Metropolitan Manila encompasses six cities and 12 towns. Located on Manila Bay in the South China Sea, and bisected by the Pasig River, the capital of the Philippines is historic and modern, rich and poor. A popular sight is the walled area called Intramuros. The capital during Spanish colonization, Intramuros has retained old dungeons and gunpowder rooms but added art galleries and theaters. The city is filled with museums, shops, parks and churches, plus enough nightlife to last until dawn.

Tagaytay secures its place on most Philippines itineraries with its location above Taal Volcano's active crater. Views of the crater lake and a refreshingly cool climate make the town an enticing destination—not to mention the famously unfinished People's Park in the Sky.

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.

Vientiane is the capital and largest city in Laos. Located on the banks of the Mekong River, Vientiane is a city steeped in legend and history. The city is the home of the massive gilded stupa, Pha That Luang, a national symbol of Laos. The streets are lined with trees, French colonial buildings, street markets, Buddhist temples, and noodle shops. Just outside the city is Buddha Park, a garden littered with over 200 cement sculptures depicting the gods and monsters of Buddhist and Hindu myth.

Busan is Korea's second largest city.  Tourists often come to this region to hike and to visit the Buddhist Temples located deep within the region's mountains. The Beomeosa Temple, founded in 678 AD, is perhaps one of the most frequented temples in the area and is always packed with worshipers and tourists. For art buffs, Busan offers several museums and historical buildings. If scenery is your thing, try visiting the Dongbaek Island, or bird watch at the Nakdong river estuary.   

Kodaikanal has an endangered animal called the grizzled giant squirrel. To us, that alone is reason to book a trip ("grizzled giant squirrel" might be the best animal name ever). Perched on the woodsy southern crest of the Palani Hills, nearly 7,000 feet above sea level, this popular lakeside resort town is a magnet for nature lovers. Wander the peaceful slopes, keeping an eye out for birds, exotic flowers and, of course, grizzled giant squirrels.
