Lanikai Beach, Hawaii

That Lanikai is considered the best swimming beach even by local Hawaiians should come as no surprise – after all, its name does mean “heavenly sea.” An offshore coral reef protects the deep turquoise lagoon, making the surf relatively mild and ideal for splashing around as well as kayaking, sailing, canoeing, and windsurfing. The mile-long beach itself, on Oahu’s windward side, is also quite scenic and has served as a backdrop in countless fashion shoots; imagine a wide swath dotted by tall swaying palms that cast shadows on the soft, sugary sand.
