The 16-day annual arduous pilgrimage to the glacial-fed Manimahesh lake in Himachal Pradesh began on Saturday.
The authorities are expecting over 500,000 devotees to take part in the pilgrimage, an official said.
The pilgrimage dedicated to Lord Shiva is considered as arduous a trek as the one to the Amarnath cave shrine in Jammu and Kashmir.
"The first official batch of the devotees left for the lake this morning (Saturday). We are expecting over 500,000 devotees to perform the pilgrimage this time," a government official associated with the pilgrimage told IANS.
Every year, the pilgrimage begins on Janmashtami, the festival celebrating Lord Krishna's birth and concludes on Radhashtami (the birth of Lord Krishna's companion Radha).
This year, it will conclude on September 21.
