Moeraki Boulders
The Moeraki Boulders are a collection of unusually large, spherical stones scattered along a scenic stretch of Koekohe Beach.
About this place
These geological curiosities are septarian concretions, formed from ancient seafloor mud around 60 million years ago and gradually exposed by coastal erosion. According to Māori legend, the boulders are the petrified eel baskets, gourds, and sweet potatoes that washed ashore from the wreck of the great voyaging canoe, Āraiteuru. The boulders vary in size, some reaching over two metres in diameter.
The best time to visit is at low tide, when the boulders are most exposed and accessible for photography and exploration. Some of the boulders are perfectly intact spheres, while others are cracked open, revealing a hollow, crystalline interior. Their unique appearance against the backdrop of the sea and sand makes this a popular and memorable stop along the coast.
