The uppermost catchment of Ramganga East is lesser known and the least travelled region of Kumaon. It is also among the more difficult trekking areas of the higher Himalayas. In one day, one reaches Bala Village near the famous Birthi falls on the Thal Munsiyari route. On the second day, one can stay at Thala Bugyal. On the third day before reaching Sudam Khan one has to go through Thal - Thunk, Chafua, Ranthan and Malla Ranthan. On the fourth day after crossing Rahli, Nandakund and the ascent to Rumadhar, the trekker reaches Hiramani Glacier. The fifth is the memorable day as one sees the snout of Namik Glacier and the lesser stream coming down from Anargal to meet the main stream, after passing through Jogi Udiyar the ascent of Bhindawali and Penthang.
