The large Miramar Peninsula is on the southeastern side of the city of Wellington, New Zealand, at the entrance to Wellington Harbour, in Wellington's eastern suburbs. According to Māori legend, it was formed when the taniwha Whaitaitai beached as he tried to escape the confines of the harbour.
From above, the peninsula resembles the shape of a shark. Northwards, it juts into Wellington Harbour (formerly known as Port Nicholson, and in Māori as Te Whanganui-a-Tara, the Great Harbour of Tara). To the south are Cook Strait and the South Pacific Ocean. The suburbs of Kilbirnie, Lyall Bay, Hataitai and Newtown, and the inner city, lie to the west. To the east a narrow stretch of water connects Wellington Harbour with Cook Strait and the open sea; beyond this channel are the scrubby Eastbourne hills, and the high and forested Orongorongo Ranges. From the peninsula's high points, an observer can look north to the Hutt Valley and the Tararua Ranges, or southwest, across Cook Strait, to the high peaks of the Inland and Seaward Kaikoura Ranges, which are often snowbound in winter.
The peninsula has an area of 800 hectares. The coastline is rocky, with many coves, steep cliffs, and small pinnacles and caves, but there are also sweeping and sandy beaches, notably at Breaker Bay, Worser Bay, Scorching Bay, Moa Point and Tarakena Bay. A high ridge, running on an approximate north/south axis, forms the spine of the peninsula, with high points Mount Crawford in the north and Beacon Hill in the south. The peninsula has a large area of low-lying land, the Miramar flats, and a smaller area of flat land at Seatoun, both of which are mainly covered in residential housing.
