I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission requirements unknown.
Decided to take a trip out to Hayling Island after seeing a post about flying over the Oyster Beds. You can park in the Billy Trail Car Park https://w3w.co/marathons.horns.playoffs then a 10min walk along the Hayling Billy Trail, when you get to https://w3w.co/outbound.relocated.graceful take a right and it walks along the water front. There are numerous areas on the edge of the water front with the public footpath running behind with clear areas to fly but also able to keep an eye out for walkers. Depending on the season, there might be birds nesting in the area.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 09/12/2020. It remains the responsibility of any pilot to check for any changes before flying at the same location.
