Poʻipū Beach Park is the most popular beach on Kauaʻi's sunny south shore, and for good reason: it faces south rather than north, which means it is sheltered from the winter swells that make the north shore beaches dangerous for swimming. The beach is divided by a natural sandbar into two separate areas — the calmer, shallower section on the west is ideal for families and snorkeling, while the more exposed east side has better wave action. It has been named one of America's best beaches on multiple occasions.
The rocky outcrops at the east end of the park are good for snorkeling, with turtles, reef fish, and the occasional monk seal in residence. Hawaiian monk seals — among the most endangered marine mammals in the world — haul out regularly on the beach to rest. When they do, rangers cordon off the area and ask visitors to keep their distance. Seeing one up close, from a respectful distance, is a genuine thrill.
Poʻipū is the hub of the south shore resort area, with hotels, restaurants, and activity centres a short walk from the beach. Sunset at Poʻipū is reliably spectacular — the south-facing orientation and clear sky make for the kind of colours that justify the reputation.
