Park

Khao Yai National Park is one of Thailand's oldest and most visited parks and is part of the UNESCO World Heritage list. It contains one of the few and largest remaining monsoon forests in Southeast Asia. The park's main attraction is dense evergreen jungle that descends from high mountains into dramatic valleys with waterfalls and caves. Hundreds of wild species live here — elephants, macaques, gibbons, even bears and otters — about 300 resident and migratory birds, and many reptiles. If you're not an avid hiker, it's better to visit Khao Yai with a guide. The park is huge and some trails are quite long; there is even a three-day route that requires overnighting in the jungle.
