On the way from Dehradun to the Rupin Pass trek base-camp
The Rupin (with its twin, Nalgan) pass over the Dhauladhar range of mountains in Kinnaur, HP, affords the only possible entry from Uttarakhand into the overwhelmingly beautiful Sangla valley of Kinnaur. As I have said in the title note, there aren't too many valleys in this country of comparable charm. The approach to the pass is along the Rupin river, which is followed nearly to its source in the upper reaches. The base-camp is a hamlet called Dhaula of less than 10 homes, slightly ahead of Naitwar which is located at the confluence of the Rupin and the Tons, a major tributary of the Yamuna. These are all in north-west Garhwal. Naitwar can be reached after a nearly 170-km, full day's drive from Dehradun. It's a mostly picturesque 8-hour journey, passing through Mussourie, Naigaon and Purola. The trek naturally starts the day after.
