I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission requirements unknown.
Park on Nelson Road and walk down to the river path.
This particular marina has nothing else nearby to note. However a couple of miles north up the path is Danter's Treasure Island Amusement Park which is basically a static fun fair. I'd advise driving up and parking there, which is £1 per hour.
There's also other more fun things to do in the main park such as crazy golf, boat rides and other fun activities for younger kids. Main Stourport Town Centre also has lots of lovely shops should you visit during open hours.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 07/08/2022. It remains the responsibility of any pilot to check for any changes before flying at the same location.
