I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission requirements unknown.
240ft waterfall next to a cafe and car park - £5 for the day, good cake and tea too. The waterfall can be seen from the bottom and the top can be reached by a steep mile walk. No issues flying the drone as long as you are respectful of other people in the area.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 08/10/2022. It remains the responsibility of any pilot to check for any changes before flying at the same location.
