21 days in Southeast Asia Itinerary

Offering a rich culinary heritage, sun-kissed beaches, exotic culture, tropical climate, and stunning landscapes, a Thailand vacation remains one of the world's greatest magnets for curious travelers. In between the busy and crowded cities, the Asian nation features a quiet countryside: a blend of lush rice paddies, flourishing tropical forests, and tiny villages living according to an age-old agricultural clock that continues to play a major role in the locals' lifestyle. A tour of Thailand reveals a deep devotion to Buddhism, exemplified by eye-catching temples lavishly decorated with golden Buddha statues, simple shrines, and lively religious festivals celebrated throughout the country.

While most Southeast Asian countries have at least one booming metropolis, none seem to bustle nearly throughout like Vietnam does. While busy locals zoom about on motorbikes, visitors fill their Vietnam vacations with a mix of cultural sightseeing and exploring the landscape. Big cities and towns boast colonial architecture, open-air markets, outstanding spa complexes, and modern restaurants. The country also features over 3,200 km (2,000 mi) of coastline dotted with sandy bays that attract scuba divers and kitesurfers. Away from busy urban centers, a tour of Vietnam reveals a rural landscape of lush rice paddies, jagged mountain peaks, and timeless villages unspoiled by the outside world.

For over six centuries, the mighty Khmer Empire flourished in Cambodia, a scenic land of majestic temples, pristine waterfalls, and dense jungles. A protectorate of France between 1863 and 1953, the country suffered under the Khmer Rouge, a ruling party remembered mostly for its part in organizing the bloody Cambodian genocide of the 1970s. Today, a trip to Cambodia will reveal the region's troubled history, but also some of Southeast Asia's most significant archaeological sites. Few tourist attractions in Cambodia match the splendor of Angkor Wat, a World Heritage-listed temple complex that represents the biggest religious monument on the planet.

An unusual blend of a developing nation and the modern world, Malaysia ranks as one of the richest countries in Southeast Asia, its prosperity largely resting on thriving high-tech industries. Malaysia vacations remain a more affordable alternative to the expensive tourism in some neighboring countries. Take a trip to Malaysia to explore busy cities filled with colonial-era architecture, tranquil tea plantations supporting a large portion of the local population, and dozens of scattered islands happily evading the worst aspects of mass tourism. While there may be fewer visitors, there's no shortage of fine beaches, mangrove estuaries, and verdant rainforests filled with exotic wildlife.
