Every season has its own Charm. However, the most popular times to visit Bhutan are the spring months of March, April & May and the fall months of September, October & November.
Traveling to Bhutan during the months of December, January, February and June are also equally recommended since the weather is still good with clear blue sky during winter that allows you to enjoy the stunning views of the snow-clad mountains and during June the weather is warm with very little rain and lush green valleys. You will experience very less visitors that also mean better service at better price.
