I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission requirements unknown.
A powerful if short waterfall, which often has Salmon leaping (May to October) and is located in a picturesque area.
Free car parking at the Falls of Shin Centre - currently closed and no loos either - and a short walk down to the viewing area - reasonably steep but not too taxing and with good access for all. The falls are in the bottom of a steepish sided valley, and are surrounded by trees, so watch your flightpath and take care.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 28/04/2023. It remains the responsibility of any pilot to check for any changes before flying at the same location.
