I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission requirements unknown.
Park in the Newborough Woods car park (£5 and worth every penny), walk up the beach to the island. Fly skirting the island over to the lighthouses and also along the beach. Amazing scenery, beautiful woods and beach. Snowdonia in the background (very hazy when I flew). Woods have many red squirrels if you have the time.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 17/09/2020. It remains the responsibility of any pilot to check for any changes before flying at the same location.
