Sarain FRH dates back to 1914. This is about 13kms from ChopaI. The rest house is surrounded by extensive woods of pine, deodar and fir. Sarain is one of the starting points of the trek up to the peak of Choordhar. The peak is crowned by a temple dedicated to Chooreshwar Mahadev, and to Shirgul Maharaj. Shirgul is a deity who is widely worshipped in Chopal and in district Sirmaur. The most popular legend about Shirgul is of the time he went to Delhi with hundreds of his followers. The people of Delhi were wonderstruck with his divine powers. A king of Delhi used leather shackles to curtail the powers of Shirgul and had him imprisoned. Then the king Gogapeer of Bangardesh, took the help of Mata Bhangyani and they were able to rescue Shirgul. The shrine of Bijjat Maharaj, a local manifestation of Bhagwan Shiva, where he appears as a bolt of lightning, is also accessible from this rest house.
