We start early from Dehradun and drive through the villages of Damta, Purola, Mori, Netwar and reach Sankri by evening. Soon we start following the river Yamuna upstream. The river Kamal Ganga merges with Yamuna near Naugaon and will accompany us till Purola. Purola is the last big settlement on the way with a large market. The drive after Purola is through a beautiful forest of pine trees. From near the village of Mori, the river Tons flows beside us till about Netwar. The drop in temperature can be felt from here. We officialy enter Govind Pashu Vihar Wildlife Sanctuary after we cross a check post at Netwar. It can be considered the southern gateway to the sanctuary as most of the treks across the region are accessed from here onwards. Close to here the rivers of Rupin and Supin merge to form Tons, which is the largest tributary of Yamuna and in fact larger than Yamuna itself, in terms of volume of flow. The peak of Kedarkantha can be seen from various points along the way here.
We reach Sankri by early evening. It is a small village with a central market lined with a few shops. The village has numerous apple orchards. One can see the Swargarohini peak from here on a clear day. We rest at night in a guest house or in camps.
