The Surrey town of Reigate is well known for its 'caves' which riddle the town centre, although these are in fact largely old sand mines. The castle mound overlooking Reigate town centre is composed of soft sandstone and has been mined over several centuries. The castle has long gone but the mound and many of its excavations still remain. Known locally as the "Reigate Caves", tours include the Barons' Cave in the Castle Grounds and the East and West Caverns in Tunnel Road. Your view of Reigate will change once you have experienced what lies beneath your feet!
