Mere interest in the adventure is not enough to opt for Bhotekoshi Kayaking as it is full of extreme and high Rapids and demands you with extra carefulness.
The Bhote Koshi runs alongside the Arniko Highway to the Tibetan border northeast of Kathmandu. Bhotekoshi Kayaking would be extra demanding because the river is possibly taken as the steepest and hardest commercial rafting river in Nepal. To be clear, it is marked under (Class 4+). With this you can simply image the wild thrill you would get in Bhotekoshi Kayaking. However, the feeling you would get is quite explainable.
You would feel like a ball in a pinball machine in low water. As you hit the medium flows, you would feel like you are being flushed down and more than that is something left to be felt by yourself. The bottom-line is Bhotekoshi Kayaking provides a special edge to your adventure diaries and it is worth a try.
