Kailua Beach was my favorite beach. Once a wide expanse of white sands, it’s become a victim of beach erosion. In fact, all of Oahu and Hawaii suffer from disappearing beaches. The beaches in front of the famed Outrigger and Royal Hawaiian hotels have to import sand from California, Australia, and other Hawaiian beaches to keep them alive. Locals complain about the coarseness and color of the imported sand. This hasn’t happened in Kailua and during high tide, the beach is all but gone, and the waves lap tragically at tree roots.
