Cairns is the perfect city for merry revelers, passionate divers and adrenaline junkies, offering booming nightlife and heart-pounding adventure amid a vibrant, tropical setting.  This friendly Queensland city of 130,000 is a gateway to the Great Barrier Reef, Daintree National Park, Cape Tribulation, Cooktown and the rest of Cape York Peninsula. Embark on an eco-adventure or take a dip in a lagoon pool before hitting the town to unwind and shake what you’ve got Down Under.  

Nusa Dua is a hotbed of luxurious accommodations, golf resorts, fine dining and R&R. Surfing and diving are popular activities for more active visitors to this beach destination. Trek up the many steps to Mother Temple Besakih and combine sight-seeing with muscle toning. An array of spas, galleries and boutiques await those who prefer less exertion. Local Barong performances can be admired at Batubulan.

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.

Singapore is known as a bustling metropolis that also happens to be one of the cleanest and safest cities of its size in the world. (Just make sure you heed the local laws—something like spitting in the street might merely be considered rude in your hometown, but here, it carries a severe penalty.) You'll find historic sites like the Thian Hock Keng temple, superlative shopping (including gargantuan malls) and numerous beaches.

Bangkok is full of exquisitely decorated Buddhist temples—as you go from one to the next you’ll be continually blown away by the craftsmanship and elabourate details. But if you’d rather seek enlightenment in a gourmet meal, or dance the night away, you’ll also enjoy Bangkok—the restaurant and nightclub scenes here are among the best in the world.

Hong Kong's a great city for an adventurous eater. Stop at a street vendor for fish balls on a stick or stinky tofu. Bakeries offer wife cake, pineapple buns and egg tarts. Or opt for as much dim sum as you can eat. If you're tired of local and regional Chinese specialties, check out upscale offerings from some of the world's top chefs, like Joel Robouchon and Alain Ducasse.
