The Barons Cave is one of the oldest show caves in Britain, and visitors to Reigate have been exploring it since the 1700s at least. They run under the grounds of the town's ruined Norman castle, and it’s thought they date from the 11th century. Today the caves are managed by Wealden Cave and Mine Society and open on selected days during the summer. Lantern-lit tours last 20 to 30 minutes.
