Cuc Phuong National ParkEstablished in 1962, Cuc Phuong is the oldest national park in Vietnam. Located only 120km southwest of Hanoi and nestled between the provinces of Ninh Binh, Hoa Binh and Thanh Hoa, Cuc Phuong boasts an engaging cultural and wildlife heritage and enchanting scenery. Magnificent Limestone Mountains rise up majestically from the green rice-terraces and traditional stilt houses of the Muong hill-tribe. Covered in a dense forest, this landscape forms the habitat for some of Asia's rarest animal and plant species. It is no wonder that researchers, naturalists, enthusiasts and conservationists alike are drawn to this corner of the world.The ancient forest harbours over 2000 species of trees, 110 species of reptiles and amphibians, and 125 mammals, including the Clouded Leopard, Delacour's Langur, Owston's Civet and Asian Black Bear. There are also an incredible 308 documented bird species. Visitors in April and May should be blessed with the chance to see literally thousands of vibrant butterflies.
