Great Ocean Road (Victoria, Australia): The Great Ocean Road stretches 243 kilometers (151 miles) along the coast of Victoria, the southernmost state in mainland Australia. From the city of Torquay, southwest of Melbourne, to Allansford, you can drive the southern coast of Australia and take in the cliffsides and beaches that make this country and continent world-famous.

Koh Kradan (Trang, Thailand): This is one of the best beaches in Thailand, owing to the crystal-clear waters off its shores. It has that classic island mountain backdrop that has become so famous in many Thai resort towns.

Grand Anse (La Digue, Seychelles): This beach is one of the secluded beaches located in the island nation of the Seychelles, off the coast of East Africa in the Indian Ocean. On this secluded beach, the waters are crystal-clear, but the islands may soon be underwater due to rising sea levels, so act fast!
