Land owner permission not required.
I parked in the car park below Manorbier Castle which normally costs, but the machines are currently out of order. You can access the beach and castle from the car park, on a couple of minutes walk away.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 29/11/2021. It remains the responsibility of any pilot to check for any changes before flying at the same location.
