I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission not required.
Nearest car park is Berners Close pay & display in Grange.
Although close to the railway it’s infrequent & any train can be clearly seen/herd. Plus you can access the shore & take off no problem.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 25/04/2021. It remains the responsibility of any pilot to check for any changes before flying at the same location.
