Punakaiki's claim to fame is Dolomite Point, where a layering-weathering process called stylobedding has carved the limestone into what looks like piles of thick pancakes. Aim for high tide (tide timetables are posted in town; hope that it coincides with sunset) when the sea surges into caverns and booms menacingly through blowholes. See it on a wild day and be reminded that Mother Nature really is the boss. An easy 15-minute walk loops from the highway out to the rocks and blowholes.
