Land owner permission requirements unknown.
Knipe Point and Cayton Cliff are National Trust owned property, except for the beach. Car parking is available at the top of the cliff, and there is a very steep stepped footpath leading down to the beach area.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 30/01/2022. It remains the responsibility of any pilot to check for any changes before flying at the same location.
