The monastery of Stongdey lies 18 kms. To the north of Padum, on the road leading to Zangla. An old foundation associated with the Tibetan Yogi, Marpa, Stongdey is now the second largest monastic establishment of Zanskar, inhabited by the resident community of about 60 Gelukpa monks. The sprawling whitewashed complex has a number of temples, each a repository of the region's rich monastic legacy. Stongdey can be reached by foot in about 4 hours along the recently laid rough road. The climb up to the monastery is rather strenuous, but it is worth the trouble for the breathtaking scenery of the valley available from here.
