Staggering beauty and heart-pumping thrills await in the resort town of Queenstown, which is also known for its Hobbits—much of the Lord of the Rings trilogy was filmed in the area. Outdoor enthusiasts flock to Queenstown for the kayaking, bungee jumping, jetboating, white-water rafting, hiking and skiing. More mild-mannered adventurers can take a quiet cruise through nearby Milford Sound, part of the Fjordland National Park World Heritage area, or sample South Island pinot noir from one of the region's 75 wineries.

In this nation of tiny islands and indigenous villages, Port Vila is the exception: a bustling port town with hotels, restaurants and markets to delight visitors and cruise ship passengers. The 150-foot-high Mele Cascades waterfall is the ideal place to refresh yourself in the South Pacific heat. For a glimpse of real Vanuatu culture and traditions, travelers say a trip to Ekasup Village is a must.

The gateway to the Great Barrier Reef, Airlie Beach is the main hub for all Reef activities and access to the Whitsunday Islands. Stunning views by day give way to a vibrant nightlife. The Airlie Beach Lagoon is a popular spot to relax and unwind. Visit nearby Conway National Park and Cedar Creek Falls to discover quiet coves, beaches and tropical rainforest.

Puerto Princesa’s claim to fame goes way beyond its swanky beach resorts and dolphin-watching cruises. The UNESCO-listed Underground River wows visitors with its low-hanging stalagmites and stalactites, and a cave that—due to its sheer size and rock formations resembling religious figures—is likened to a cathedral.
