1. Hanalei Bay | Kauai, HI
One of Hawaii's lesser-visited islands, Kauai is home to stunning beaches. Located on the island's north shore, Hanalei Bay is the largest bay in Kauai and offers more than two miles of soft white sand, a calm bay, and a mountainous backdrop. The beach is rarely crowded, which means families will have plenty of room to spread out, and in the summer, the bay offers excellent mooring for sailboats, stand up paddle boarding and swimming.
