Ko Lanta is a gorgeous island where you'll be certain to find an uncrowded beach. Located in the Krabi Province, one of the southern provinces of Thailand, Ko Lanta offers fantastic scuba diving with exotic marine life and grand coral reefs. The sunsets, too, are legendary—watch one over a glass of wine with someone you love.

The world's largest coral reef system, the Great Barrier Reef stretches almost 1500 miles into the Pacific from the tip of Queensland. Designated a Marine Park by the Australian government and a World Heritage Area by UNESCO, the reef is home to an extraordinary abundance of species and habitats. Snorkelling, diving and fishing are popular along the reef, nowhere more so than on the Whitsunday Islands, where the silica sands and aqua waters of the Coral Sea create the perfect beach escape.

Sun-drenched and built for fun, Australia's Gold Coast hugs Queensland's southeast coastline with beaches, shimmering high rises, and epic surf breaks. Though it's hedonistic at heart, there's also plenty of opportunities for adventure and family-friendly attractions beyond its well-known party scene.
