While the Rodung La Trek does not ascend to very high altitudes, it is still fairly challenging as the trail covers some fairly steep climbs and descents. The trail takes you from Bumthang in Central Bhutan to Trashiyangtse in the far eastern reaches of the kingdom.The route was once an important trade road in the past but has fallen into disuse now and is chiefly used as a hiking trail. The trail passes through alpine and bamboo forests, meadows and mountain passes, through villages and temples offering hikers an incredible array of biodiversity to appreciate. The Hike typically takes 10 days to complete and is best carried out in winter between October-Early November or in spring between April-Early May.
