With great altitudinal variations, weather is quite erratic in Bhutan. So be prepared to brace the erratic weather as you step outdoor. We expect visitors to dress modestly and respectfully especially if you are planning a visit to the monasteries, fortresses and other religious institutions. 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.
