Thailand has been one of Southeast Asia's most visited countries for decades, and it's earned that through sheer variety. Bangkok is a world-class food city with extraordinary temples and relentless energy. The north, around Chiang Mai and Chiang Rai, is cooler, quieter, and home to some of Asia's most beautiful temple complexes. Then there's the south: the Andaman Sea, the Gulf of Thailand, and hundreds of islands between them.
The food alone is worth the trip. Street pad thai, boat noodle soup, mango sticky rice, som tam. Thai cuisine at its source is a different thing entirely from what you get at home.
