I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission not required.
A stunning and innovative visitor centre built on a former landfill site, with superb views over Mucking Flats SSSI and the Thames Estuary (SPA). Footpaths and cycle ways in 120 acres of nature park, which will expand to 845 acres. Great birdwatching, insect watching and ship watching.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 08/12/2023. It remains the responsibility of any pilot to check for any changes before flying at the same location.
