The wild snow-fed rivers of Himachal Pradesh are paradise for extreme kayakers and novice white water rafters alike. There are many Himalayan rivers to explore in Himachal pradesh; with most prominent being The Chenab also known as Chandrabhaga in Lahaul, Ravi river near Chamba, Satluj near Shimla and Beas river in Kullu valley. Beas has been more favorite and explored of them all and is one of the most favorite and busy rafting destination in north India after Ganges.
The Beas is a popular Indian river about 200 miles to the northwest of the Upper Ganges in Himachal Pradesh. Like the Upper Ganges, the Beas is also mostly fed by snowmelt from the high peaks of the Himalayas. A road follows the river from the mountain resort town of Manali (Elevation 2050 meters). Here it is relatively small and makes a steep descent through the upper Kullu Valley.
From Manali to Mati Bagh is a difficult experts run but then it starts getting more manageable as it goes into the valley. It's class 4 then class 3 down to where the river drops down in the lower gorge This section is even tougher than the upper gorge and has much more water.
