I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission requirements unknown.
Barton's Point Coastal park on the Isle of Sheppey. Small amount of parking near entrance. More parking available in boating lake when it's open.
During the winter, it's a quiet open area with pedestrians and dogs intermittently but borderline rare in the winter months.
Would not recommend this location in the summer months as it will be extremely busy.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 12/01/2022. It remains the responsibility of any pilot to check for any changes before flying at the same location.
