Tunnel Beach

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.^[1] The beach's claim to fame is the man-made tunnel dug by local politician John Cargill, son of Captain William Cargill, who had commissioned for his family in the 1870s.^[2] Urban legend states that one or more of Cargill's daughters drowned while swimming at the beach, but there is no truth to this story.^[3]

The tunnel itself is rough-hewn, and still shows the marks of the hand working which created it. ^{[citation needed]}Originally a simple slope, concrete steps were added when it was opened to the public in 1983.

Access to the beach is via the DOC Reserve, and is open year-round, excluding a flood in October 2024 which forced the beach to close until November 2025.^[4] The track is a popular walking excursion. It descends from 150 metres (490 ft) above sea level at its start, a short distance off Blackhead Road, winding for some 1200 metres to the top of the tunnel close to a natural sea arch. The tunnel descends 72 steps to the beach, and is dimly naturally lit.^[5] Note that the path down is steep and can be very slippery following wet weather.
