I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission not required.
Donaghadee is a picturesque seaside town on the Co. Down coast. The harbour Bicentenary was in 2021. There is free parking all the way along the promenade and a large car park near the pier. Cafés, restaurants, pubs and toilets are all within easy walking distance.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 28/09/2021. It remains the responsibility of any pilot to check for any changes before flying at the same location.
