Rangitoto Island is a volcanic island in the Hauraki Gulf near Auckland, New Zealand. The 5.5 km wide island is an iconic and widely visible landmark of Auckland with its distinctive symmetrical shield volcano cone rising 260 metres (850 ft) high over the Hauraki Gulf. Rangitoto is the most recent and the largest (2311 hectares) of the approximately 50 volcanoes of the Auckland Volcanic Field. It is separated from the mainland of Auckland's North Shore by the Rangitoto Channel. Since World War II it has been linked by a causeway to the much older, non-volcanic Motutapu Island.
There are several daily ferries to the island from Auckland's main ferry terminal, currently run by Fullers. These allow day trips for the fit to walk to the summit and back, with stunning views of the harbour and city. An alternative to walking, a land train, co-ordinated with the ferry sailings, takes visitors to a short way below the summit. Accommodation on the island is limited to a small number of dwellings near the wharf, one of which is available for public hire. There are no campsites on the island, though there is camping at Home Bay on the adjacent Motutapu Island.
There are virtually no streams on the island so plants rely on rainfall for moisture. It has the largest forest of pōhutukawa trees in the world, as well as many northern rata trees. In total, more than 200 species of trees and flowers thrive on the island, including several species of orchid, as well as more than 40 types of fern.
