There's a great variety of things to see.
Uganda is not an obvious Safari destination. It's variety in scenery, people and wildlife makes it an truely recommended and unique travel, especially for someone who has already seen the big game Safari in Kenya or Tanzania. In Uganda you can see tree hanging lions in the morning and Mountain Gorillas in the afternoon, there is no other country in the world that has that. We went with drifters, a tour operator that uses very comfortable trucks (instead of jeeps) for groups up till 16 people. In my opinion, the trip was such a great experience because we camped almost every night and we had the most fantastic guide Anthony Washford to drive the truck, cook the food and plan all the excursions such as the astonishing Gorillas at Bwindi.
I have been to 4 other safari destinations and it is the most beautiful African country I have been to. Do not go if you wan to see the big five go to Kenya or Tanzania but if primates are your thing go to Uganda the people, the service is superb
