I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission requirements unknown.
The iconic Lagangarbh Hut stands to the north of Buachaille Etive Mòr. It is owned and operated by the Scottish Mountaineering Club.
There is a public carpark on the A82, but it's rough going and perhaps not recommended for smaller vehicles. Once parked, a short walk along a path will take you far enough away from the road/carpark and the hut for TOAL, but watch for other people as it's a popular place, particularly with photographers.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 28/01/2023. It remains the responsibility of any pilot to check for any changes before flying at the same location.
