Tunnel Beach is a locality 7.5 kilometres (4.7 mi) southwest of the city centre of Dunedin, New Zealand.
Located just south of St Clair, Tunnel Beach has sea-carved sandstone cliffs, rock arches and caves.
[2] Local legend says that one or more of Cargill's daughters drowned while swimming at the beach, but there is no truth to this story.
Originally a simple slope, concrete steps were added when it was opened to the public in 1983.
Swimming is not recommended at Tunnel Beach due to a rip that makes it dangerous.
