6. Barking Sand Beach, Kauai, Hawaii
Hawaii certainly has more than its fair share of weird beaches (another didn’t make this list). Right in the heart of the Polihale State Park, brings you to some ancient Hawaiian heiau’s, or temples, the forbidden island of Niihau, some burial sites and the famous Barking Sand Beach. The grains of sand on the beach have been documented by scientists, who have found them to be hollow. When you walk on them, or rub the grains together, it produces a sound that is exactly like the sound of a dog barking. Go figure.
