I have just added this to the map of places to fly your drone at Drone Scene:
Land owner permission not required.
Located within Northumberland National Park who have a sensible drone policy, road signs are not very good not sure if Sat Nav will get you there, nearest named location is Langleeford NE71 6RG…A beautiful tranquil valley ideal for a picnic, the road in is a bit rough in places and you may need to negotiate a small ford en-route, limited parking appears very popular for walkers possibly heading for "The Cheviot" nearby.
The originator declared that this location was not inside a Flight Restriction Zone at the time of being flown on 07/06/2022. It remains the responsibility of any pilot to check for any changes before flying at the same location.
