MUSTANG, the ancient Himalayan kingdom
The dream of every trekker of the Himalaya. This ancient kingdom opened to trekkers in 1992. Located on the Tibetan plateau to the North of Dhaulagiri and the Annapurnas the region is barely affected by the monsoon.

GST has strong links with the region. Long before the opening in 1992 we had already trekked in the area by foot and horse and later on pioneered several itineraries.

Up to recently, trekking in Mustang could only be done by camping in tents, however GST collaborated with ICIMOD to help develop home stays and lodges so that the villagers benefited directly from the trekkers.

To this day we remodel our itineraries to include excursions like the Chungsi cave, Drakmar’s crest, Lo Gekar , the Choser valley and the hidden stupa of Lori.

Following Paulo Grobel we organised high altitude treks between the Nar valley and Mustang with expeditions close to the tibetan border.
