The main tourist attractions in Uganda are wild animals, especially gorillas.

An excerpt from the article 32 facts about Uganda

The vast majority of mountain gorillas are found in Bwindi National Park, with a few others in Mgahinga National Park, both in southwestern Uganda.

The attraction of Queen Elizabeth National Park is tree-climbing lions. Lions only climb trees when chased by other lions or wild buffalos. Meanwhile, lions in QENP deliberately climb trees and rest on them in the afternoon when the sun is high in the sky - a unique phenomenon.
