Kedartal (also known as Shiva's lake) is a glacial lake situated at an altitude of 4,750m (15,600 feet) in the Garhwal region of the Himalayas in India. The lake is fed by the snowfall over Thalay Sagar (6,904m), Meru (6,672m), Bhrigupanth (6,772m) and other surrounding peaks, and is the source of Kedar Ganga, which in Hindu mythology is considered to be Shiva's contribution to Bhagirathi (a source-stream of the Ganges).
Kedartal, at a distance of 17km from Gangotri, is a popular trekking destination. Starting from Gangotri the route involves a steep rocky climb along the narrow Kedar Ganga gorge en route to Bhojkharak, 8km away. From there it's 4km to the next available camping site of Kedarkharak, and a further 5km to Kedartal. The route passes through scenic Himalayan birch forests, but is made hazardous in places by falling rocks, high altitude and segments of steep ascent.
