Kibale National Park is widely considered the best place in Uganda to see chimps.
It has the highest success rate of any chimp trekking destination in the country. The chimps here have been used to visitors since the 1990s, so they are very relaxed around people.
This often allows you to enjoy long, close-up encounters watching them groom and interact. There are a couple of downsides: trekking in Kibale is relatively expensive, and it can get crowded when several tour groups are in the forest at the same time.
If you’re looking for cheaper options, Kyambura Gorge in Queen Elizabeth National Park is the most affordable. Nearby, Kalinzu Forest Reserve offers mid-priced treks with fewer visitors, run by the local community.
Budongo Forest, on the way to Murchison Falls National Park, is another quieter, off-the-beaten-track option. All three—Kyambura, Kalinzu, and Budongo—have a good chance of seeing chimps, though sightings aren’t quite as guaranteed as in Kibale National Park.
