Millions of years ago, much of New Zealand was submerged beneath a shallow sea. The temperate climate and accumulation of calcium-rich seashells turned sediment into limestone, which was thrust out of the ocean thanks to geological uplift.

Much of the exposed limestone has eroded and in unusual patterns, such as the Elephant Rocks which dot the countryside near Duntroon. These massive boulders are a sight to behold, and while they don't always resemble elephants in shape, they certainly do in size and somewhat in color.

Visitors won't have to worry about them stampeding either, as they're firmly planted in the ground, making these boulders ideal for climbers. Their spot on the Alps 2 Ocean Trail makes the Elephant Rocks popular for cyclists as well.
