There is a turning on the way to the museum, which had a small signpost when I last went up there. Alternatively, as you come out of the museum / restaurant, turn right, at the end of the carpark take the first left & walk down the hill & back up again, go into the driveway & you're there. Usually, a black labrador cross will come rushing to meet you & take you back to his home, problem is he likes to see you off the premises too & has to be persuaded to go back.
