This is a 3 mile walk that takes you up and around Box Hill. Detail of the route and a map can be downloaded here: Walk and Map. Box Hill is a small village right on the western edge of Wiltshire, just a few miles east of Bath. It is indeed situated on a hill, and this circular walk takes you right from the valley floor to the top of this very steep hill. Box Hill is also the location of Brunel's Box Tunnel, which carries the Great Western Railway between Bath and Chippenham.
