Thailand conjures images of white sand beaches and cerulean waters, peaceful temples, and lush mountain jungles. In Bangkok, a 21st-century playground, the scent of spicy street food fills the air, and the Grand Palace recalls the country's traditions. Outside the capital, the wonders of the countryside enchant, whether you are elephant trekking in the northern hills, exploring Ayutthaya’s splendid ruins, or diving in the waters of the idyllic southern coast. The unique spirit of the Thai people—this is the “land of smiles,” after all—adds warmth to any visit.
