When to Visit Bhutan
The best seasons to visit Bhutan are during Spring (March, April & May) and Autumn (September, October & November). The major bhutanese religious festivals are held during these seasons and fine Spring and Autumn weather makes it an ideal time for trekking in Bhutan and for traveling throughout the country enjoying great views of Himalayan mountains peaks.
Nevertheless, it is possible to visit Bhutan throughout the year as Bhutan has 4 seasons in a year and each season has its own charm as given below:
Spring Season-March, April and May
In Spring the trekking season commences in moderate altitudes. Above 3000 metres spectacular rhododendron forests bloom. It is also the perfect time for a rafting tour. In Paro, one of the largest monastic festivals – Paro tshechu takes place.The temperature is pleasantly mild even up to the Alp regions. Rain comes only in May as the harbinger of the approaching monsoon.
