I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission not required.
Reckoned to be the longest waterfall in England.
Car park at ///blissful.boosted.mole it is free but there is a voluntary fee for the upkeep should you choose to contribute you can do with cash or a pay by phone app.
Once you have parked it is a 30 minute walk (at a reasonable pace) to the waterfall and the reservoir retaining barrier. Be careful as the rocks alongside the waterfall can be slippery!
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 16/11/2022. It remains the responsibility of any pilot to check for any changes before flying at the same location.
