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.

The Whitsunday Islands are a collection of 74 tropical mini-paradises, floating in peaceful waters that double as a marine park and are a gateway to the Great Barrier Reef. Plan a romantic getaway or a fun family holiday that’s filled with sun, sailing, golfing, snorkeling and diving, all served up with a little slice of heaven.

Noosa is a world-famous surfing destination, known for its expansive beaches and colourful bays. Hike across Noosa National Park's cliffs and forests, canoe through the Noosa River Everglades, kayak across the open sea or just bask in the sunshine on golden sand that stretches and sparkles for miles. A day trip to nearby Fraser Island, a World Heritage Site where lush rainforests mingle with dry sand dunes, is a unique experience not to be missed.

The village cluster of Ubud is the ideal place to try a famed Balinese massage and soak up the ambiance of one of Asia’s top spa destinations. Acupressure, reflexology, stretching and aromatherapy star in the island's distinctively firm massage treatments. Ubud is also the vivacious centre of Bali’s arts scene, home to a small treasure trove of museums and galleries. Monkey around at nearby nature reserve Monkey Forest Park, home to hundreds of mischievous long-tailed macaques. Don’t miss the valley of tomb cloisters at Gunung Kawi.

Bali is a living postcard, an Indonesian paradise that feels like a fantasy. Soak up the sun on a stretch of fine white sand, or commune with the tropical creatures as you dive along coral ridges or the colorful wreck of a WWII war ship. On shore, the lush jungle shelters stone temples and mischievous monkeys. The “artistic capital” of Ubud is the perfect place to see a cultural dance performance, take a batik or silver-smithing workshop, or invigorate your mind and body in a yoga class.

Located on the southwestern side of the main island of Viti Levu, the Coral Coast has been a popular holiday destination for many years. It was one of the very first areas in Fiji to be developed for tourism. There's really nothing better than looking out at the ocean as the waves break on the reef. (On second thought, add a tropical drink to that picture.) Those looking to take in the natural beauty will find many opportunities for diving, fishing, golf and surfing.

Soak up the sun and some Vietnamese culture on Phu Quoc Island, where white sands and tropical waters entice beachgoers from all over the globe.

Check out the early-morning Duong Dong Market for an authentic local experience.

Forested hills, romantic white-sand beaches and crystal-clear waters greet visitors to tropical Palau Langkawi, the largest of the 99 islands in Langkawi archipelago.

Sample local cuisine at the night markets, hike to dramatic waterfalls or dive into an underwater marine park to take a guided glimpse at life beneath the sea.

You’re on a gorgeous island off the coast of Thailand—it doesn’t get much better than this. Spend the day on a lively, popular beach, or explore the Ang Thong National Marine Park’s secluded lagoons.
