The Best Things to Do in Ilfracombe, Devon
"The idea of going to a beach to swim in a pool might seem unusual, but Tunnel Beach is odd in many ways. The name comes from the fact that you have to walk through tunnels dug by the Victorians to reach the beach itself. On arrival, you can either swim in the sea proper or a specially sectioned off sea-water pool, which is a great option for choppy days."
