A very recognizable spot - it's the remains of a former Sulphur mining operation on the volcano White Island, a great day trip from Whakatane (pronounced Fuck-a-Tannay!) - definitely recommended if you're on the North Island.
Fun fact: the crater lake is one of the most acidic in the world, ~pH 1 - boiling Sulphuric acid, yay!
