I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission not required.
Castle Varrich, in Tongue. Good parking at trailhead for about a dozen vehicles - less if RV - and a good mile walk to the castle, firstly down the hill to a bridge at sea level, then up through a woodland to the Castle at about 500ft up - path is decent and plenty of benches to stop and take in the view - or recover!
It was very windy in the day I visited, on the limits of the MINI3Pro, but definitely worth the walk!
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 09/04/2023. It remains the responsibility of any pilot to check for any changes before flying at the same location.
