Lying at the heart of southeast Asia, Thailand has five regions: the spectacular north, home to twelve hill tribes and rich in culture; the untamed mountainous northeast with Khmer ruins, elephants and cascades on the Mekong; the central lowland plains dominated by Bangkok and the old capital of Ayutthaya; and the idyllic islands and beaches of the south and east. Thailand is a feast for the five senses; its five-star luxury hotels, an unforgettable experience.
