Take a tour of Moeraki Boulders in New Zealand – part of the World’s Greatest Attractions series by GeoBeats. What's interesting about a bunch a rocks? A lot, if they're the Moeraki Boulders. These rocks are part of a strange and rare phenomenon of unusually spherical rocks. Located in New Zealand on a beach, these are large and almost perfectly circular boulders. Completely natural, boulders like these are only found in a handful of other places worldwide. The rocks tend to have hollow centers and a series of cracks radiating outwards. Visitors are welcome to look at, touch, climb on, and explore these unique stones.
