The charming Vietnamese capital has aged well, preserving the Old Quarter, monuments and colonial architecture, while making room for modern developments alongside. Hanoi may have shrugged off several former names, including Thang Long, or "ascending dragon", but it hasn't forgotten its past, as sites such as Ho Chi Minh's Mausoleum and Hoa Lo Prison attest. Lakes, parks, shady boulevards and more than 600 temples and pagodas add to the appeal of this city, which is easily explored by taxi.

Breathe deep in Genting Highlands where, unlike nearby Kuala Lumpur, the air is fresh and clean. Aside from its resort life, visitors flock to hill station to enjoy cooler temperatures, mountain scenery, strawberry farms, and a relatively undisturbed, natural rain forest.

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.

A popular destination for golfers looking for better rates and more accessible courses, Bintan is also a nice way to escape the bustle of Singapore. A ferry ride takes between one and two hours, depending on where you’re headed. From there you can relax on one of the beaches or head inland for hiking and ATV rides or take a ride at the elephant park. There are a couple of towns on Bintan, but the island’s natural beauty is what draws visitors.

Go from the 13th century to the 21st in one day in Naha. Its ancient Ryukyu Kingdom centrepiece, Shuri Castle, has been restored and is the city's top tourist attraction. Meanwhile, on Kokusai-dori (International Boulevard), the pace never lets up as locals and tourists hop from restaurants to bars to nightclubs.

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.

On the south side of Jeju Island, Seogwipo offers swanky hotels, rugged cliffs, popular beaches and gorgeous waterfalls. The volcanic-rock cliffs located around Jungmun beach are a wonder. Make sure to visit the viewing platform to take in the spectacular vistas. A coastal city, Seogwipo's many activities revolve around the ocean, including diving and submarine tours. Many of the restaurants specialize in fresh, local seafood. There's also much to see and do inland, including temples, art museums, amusement parks and botanical gardens.

Home to nearly nine million and powering an economy that exceeds both Hong Kong's and Thailand's, Osaka packs quite a punch. The confident, stylish city is a shopping hub, with fabulous restaurants and nightlife. It's an ideal base for exploring the Kansai region: Kyoto's World Heritage Sites, Nara's temple and Koya-san's eerie graves are within 90 minutes by train. Top city attractions include the aquarium, Osaka Castle, Universal Studios Japan and the futuristic Floating Garden Observatory.

Regardless of season, it's hard not to succumb to romance as you wander Kyoto's atmospheric streets, gaze at the glimmering Kinkaku-ji Pavilion, enjoy the traditional dances of the geisha or feast at restaurants over the Kamo River. Only Rome has more World Heritage Sites than the former Japanese capital. But happily unlike Rome, Kyoto maintains its calmness and romance even among throngs of summer tourists. (Editor's note: Our list was compiled before Japan's devastating earthquake of March 11, 2011. Kyoto did not sustain major damage, but we encourage all travellers to Japan to monitor travel alerts from their government.)
