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.  

Bubbling mineral springs and pools promise maximum relaxation in Rotorua, on New Zealand's North Island. Therapeutic hot mud pools, dramatic geysers and a buried village are within easy reach of the city. What happens in the bubbling mud geysers of "Rotovegas"—the area at the top of Fenton Street—stays in Rotovegas. Once you've made the most of the mud, soar nearly 2,000 feet on the Skyline Gondola for views of Lake Rotorua, then zip back down to explore the lake by paddle steamer, fishing charter or WWII amphibious vehicle.

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.
