6Whitehaven Beach, Whitsunday Island, Australia

Whitehaven Beach in Australia’s Whitsunday Islands is a seven-kilometer stretch of white silica sand that remains one of the most pristine beaches in the world. Accessible only by boat, seaplane, or helicopter, it offers seclusion and natural beauty. The beach’s Hill Inlet, where the tide shifts the sand and water to create a stunning mosaic, is particularly mesmerizing.
