I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission not required.
Attempted to go to snowdon but failed, so parked the car on the side of the road and took of from halfway down Llanberis pass, plenty of take off points, can get busy for parking at peak times
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 25/07/2021. It remains the responsibility of any pilot to check for any changes before flying at the same location.
