This is a trans-Himalayan trek which commences at Munsyari(2290 mts) and the route ascends up the Gori Ganga river gorge which separates the Nanda Devi group from the beautiful peaks of the Panch Chulli group. The initial part of the trek leads you through the high Himalayan ridges to open up into the wide expanse of the gentler trans-Himalayan region. There are quaint Himalayan settlements on the way and villages like Rilkot and Martoli have houses that are at least one hundred and fifty years old reminding every one of the extent of Indo-Tibetan trade through the old silk route. Five days of steady walking takes you to Pachu(3950 mts) the base camp area for Nanda Devi East. The location is exquisite and we usually spend a full day over here. The return trip is completed in four days from here back to the Wayfarer Mountain Resort at Munsyari.
