Khao Yai, which translates to “Big Mountains”, is the name given to one of Thailand’s most tranquil national parks, known especially for its lush tropical rainforest, exotic meandering nature trails and majestic waterfalls. The park is also home to almost 2,500 plant species, 67 different kinds of mammal and over 300 species of bird. The abundant wildlife includes many endangered mammals such as elephants, gibbons, tigers, leopards and Malaysian sun bears. You are most likely to spot elephants during the winter months. Of course, going in winter has other benefits too, since this area enjoys considerably cooler weather year round than the bustling capital thanks largely to hilly elevation of 1351 metres. Obviously the coolest weather is to be had during Thailand’s winter period between November and February. Unlike the dreary winters in northern climates, Khao Yai’s winter heralds the blooming of a huge number of flowering trees, wild Orchids and other rare plants.
