About Thailand
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 — Chiang Mai, 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.
Thailand is cheap, direct, and endlessly flexible — it suits a week just as well as a month. The key timing consideration is the monsoon, which splits the two coasts: the Andaman side (Phuket, Krabi) gets wet from May to October; the Gulf side (Koh Samui) is drier in those months. November through April is the safest window for both coasts.
