The rugged Sugar Loaf islets, a section of Back Beach on the west side of Paritutu and its waters 1km offshore, were made into a marine park in 1991. The islands, which are eroded volcanic remnants, are a refuge for sea birds and over 400 NZ fur seals. Most seals come here from June to October but some stay all year round. You can learn more about the marine park at the tiny Interpretation Centre on the Lee Breakwater promenade.
