Sankamphaeng Mountains

The Sankamphaeng Mountains rise between the eastern Thai plains and the Khorat Plateau. Their northern end joins the Dong Phaya Yen range, forming a forested escarpment above the lowlands. Rivers cut through the rugged slopes, and tropical forest covers much of the high ground. Together these mountain chains make a natural divide between the Chao Phraya and Bang Pakong basins to the west and south and the plateau country to the northeast.
