So many sea turtles once hauled themselves out of the water to lay their 9 eggs in the sunbaked sand on Lanai’s northwestern shore that Hawaiians named the beach here Polihua, or “egg nest.” Although the endangered green sea turtles are making a comeback, they’re seldom seen here now. You’re more likely to spot an offshore whale (in season) or the perennial flotsam that washes up onto this deserted beach at the end of Polihua Road, a 4-mile jeep trail. This strand is ideal for beachcombing, fishing, or just being alone. It has no facilities except fishermen’s huts and driftwood shelters. Bring water and sunscreen. Beware of strong currents, which make the water unsafe for swimming.
