There are a small number of locations where habituated chimpanzees may be viewed. Habituated groups are typically visited with small groups of tourists and your time with the chimps will be limited to approximately one hour per day. There are also a number of less touristed areas where the chimps are in the process of being habituated or are encountered but seen briefly and heard more often since they are not habituated.
There are currently three habituated areas that deliver the best chimp observation opportunities, Mahale National Park and Gombe Stream National Park in Tanzania, along with Kibale National Park in Uganda. These are places with sightings virtually every day and with habituated chimps that continue with their activities in the company of human observers.
Other Areas of Note
Uganda has a number of additional locations where it is possible to view chimps including Semliki and Kyambura Gorge. However, the levels of habituation and reliability of sightings are far below the listed Best Places. Likewise, in Rwanda they are in the process of habituating chimps in Nyungwe National Park which is an exciting development. On Rubondo Island in Tanzania efforts to habituate chimps is also ongoing. Chimp sightings at these locations are often fleeting and high in the trees.
In Kibale, Uganda it is possible to pay an extra fee to spend the entire day out on a chimpanzee research project, allowing for far more time with chimps than the customary one hour.
