You can arrange to visit the active volcano White Island from any city in the Bay of Plenty. Tours require you to wear a hard hat. Exciting stuff!
White Island (Whakaari) is the perfect example of an active volcano. It breathes, it roars and it hisses from steaming vents releasing 800°C toxic gases. Situated off the coast of Whakatane, it has had around 35 small to moderate eruptions since 1826. The Maori name for the island is 'Te Puia o Whakaari', which means 'the dramatic volcano'.
On an eruption scale of one to five, the island is usually on an alert level of one or two. In March 2000, three small vents appeared in the main crater and began belching ash which covered the island in fine grey powder. An eruption later that year blanketed the island with mud and scoria and a new crater appeared. At most times the volcanic activity is limited to steaming fumaroles and boiling mud.
Although it's privately owned, White Island is a scenic reserve that can be visited by launch or helicopter. From Whakatane, Rotorua and Tauranga you can arrange a walking tour of the island, which leads right into the huge main crater. Hard hats and gas masks are provided for the tour - it's an extraordinary experience.
A surprising sight is the remains of a sulphur mining operation. Several attempts were made to mine sulphur on the island, but mining came to a sudden halt in September 1914, when a mudslide killed all the workers. They disappeared without trace; only the camp cat (named Peter the Great) survived.
