 270 km and requires 8-10 days tocomplete with road access only at the beginning and end. On the third day rapids reach the upper 4 classifications and the remainder of the trip is consistently intense - the white water stays white until the very end.
