Bhutan is an all season destination but when it comes to trekking Spring and Fall (autumn) are best time. There are low altitude trek that are best explored during winter months. Be it spring or autumn the trekking trail are markedly less busy making it great time to visit.
Spring starts from beginning of March till end of the May. Spring has less clear weather but trekkers will surely enjoy the greenery and the landscape carpet in myriad of wildflowers. It is a perfect time to see the wildlife coming out from its hibernation.
Autumn begins from September till end of the November and is the most popular time of the year for trekking. The weather is generally warm and with clear sky which turns to offer the spectacular view of the Himalayan mountain peaks.
