Waikiki Beach is the shoreline fronting Waikiki and one of the best known beaches in the world. The beach has had its problems because of groynes build-out from the shore. This has led to beach replenishment projects in the past. In the 1920s and 1930s sand was obtained from Manhattan Beach, California, and transported via ship and barges to Waikiki. One disastrous sand replenishment project involved a man-made sand that the gentle surf turned into a concrete-like surface.
