I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission requirements unknown.
Car parking is £3 for 4 hours. Not sure if permission is required but I just went into the shop / water sport center and asked the manager if it was allowed. Friendly people and no problems flying. Be careful about half way up the lake I got signal interference warnings. Did not seem to affect flying though.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 11/09/2020. It remains the responsibility of any pilot to check for any changes before flying at the same location.
