I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission not required.
Nearby free parking available at the Nendrum Monastic site (a 4 minute walk away). Good views over Strangford Lough.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 14/09/2021. It remains the responsibility of any pilot to check for any changes before flying at the same location.
