Reeth is about 12 miles from Richmond, (the North Yorkshire one!) On entering the village there is plenty of parking in the centre of the village (honesty boxes) and from there it is a couple of minutes walk along the road signposted to Barnard Castle. Pass the Buck Hotel on your left, walk past the former Reeth Garage, and the Hall is the next building on the left.
The postcode is DL11 6QT but if you are using a SatNav please also use a street map for reference or you are likely to end up in the workshop complex at the rear of the building.
