Here are the rules for operating drones in Bhutan.
In Bhutan, all drones must be approved before operation at the Bhutan Civil Aviation Authority (BCAA) at Paro International Airport. However, the approval is granted only to governmental organizations. Thus it is not allowed to operate drones as a traveller. If you can somehow get the permission, the following rules apply.
Maximum flight altitude: In Bhutan, your drone is not allowed to climb higher than 90 meters (300 feet) above ground or the water surface.
Maximum horizontal distance and FPV: Bhutan allows the operation of drones only within the visibility.
Compulsory insurance: In Bhutan, it is required by law to insure your drone.
Maximum take-off weight (MTOW): Your drone cannot weight more than 6 kilograms.
Distance to airports: You must guarantee a distance of 5 kilometers (3 miles) to airports at any time.
Other safe distances: No further safety distances are defined so far.
Flight bans: In Bhutan, you cannot fly over yellow roofs (religious buildings).
Regulations for commercial pilots: Currently, there seems to be no distinction between private and commercial flight manoeuvres.
