I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission not required.
As far as I can ascertain this area is free to fly in. However just a few miles to the west is Cardiff Airport so be aware
I TOAL from a public grassed area at 51.392444, -3.265968
No public involvement at all, just the occasional dog walker on the path. I flew on a Friday afternoon.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 04/03/2022. It remains the responsibility of any pilot to check for any changes before flying at the same location.
