I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission requirements unknown.
Park in layby at edge of the road, then a short walk down the bridle path to the river.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 04/08/2022. It remains the responsibility of any pilot to check for any changes before flying at the same location.
