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. Snorkeling, scuba diving and fishing are the most popular water sports here, though jet-skiing, wind sailing and squid fishing—yes, squid fishing—are also at your holiday-making fingertips. Check out the early-morning Duong Dong Market for an authentic local experience.

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.

Where else can you find an azalea-framed volcano to climb, a sisterhood of deep-divers, and ancient stone statues on which to make wishes? Jeju Island. A favourite with newlyweds (and K-drama fans), this popular retreat is also home to miles of golden beaches, winding coastal trails, and Jeju Waterworld, the area’s largest water park. No matter what your fancy, one thing is for certain: a day of sightseeing isn’t complete without enjoying some of the isle’s delicious raw seafood and famed barbecued black pork.

Bandung is Indonesia's third-largest city but lies close enough to Jakarta and offers cooler weather. Bandung features a large collection of Dutch Colonial architecture, as well as a beautiful botanic garden, zoo, golf courses and a wide variety of culinary offerings.

Yogyakarta boasts stunning architecture and a truly spiritual sensibility. The ancient Hindu temples of Prambanan look like hand-drizzled sand castles, while the Sultan's palace is reminiscent of a gilded music box filled with jewels. Known for its arts and handicrafts, Yogyakarta is a cultural hub, a nerve center for traditional and modern puppetry.

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.

The waterfalls, hot springs, and mountain views in Karuizawa make this Japanese town a popular destination for nature lovers. Hike an easy route to the tumbling waters of Shiraito Falls, then head to Kumobaike pond to relax in what legend says is the footprint of a giant. When you tire of the great outdoors, the Kyukaruizawa Ginza shopping district is a wonderful place to spend some time—and some yen.
