One of the largest of Ladakh&rsquos gompas, Hemis, was founded in the 1630s under the patronage of King Sengye Namgyal. It is possibly the largest and richest of the Ladakhi monasteries. Its du khang, shrines, maze-like stairs and courtyards, and rooftops are all worth exploring. Travel down the Indus on the Leh-Manali Highway until Karu. Cross the river, and after numerous loops and twists, as well as countless fields and poplar trees, the vast and stunning Hemis Gompa comes into view, nestled away in a cleft of the Zanskar Range. The annual Hemis Festival, which takes place in June or July, has made the gompa particularly well-known. The two-day event honouring Guru Padmasambhava features monks wearing masks and dancing at a hypnotic, slow pace to the rhythm of cymbals and long horns.
