This trek is actually an ancient route of Gangotri to Kedarnath. The Hindu devotees used this pilgrimage trail very regularly during the times when roads didn't exist and people used to visit all the four holy temples on foot. Gangotri and Kedarnath are Panch Prayags of North. In Gangotri you can see Gaumukh also which is the source of holy river Ganges. The Kedarnath shrine, built in the 8th century is dedicated to Lord Shiva. Kedar is another name of Lord Shiva, the protector and the destroyer.
