1. Khao Yai National Park, Thailand


To spot: Asian elephants, white-handed gibbons, Asian black bears
This UNESCO Natural World Heritage Site is a two to three-hour drive from Bangkok, but you feel like you’ve entered another world. There are over 2,000 square kilometres of lush forests perfect for peeping 300 species of birds, native deer, gibbons and the mighty Asian elephant. Home to various nocturnal animals like the Malayan porcupine and Indian civet, this is the spot for a thrilling night safari, which you can sign up for at the Khao Yai Visitor Center.
