The best time to visit Bhutan is during spring (March to May) and autumn (September to November). These seasons offer clear skies, vibrant festivals, and ideal trekking conditions. Spring showcases blooming rhododendrons, while autumn features the popular Thimphu Tshechu festival. Avoid the monsoon (June to August) due to heavy rains and winter (December to February) for extreme cold. https://www.captureatrip.com/blog/best-time-to-visit-in-bhutan
