I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission requirements unknown.
There's a car park (with honesty box) near the Buxton Caravan Club site. Toilet facilities here. Short but quite steep walk up to the tiny "castle". 360 views all around.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 22/12/2020. It remains the responsibility of any pilot to check for any changes before flying at the same location.
