I have just added this to the map of places to fly your drone at Drone Scene - Location # 590
Land owner permission requirements unknown.
There are two carparks nearby (satnav KA7 4JT), but there is a walk along the beach with a scramble down a drop of a few feet from the carpark. A fairly popular beach so be prepared for people walking past (I headed straight out to sea and mostly stayed there). The area is outside the Prestwick FRZ, but on the flight path for light aircraft so keep your eyes peeled and be prepared to land.
The originator declared that this location was not in a flight restriction zone at the time of being flown. It remains the responsibility of any pilot to check for any changes before flying the same location.
