The Bwindi Impenetrable National Park is the most biologically diverse rainforest in Uganda. 320 mountain gorillas — half the world’s population — live in its interior, and you can only see them in their natural habitat if you hike. Local guides will track the gorilla to their favourite hang-outs, and you can then sit quietly and watch them groom each other, feed, and play.

The Rwenzori Mountains (also called the Mountains of the Moon) offer numerous more challenging trekking routes. Popular routes include an ascent of Margherita Peak (5,109m), and the three-day Kyalavulu Loop through the rainforest. You might also want to consider walking to Murchison Falls, the dramatic outlet from Lake Victoria, or hiking through the evergreen rainforest of Kibale National Park.
