Every year, thousands of devotees trek to a cave in Jammu and Kashmir.

The journey begins in Jammu and the destination is the Amarnath cave, about 400 km away. The last 45 km, from Pahalgam, is covered on foot.

The five-day journey to the cave shrine, dedicated to Lord Shiva and located 3,800 metres (12,800 feet) above sea level, is arduous.
