The high altitude Lokpal lake, known as Hemkund ( 4329 mts.) lies in heavenly environs. A steep trek from Ghangharia leads one to this spot in about four to six hours. It is an important pilgrimage for both Hindus and Sikhs, as well as for people from other faiths. There is a Sikh Gurudwara and a Lakshman temple built on the bank of the lake. It is believed that Lakshman, the younger brother of Ram, meditated by the lake and regained his health after being severely wounded by Meghnath, son of the demon Ravana, during battle. Guru Govind Singh, the tenth Guru of the Sikh faith had meditated on the bank of this lake in one of his earlier births. It is widely believed among Sikhs that Guru Govind Singh introduced the features now universally associated with Sikhism. On 15th April 1699, he started the new brotherhood called the Khalsa (meaning the pure, from the Persian word 'Khales') an inner core of the faithful, accepted by baptism (amrit). Despite its ancient connections, Hemkund/Lokpal was discovered by a Sikh Havaldar, Solan Singh and became a major pilgrimage centre only after 1930.
