The World's Best Beaches by Forbs and Onarchitects Although the Whitsunday Islands have some of the best diving and snorkeling in Australia, our vote goes to Bondi Beach because of the "sea-and-be-scene" atmosphere. Catalina Island, located off the coast of California, boasts 48 miles of coastline as well as a lost-in-time quality. Fijians are legendary for their friendliness as well as natural beauty, and Fiji features white-sand beaches, lagoons, palm trees and world-class scuba diving. When thinking of the Greek islands, most people think of the twin dens of debauchery, Mykonos and Santorini. For a different type of Greek beauty, try Corfu.
