The Khao Yai National Park (Thailand’s second largest and a World Heritage Site) is famous for its dense virgin forests, streams, waterfalls and high-altitude plains. This is great city escape for those looking to get back to nature during their stay in Bangkok. About 175 km Northeast from Bangkok lies Khao Yai - a big mountain region in Thailand that covers an area of about 2.200 qkm and is one of the country’s largest national parks. Within this refreshing and scenic landscape, with its bizarre mountains, there is still untouched jungle, mountain streams and many waterfalls, with a preserved animal world, which includes wild elephants, buffaloes, deer’s porcupines, varieties of monkeys, parrots and parakeets, huge hornbills and another 250 species of birds. There are even tigers, clouded leopards and bears living here. A unique experience awaits you at dusk, when you see more than one million bats fly out and leave their daytime home in the caves.
