Amarnath Cave, one of the holiest Hindu shrines, houses a Shivaling formed naturally from ice and is a major pilgrimage site for devotees of Lord Shiva. The cave is open only during the Shravan month (July-August) and can be reached via two routes, Baltal or Pahalgam. Sonamarg sits on the Baltal route, which is shorter but steeper, making it the starting point many pilgrims use for the trek.
The shrine, dedicated to Lord Shiva, is almost 5000 years old. It holds an important place in Hindu Mythology. Inside it is an ice stalagmite which resembles Lord Shiva and waxes during the months of May to August. The water seeps into the rocks and soon wanes after that. It is believed to be the place where Lord Shiva explained his consort Goddess Parvati about the secrets of life and eternity.
There are two other ice formations which represent Goddess Parvati and Lord Shiva's son Lord Ganesh. People visit here during the Shravani Mela which is a 45 day season in July-August. It takes five days for the devotees to reach the destination on foot from either Srinagar or Pahalgam.
