With great altitudinal variations, weather is quite mixed in Bhutan. So be prepared to face the unforeseen weather conditions.
We expect visitors to dress modestly and respectfully especially if you are planning a visit to the monasteries, Dzongs and other religious institutions. Long pants and long sleeved tops should be worn when visiting such places. As a mark of respect, be kind enough to remove your hats, caps etc. as you enter religious and administrative premises, institutions and in any other place that you come across with the national flag being raised.
