Curio Bay

Curio Bay is a coastal embayment in the Southland District of New Zealand, best known as the site of a petrified forest some 180 million years old. It also hosts a yellow-eyed penguin colony, arguably the rarest of penguin species, with approximately 1600 breeding pairs in the extant population. The bay, along with neighbouring Porpoise Bay, is home to the endemic Hector's dolphin. Southern right whales are occasionally observed offshore, as on numerous parts of the country's coast. Located near the southernmost point of the South Island, Curio Bay is one of the major attractions in the Catlins, attracting around 100,000 visitors per year. The town of Waikawa has an information center for tourists.

The now petrified logs, from ancient conifers closely related to modern kauri and Norfolk pine, were buried by ancient volcanic mud flows and gradually replaced by silica to produce the fossils now exposed by the sea.
