While the rest of the world's continents fit into nice, tidy compartments, the nations that make up Southeast Asia -- Cambodia, Indonesia, Laos, Malaysia, Singapore, Thailand, and Vietnam -- often have more differences than similarities. Diverse geographical features, histories, religious and cultural heritages, economies, and politics across the region mean that the shortest journey offers cross-cultural comparison and new perspective.

Safety is a primary concern for travelers these days, and while it is important to stay updated on internal issues in any given country and to steer clear of any hot spots, the adventurous tourist paths through this vibrant region are ripe for exploration and replete with mystery, beauty, and ancient culture and wisdom.
