A short 25-minute cruise through the Waitemata Harbour to the Hauraki Gulf delivers you to Rangitoto Island. Rangitoto Island is the largest and youngest of the many volcanoes that make up the Auckland volcanic field. It erupted around 600 years ago, but is extinct now and safe to explore. During your cruise to and from the island enjoy fantastic views of Rangitoto Island and Auckland the 'City of Sails'. On reaching the island you can walk to the summit (1 hour direct) for great views of the Hauraki Gulf and over Waitemata Harbour looking back towards Auckland. There are a number of walking trails to explore this volcanic island, further information can be found at the Department of Conservation website.
