Southeast Asia is a dynamic region of incredible cultural diversity, rich history, and fast-growing economies. Stretching across the eastern Himalayas to the Pacific Ocean, it is home to majestic temples, tropical islands, bustling cities, and unique cuisines that attract millions of travelers annually.
Comprising 11 independent nations, Southeast Asia lies between India and China and includes countries from both the mainland and maritime (island) zones.
