The last of the Himalayan Kingdoms, Bhutan, offers a trekking experience like nowhere else on earth. This is where tranquility and natural beauty combine into what many consider trekking perfection. The eastern end of the Himalaya chain forms Bhutan’s northern border with China (Tibet) before it enters the wild and untamed wilderness of Arunachal Pradesh. Bhutan feels like a final frontier, where immense forests buffer and protect against potential invaders and where the mountains are both spiritual inspiration and a life sustaining resource.
By far the most popular trekking routes in Bhutan are the Chomolhari Trek and the route via Lingshi or Ghasa to Laya. The connecting trail to the Snowman Trek is less popular but expect to see other trekkers throughout the region in the main season. None of these routes is difficult but you should be beware of altitude sickness as there are quite a few rapid ascents.
The trail from Bumthang to Lunana (Thanza) is the toughest section of the GHT Bhutan and covers the majority of the famous ‘Snowman Trek’. Some trekking companies describe this route as the toughest trek in the world, but it isn’t, not by a long shot. However, it is committing and very tough for pack animals, which perhaps explains the relatively high failure rates of groups that attempt this route.
The eastern valleys of Bhutan are wild and sparsely populated. The trails that link the main north-south valley systems are now overgrown and rarely used as locals prefer to take the longer road route instead of walking. The route over the D**g La is particularly difficult and hard to navigate. Although a little higher the Rodung La trail is in far better condition.
