T.g. Longstaff and Frank Smythe discovered, for the outside world, this enchanting place by chance in 1931. Though the local villagers of Bhundar Valley knew it as andankanan since time immemorial. They feared to venture into the valley, because of the spirits and fairies that were thought to be haunting the beautiful valley. They feared that the spirits would carry them away. More than thousand varieties of flowers, ferns, and Himalayan herbs grow in the valley. The most beautiful of all Himalayan flowers, the blue Primula can be seen blooming in thousands in the valley. The best time to see the valley in full bloom is from mid-July to mid-August.To reach the valley one has to trek from Govind Ghat, on the route to Hemkund Sahib, up to Ghangaria, 12 kms ahead.Few furlongs ahead of Ghangaria the trek route to the valley takes a detour towards left. The valley is about 5 kms from Ghangaria.
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. Encircled by seven snow clad peaks and their associated glaciers, it reflects its surroundings enchantingly on its crystal clear serene waters. The glaciers from Hathi Parvat and Saptrishi peaks feed the lake and a small stream called Himganga flows out of this lake. As alluded to, in the holy Granth Sahib, 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).
The five K's' date from this period: kesh (uncut hair) kangha (comb), kirpan (dagger or short sword), kara (steel bangle), and kachh (boxer shorts). The most important is the uncut hair, adopted before the other four. The comb is sometime designated specially as wooden. The dagger and the shorts reflect military influence, while the bangle may be a from of charm.
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.
Despite its ancient connections, Hemkund/Lokpal was discovered by a Sikh Havaldar, Solan Singh and became a major pilgrimage center only after 1930.
