I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission requirements unknown.
Tidal marshland ( though needs a really high tide to be completely covered ) with a few rusting boat hulks
Park in nature reserve carpark at end of Jameson Rd.
Be aware of model flying field at southern side of nature reserve
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 07/10/2020. It remains the responsibility of any pilot to check for any changes before flying at the same location.
