There are approximately 53 volcanoes in Auckland, which have over thousands of years produced an array of interesting lagoons, tuft rings and lava flows in Auckland city. The biggest, most active and most visible volcano – Rangitoto sits on an island of the same name in Auckland harbour.
This has erupted repeatedly over the past thousand years, with ash clouds and lava flows lasting for several weeks to years. It’s the only volcanic eruption here witnessed by humans. This exciting and dynamic landscape lends Auckland its unique features including mound like hills all over the place which provides ample places for nice picnics, photo-ops and so on.
