“Bhote” roughly translates as “river from Tibet so there are quite a lot of rivers with this name in Nepal. This Bhote Koshi is the main branch of the Sun Koshi. The river is followed by the Araniko highway so access and scouting are relatively easy. The upper valley above Bahrabise is impressively narrow with steep hill sides shooting up over 2000m from the river. And there are some dramatic and scenic gorges down at river level. Just to drive up the highway and look at the river is like reading an erotic novel – it quickens the blood and excited the mind.
Technically, the upper Bhote Koshi ends just after Barbisae where the Sun Koshi joins as a stream from the left: The lower Bhote Koshi rafting start right from the Lamasangu.
