Nyungwe rainforest is located in south-western Rwanda, at the border with Burundi and the Democratic Republic of the Congo. Nyungwe rainforest is probably the best preserved rainforest in the mountains throughout Central Africa. It is located in the watershed between the basin of the river Congo to the west and the basin of the river Nile to the east.
This forest is home to 25% of all of Africa's primates, including a large population of chimpanzees, which produce the national park's main attraction: chimpanzee trekking. Nyungwe Forest National Park was established in 2004 and covers an area just under 1000 sq km of rainforest, bamboo, grassland, swamps, and bogs. Along with its biodiversity, Nyungwe is an important water catchment for Rwanda and contains many natural resources integral to Rwanda’s human populations.
