What looks like a giant stone apple cleaved neatly in half by some otherworldly knife sits within the beautiful crystal clear waters of the Tasman Bay. This strange boulder makes for an unusual beach attraction.Known as Split Apple Rock, the naturally occurring rock formation is located just off the coast between Kaiteriteri and Marahau in Abel Tasman National Park. It’s made of granite and estimated to be around 120 million years old.According to Maori legend, the boulder was split by two feuding gods who were fighting to possess it. To resolve the issue, they used their huge godlike strength to break it in half. As such, the Maori name for the rock is Tokangawha, which means “burst open rock.” A more scientific theory is that water seeped into a crevice in the rock and then froze during an ice age, expanding and thus splitting the stone.
