05. Duke Kahanamoku Beach, Oahu, Hawaii

Kahanamoku Beach is located on the west end of Waikiki Beach, far from the large crowds elsewhere. It is the widest beach on this world-famous stretch of sand and protected by an offshore coral reef, making it a good beach for families with children. The nearby Duke Kahanamoku Lagoon is also a favorite bathing and swimming spot. This is one of the most picturesque beaches in the USA with the iconic Diamondhead volcano in the distance.
