From Wikipedia, the free encyclopedia.
Central Thailand is the region of Thailand, comprising a broad alluvial plain of the Chao Phraya River. It is separated from the North-East Thailand by the Phetchabun mountain range, and another mountain range separates it from Myanmar towards the west. In the north it gently changes into the more hilly north Thailand. The area was the heartland of the Ayutthaya kingdom, and still is the main area of Thailand.
