I have just added this to the map of places to fly your drone at Drone Scene:
Bwa Gwyn (the white arch) is a sea arch on the cliffs between Rhoscolyn and Trearddur Bay, Anglesey. There is a footpath allowing you to stand on top of the arch if you’re brave enough. To the north is another sea arch called Bwa Du (the black arch)
Nb - this site is less than half a mile outside RAF Valley FRZ, and is an active area for military helicopter training. When I was there I had to abandon my flight because a helicopter decided to practice landing on the neighbouring headland
