Khao Yai National Park - The 'Big Mountain'
Khao Yai, which means "Big Mountain", is the third largest natural park of Thailand. The highest peak rises 1,351 meters above sea level. Established in 1962, Khao Yai was the first to be declared a national park in the country. The 216,800-hectare Park is one of the most important watersheds for surrounding provinces. The Park covers portions of the provinces of Nakhon Ratchasima, Saraburi, Nakhon Nayok and Prachinburi. It is situated near the most westerly part of the Dongrak Mountain Range, with its highest region lying north and west of the Park. The lowest lying areas, ranging from 60 to 160 meters above sea level, are found along the valleys of the Khlong Wang Takhrai in the southwest and Lam Phraya Than and lower Sai Yai in the east.
