This three day trek is beautiful for nature loving people, as it provides wide range of flora and fauna; birch, juniper, blue pine, maple, hemlock and different species of rhododendrons. On the trek, one would get to encounter pheasants and Himalayan black bears, which demands cautiousness. Along the trek, there are Buddhist temples to offer your prayers for self and sentient beings. Walking along the ridge sometimes offers panoramic view of Mt. Gangkar Puensum, the highest peak of Bhutan, on clear days. The best time to go on this trek is in spring when rhododendrons are in bloom. A pin drop silent night would be lifted with hooting of owls at the first camp site; hence the name ‘Bumthang Owl Trek’. The trek starts from Choekhor valley and ends in Chumey valley in Bumthang.
