What to Bring
There is a 20 kg (44 lb) weight limit (30 kg or 66 lb in business class) on Druk Air. You should hold yourself to this allowance. Even if you pay for excess baggage, it still travels standby and may be offloaded. As with all travel, the less you carry, the easier it is to move about and the less there is to misplace.
There are several things that you should carry to make a trip to Bhutan more comfortable. All of the following items are essential:Pack a folding umbrella; especially if traveling during the monsoons. Rain is possible any time, and is almost certain from June through August. There are occasional electric outages throughout the country; so you should always keep a torch (flashlight) beside your bed.
Carry a pair of sunglasses (as protection from high altitude glare). A Swiss army knife has many uses, such as cutting cheese and opening bottles. Bring a small clock with an alarm to help you wake up, because not all hotel rooms have telephones.
If you are on a cultural tour, it’s OK to bring a hard suitcase, though a soft bag is more versatile and easier to pack into the luggage space of a vehicle. You will also want a small rucksack or waist pack to carry your camera, water bottle and other essentials in the vehicle and when you are walking around town or visiting monuments.
