Winter is a good time for touring in western Bhutan, bird watching in the subtropical jungles in the south, and white water rafting. The days are sunny and cool but it's quite cold once the sun sets. From December to February the road from Thimphu to Bumthang and the east may be closed because of snow for several days at a time. It would be best not to plan to visit these regions at this time.

In recent years overcrowding has become an issue during the major tsechus (Buddhist festivals) at Thimphu and Paro, which coincide with the best seasons. You stand a much better chance of getting flights, accommodation and probably a more intimate and rewarding festival experience if you schedule your trip around one of the other cultural events.

Other part of the landscape mostly flat plains or gently rolling hills in north and west; remainder is mountainous, especially Pyrenees in south, Alps in east. And national park in the south Bhutan is splendide where we can see all the animal inside the forest as well as Nepalese origin's festival during the 'Dashain' and 'Deepawali' makes southland bright night druring this period of festival.
