River rafting is a spine tingling and adrenaline gushing sport for the adventurous ones. The feel of the icy cold water splashing against the face while you struggle to steady the unsettling raft over the foamy turbulent waves of the serpentine river will stimulate your adventurous streak. The magnificent untamed crystal-clear waters of Kosi River that flows by the national park provides the ideal location for this thrilling experience. Guided rafting tours are available to provide a safe and amazing involvement. This activity can be enjoyed by both experts and beginners. The view by the river side against the backdrop of the mountains is a feast to the eyes.
However, river rafting is a seasonal activity here. It can be only enjoyed during the monsoon. Incase of heavy downpour, the Koshi River swells and it is too risky then. The best time for river rafting is July to September.
