Notes
Thailand's currency is the Thai Baht (THB, symbol ฿). Pay in baht; foreign currencies are not officially accepted. Indicative rate in 2026: 100 THB ≈ 3.0 USD ≈ 2.7 EUR (Nov 2026) - check a live converter before travel, the rate moves. Coins and small notes (20, 50, 100 THB) are useful because small vendors often cannot change a 1,000 THB note.
