I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission requirements unknown.
A surreal location with unknown history.
A fairly short walk from Port Eynon beach car park but easily missed as it sits beneath the clifftop. Just a 150 yds to the left theres also a cave known as smugglers cave (can be found on google maps)
Entry from beneath is possible but only during low tides so please be mindful. One inside, there's a climb to the first opening which is not easy so wouldn't recommend it but if your confident and able, a unique place to visit and capture.
Would definitely recommend visiting with a buddy for safety matters.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 13/09/2020. It remains the responsibility of any pilot to check for any changes before flying at the same location.
