I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission not required.
Free parking at Portballintrae car park, where there is a shop and public toilets. The River Bush enters the Atlantic Ocean here at Runkerry beach. Giant's Causeway and Bushmills are a short drive away.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 27/09/2021. It remains the responsibility of any pilot to check for any changes before flying at the same location.
