Large, classically beautiful half-moon-shape beach. The curving crescent of white sand sits at the base of picturesque mountains-some call it the most scenic beach in Hawaii. It's tough to argue the point. Hanalei, featuring a series of three beaches strung along a too-blue-to-be-true bay, offers a bit of everything. The western end features the calmest waters. The center of the bay boasts the highest surf, luring the island's top wave riders. You can walk the entire stretch; there are picnic areas, rest rooms, and showers along the way.
