Located just two hours northeast of Bangkok, the Khao Yai National Park is the oldest and largest national park of its kind in Thailand. Covering more than 2000 square meters in the Panom Dongrak mountain range, the park is sprawled across four provinces. The area features one of the largest monsoon forests in mainland Asia and has been listed as a UNESCO World Heritage site (as part of the Dong Phayayen-Khao Yai Forest Complex).
As you might expect then, the Khao Yai National Park is home to a diverse range of wildlife, and offers some truly spectacular natural scenery to marvel at. Some 200 elephants call the park home, as do tigers, leopards, Malaysian sun bears, deer, gibbons, snakes, and macaques. Keen birdwatchers will be in their element around the park’s designated walking trails, with the bird list here reaching over 390 species, including one of Thailand's largest populations of hornbills.
At only 175 kilometers from Bangkok, the Khao Yai National Park is easily reached from the capital by both train and bus. In addition, there are now domestic flights arriving into the area from other parts of the country. There is an entrance fee of 400 Baht for international visitors to enter the park.
