A cave situated at an altitude of , about 168 km from Anantnag city, the district headquarters, from Srinagar, the summer capital of Jammu and Kashmir, reached through either Sonamarg or Pahalgam. It is an important shrine of Hinduism. The cave, located in Sind Valley, is surrounded by glaciers, snowy mountains and is covered with snow most of the year, except for a short period in the summer, when it is open to pilgrims. In 1989, pilgrims numbered between 12,000 and 30,000. In 2011, the numbers reached a peak, crossing 6.3 lakh (630,000) pilgrims. In 2018 pilgrims numbered 2.85 lakh (285,000). The annual pilgrimage varies between 20 and 60 days.
The Amarnath cave, abode of the Mahamaya Shakti Pitha, is one of the 51 Shakti Pithas, the temples of the Indian Subcontinent that commemorate the location of the fallen body parts of the Hindu deity Sati.
The Shiva Lingam at the shrine is a Swayambhu lingam. The lingam is a natural stalagmite formation inside a tall cave at an elevation of on the Amarnath Mountain, which has a peak of . The stalagmite is formed due to the freezing of water drops that fall from the roof of the cave onto the floor, resulting in an upward growth of an ice formation. Here, the stalagmites considered as the lingam, a physical manifestation of Shiva, form a solid-dome-shape. Two smaller stalagmites are thought to represent Parvati and Ganesha.
According to the ancient Hindu texts of the Mahabharata and Puranas a lingam represents Shiva. The lingam waxes during May to August, as snow melts in the Himalayas above the cave, and water seeps into the rocks of the cave; thereafter, the lingam gradually wanes. Religious beliefs hold that the lingam grows and shrinks with the phases of the moon, reaching its height during the summer festival. Hindus believe this is the place where Shiva explained the secret of life and eternity to his divine consort, Parvati.
