Khao Yai National Park

Buses depart from both Pak Chong and Bangkok for the national park. If traveling by car from Bangkok, turn off to the right shortly before Pak Chong on to Highway 2090 and follow the signs. Opened in 1962, the park covers an area of 2168 sq. km (837 sq. mi.) of land in the four provinces of Nakhon Nayok, Prachinburi, Saraburi and Nakhon Ratchasima. Hilly, forest scenery with mountains rising to a height of 1350 m (4429 ft) (still partially covered with original rain forest), picturesque waterfalls and idyllic lakes attract visitors to Thailand and Thais alike; because of this, the park should be avoided at weekends and on public holidays. The park offers comfortable accommodation - be sure to book well in advance through TAT in Bangkok.

The highest mountains, located in the southern section of the park, are Khao Laem (1328 m (4358 ft)) and Khao Khiau (Green Mountain, 1350 m (4429 ft)). Both can be climbed during a day tour, with the reward of marvelous views.
