I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission not required.
I know there are number of other pins in this area but none are showing Hilbre Island as a location.
I would go at low tide as you need to walk out a far way to be close enough to fly.
There is a pay and display car park here ///soon.humans.bibs and a jetty running down the shore here ///winter.interval.thud.
http://www.hilbre-island.co.uk/ here you can find the route if you want walk into the islands.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 05/03/2022. It remains the responsibility of any pilot to check for any changes before flying at the same location.
