I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission obtained.
There is a parking area just after the entrance paypoint, if you or somebody with you is disabled tell them, they will then have the gates opened for you to drive all the way up to the castle
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 20/07/2020. It remains the responsibility of any pilot to check for any changes before flying at the same location.
