Sunder Dhunga Valley means the "Valley of beautiful stones". The trek is a little more meticulous than its better known "cousin's" of Pindari and Kafni. Once we reach the top, we will have all the answers regarding its name. It is visited by many tourists who come to Uttaranchal.

The valley Sunderdhunga lies along Sunderdhunga gad (Stream) which sticks together the Pinder River just below the Khati village. There is a village called as the last village on the Sunderdhunga valley, which is just 7 km away from Khati. Beyond Jatoli there is nature at its best Rippling streams, waterfalls, undisturbed wildlife and open meadows. Apart from this, there is a towering southern ring on the Nanda Devi Sanctuary whose peaks like Mrigthuni, Maiktoli, and Panwali Dwar are adjoined together with sharp ridges and hanging glaciers, dominate the Sunderdhunga valley. The upper reaches of the valley open at the meadows of Kathalia where local shepherds move in with their flocks during summer. The lush green meadows named Bal Top and forest of Rhododendrons and Juniper can be seen while travelling.
