The small area of Nepal holds a considerably high number of places recognized by UNESCO as “World Heritage Sites”. There are altogether ten World Heritage Sites in Nepal; seven of which are located within radius of 20 kilometers of Kathmandu. Swoyambhunath, Bouddhanath, Bhaktapur Durbar Square, Changunarayan, Pashupatinath, Kathmandu Durbar Square, Patan Durbar Square and Lumbini are labelled as Cultural World Heritage Sites; while Chitwan National Park and Sagarmatha National Park are labelled Natural World Heritage Sites.
Nepal’s first and most famous national park is situated in the Chitwan Doon or the lowlands of the Inner Terai. This ecologically diverse area is the last remaining home in Nepal for more than 300 of the endangered Asian one-horned rhinoceros and harbors one of the largest populations of the elusive and rare Bengal tiger. Besides rhino and tiger, Chitwan also supports a great variety of flora and fauna.
