I have just added this to the map of places to fly your drone at Drone Scene:
Pen-y-crug is a hill in the Brecon Beacons National Park. It is commonly referred to as simply 'The Crug' (which signifies 'top of the mound' in Welsh).
On its summit is one of the most impressive iron age hillforts in the National Park
Its flat trig point on the summit at 331m overlooks the valley of the River Usk to the south. To the southeast are panoramic views over Brecon whilst eastwards are the Black Mountains and south the Brecon Beacons.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 10/04/2025. It remains the responsibility of any pilot to check for any changes before flying at the same location. Landowner permission may be required before taking off.
