I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission requirements unknown.
Close to St Osyth & Martello Beach Holiday parks.
Not far from Clacton Aerodrome which isn't in an frz but extra vigilance is advised.
Also can be very windy.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 28/10/2021. It remains the responsibility of any pilot to check for any changes before flying at the same location.
