Keawaula Beach (Yokohama Bay)
You'll be one of the few outsiders at this Waianae coast beach at the very end of the road. If it weren't for the little strip of paved road, it would feel like a deserted isle: no stores, no houses, just a huge, sloping stretch of beach and some of the darkest-blue water off the island. Locals come here to fish and swim in waters calm enough for children in summer. Early morning brings with it spinner dolphins by the dozens just offshore. Although Makua Beach to the south (off Farrington Hwy.) is the best spot to see these animals, it's not nearly as beautiful or sandy as Keawaula. Amenities: lifeguards; parking (no fee); showers; toilets. Best for: solitude; sunset; swimming.
