I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission requirements unknown.
Coming from the mainland drive about half a mile south from the bridge and just after the Esso Garage on your right turn right down the unmade road. There is a car park at the end. Notice boards will give you a brief introduction to the wildlife to be expected in the area.
The oyster beds are what remains of a once thriving industry. An attempt to revive it in the 80's seems to have been a scam allowing 800,000 tons of rubble to be dumped in the harbour (see link below)
The area is just off the popular Hayling Billy Trail which begins at the old station 4 miles south and continues northward to the remains of the old railway bridge. It is popular with both casual and serious walkers and cyclists.The area is a nature reserve so fly responsibly
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 22/10/2019. It remains the responsibility of any pilot to check for any changes before flying at the same location.
