Tunnel Beach is on the Otago Peninsular and only a stones throw from the city of Dunedin. For centuries the great southern ocean and its salt-laden winds have sculpted the sandstone coastline south of Dunedin, typically resulting in high cliffs, arches and headlands that provide endless vantage points for breathtaking views as the ocean continues its relentless artistic assault.br/br/Beyond the beauty of the rugged sandstone cliffs, the claim to fame of Tunnel Beach is the tunnel down to the beach that a local politician had commissioned for his family back in the 1870s. Access to the beach is via a track that descends to the top of the cliffs, before venturing though the dimly lit tunnel a further 72 steps to the beach.
