 To the south is the deep wooded valley of Lyncombe Vale.This was formerly the route of the Bath branch of the Somerset and Dorset Railway, and the Combe Down Tunnel which at 1700 metres in length was reputed to be the longest unventilated rail tunnel in Britain.This tunnel, together with the shorter Devonshire Tunnel, were both reopened as part of the Two Tunnels Greenway on 6 April 2013 forming part of the National Cycle Network NCR244.
