Trekking in Bhutan can be completely a different experience if you compare it to trekking in Nepal. While in Nepal, almost every trekking route has an extensive network of teahouse and lodges to feed and accommodate tourists, Bhutan has very few to no teahouses on the trails and has almost no tourist infrastructure at all. This exactly could be a reason why you would want to trek in Bhutan.
For Bhutan has adopted a rather guarded approach to tourism in Bhutan with an intention of avoiding negative impact on the country's environment and culture, proper preparations and arrangements are must before you travel to this cultural kingdom.
Trekking in Bhutan can become one of the best ways to experience the exotic mountains and landscapes. The rugged terrain passing through the stunning array of mountains and valleys and sightings of world's rarest biodiversity in a delicately preserved environment is certain to leave a long lasting impression.
Thanks to Bhutan's protected approach to tourism, treks here are highly exclusive and trekkers will join the Yak herders and local villagers on the trails. From a simpler one-day hiking to the more robust multi-days treks, Bhutan has adventure-travel activities suiting everyone's interest and personal preferences be it experiencing the natural, or religious, or traditional or architectural marvel (or even better, all of them).
