Some 14 percent of Thailand’s land area has been set aside for environmental protection. In total, there are now 79 national parks, 89 wildlife and non-hunting sanctuaries, and 35 forest reserves.

Kao Laem Ya
This marine national park is the nearest park from Bangkok. It is located at Ko Samet.

Doi Inthanon National Park
The park is located near the northern city of Chiang Mai. At 2,565 metres, the park is the kingdom's highest peak and its 482 sq km area forms one of the best mountain national parks in Thailand. Home to nearly 400 bird species and hailed as the Mecca of Thailand's bird watchers, the Inthanon mountain range is also a sanctuary for such threatened animals as the Asiatic black bear and the leaf monkey. Luxuriant flora such as orchids, lichens and mosses flourishes on its slopes.

Khao Yai National Park
Khao Yai is Thailand's oldest and most revered national park. Spanning four provinces, this 2,000-square-kilometer biological wonderland contains more than 70 mammal species, including tigers and elephants, as well as 320 varieties of birds. It has been declared an ASEAN National heritage site and probably it will be by the United Nations soon, too. Like most of Asia's wildlife sanctuaries, Khao Yai has been long under threat from poachers who are stripping the forest of its plant and animal wealth. In March 2000 the government launched the so-called Khao Yai Conservation Project, so hopefully future generations are able to visit this outstanding piece of nature. The park has over 50 km hiking trails, many of them formed by wildlife movement. Elevations range from 100 to 1400 metres. It is easy to get lost so it's recommended to hire a guide. Trips to the park can be arranged easily from Bangkok.
