Chitwan National Park covers 932 sq. km. in the flat lowland region of southern Nepal which is listed in the World Heritage Site of UNESCO and regarded as one of the best managed park in Asia. You’ll have an excellent chance of spotting one-horned rhinos, deer, monkeys, and some of the more than 500 species of birds. If you’re really lucky, you may spot a leopard, wild elephant, or sloth bear – though it’s the once-in-a-lifetime chance to spot a majestic royal Bengal tiger that is the premier attraction. You’ll also have the chance to experience domesticated elephants, although how that interaction takes place is now undergoing a paradigm shift driven by animal rights concerns.
