Across a narrow isthmus from Curio Bay is Porpoise Bay, closely guarded by these rocks at South Point which make the Bay itself relatively tranquil. This is a unique place: the only site where humans and dolphins (unfed, wild dolphins) live in close proximity.
The Hector's Dolphin, a small species which is critically endangered, has about 20 family groups here. We saw several dolphins swimming very close to people in the surf; there are lots of warnings about keeping away from the dolphins, but (like the penguins at Bushy Bay), no-one has told the dolphins themselves to stay away from humans.
