Uganda's Complete Safari
Everything in one route: Murchison's falls and rhinos, the wildlife of Mburo and Queen Elizabeth, then gorillas in Bwindi and chimps in Kibale to finish. The one trip that doesn't ask you to choose.
Based on two people sharing, low season, a camping-and-lodge mix. You get the line-by-line breakdown before you pay anything, and the figure in your first email is the figure you pay.
