PHOTO: Carlo Sand Blow at Rainbow Beach, on the Sunshine Coast of Australia

In the U.S., we would call it a giant sand dune. In Australia it’s a sand blow. The Carlo Sand Blow, located at Rainbow Beach on the Sunshine Coast of Australia, is one of the country’s biggest. A short climb via steps up the rear of the dune leads to a viewing platform at the top, which offers sweeping views toward the Pacific Ocean, Double Island Point, and the village of Tin Can Bay. But you may want to make the trek to the top more than once, because the color of the sand changes as the sun moves across the skies. Sunrise and sunset are particularly beautiful, as the Carlo Sand Blow turns hues of gold and orange.
