I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission requirements unknown.
The Fairbourne Railway (Welsh: Rheilffordd y Friog) is a 12+1⁄4 in (311 mm) gauge railway running for 2 miles (3.2 km) from the village of Fairbourne on the Mid-Wales coast, alongside the beach to the end of a peninsula at Barmouth Ferry railway station, where there is a connection with the Barmouth Ferry across the Mawddach estuary to the seaside resort of Barmouth (Welsh: Abermaw)
Car park on beach road £3 for 6 hours or you can park free of charge at the Barmouth ferry end.
The marker is the location of the railway station but would recommend standing on the corner by the beach to get fantastic coastal scenery shots as well.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 29/08/2021. It remains the responsibility of any pilot to check for any changes before flying at the same location.
