September - October, and February to June are in general good months to visit Bhutan. Winter comes to Bhutan a little early and peak winter months of Nov to Jan although doable, are not highly recommended. June to mid Sept is the rainy season and though no weather should hold off the intrepid traveller, you might want to plan around that as well.
Weather is different in low-altitude areas (where it is more subtropical), than those places up in the hills where it varies from cool to severely cold.
How to reach Bhutan
Visa: Getting into Bhutan obviously requires a visa , and other than India, Bangladesh and Maldives nationals, the visa has to be applied-for from the Bhutan government at least 30 days in advance of your travel dates. The visa is stamped on arrival if your tour/visa application has been approved, so there is no need to visit the embassy itself. You can ask your travel operators to get the visa for you, or try getting it yourself. The visa is issues for 14 days, extendable once though.
Tour packages: For all travellers from countries other than above, it is mandatory to buy a tourist package to be eligible for the visa.
