Undoubtedly one of the toughest treks in the world, the Snowman Trek starts from Laya into the high altitudes of the Himalayas. The Trek takes tough and enduring trekkers into Lunana region and further on to Gangkhar Puensum and Bumthang or down to Sephu in Wangdue, depending on the route. Trekkers have to camp above 5000m more than once.
