Often lauded as one of the most beautiful beaches in the world, Lanikai is most worthy of a day trip. Step through a quiet residential neighborhood to find yourself on powdered sugar sands, gazing at calm turquoise waters and the twin islands of Nā Mokulua in the mid-distance. The sight is guaranteed to take your breath away. While always more serene than buzzing Hawaii, Lanikai can get crowded during the peak season. It’s best to head there on weekdays if you can.
