Manimahesh is in the south-eastern corner of Chamba District of Himachal Pardesh here in north India. It lies at an altitude of 13,390 ft.
The name Manimahesh signifies a jewel (Mani) on Lord Shiva's (Mahesh's) crown Local people claim that the moon-rays reflected from the jewel can be seen from Manimahesh Lake on clear full-moon nights (which is a rare occasion). It is more likely to be the light reflected from the glacier that adorns the peak, like a serpent on Shiva's neck.
It is believed that Lord Shiva one of the three Lords in Hindu Trinity (known as Lord Brahma the creator, Lord Vishnu the Preserver and Lord Shiva the destroyer) stays at Manimahesh Kailash.
Offical Manimahesh yatra starts near janmashtami festival and continue till mid september. For rest time of year, this whole area is covered under snow.
