I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission not required.
About a mile uphill walk - a moderate climb in a couple of places - from the car park / layby (layby is free parking - and you find yourself at the bottom of this series of waterfalls, that drain into Lake Vrynwy.
It is not overly popular but there are a few folks coming and going - they don't tend to hang around more than 10 mins though.
Great cinematic views and some lovely twisty and tight FPV flying up the falls themselves, although not vertical enough for any real 'diving'… AVATA2 coped well, but do watch out for the branches…
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 04/01/2025. It remains the responsibility of any pilot to check for any changes before flying at the same location.
