This nature reserve is one of the most important in Uganda, with a very high population of animals, including elephants and hippos, so it's easy to fine them. It is also quite easy to find lions, if you are lucky. I booked with Katunguru Safaris, located in a small town near Kasese, although I recommend booking with an agency that is easier, safer and better quality. But it will also be more expensive. I did not have much money and I hired a very nice guy I met in Katunguru. The downside is that, instead of having a four-by-four vehicle, sutable for the terrain, the guy had a Toyota Corolla, with a cracked windscreen and damaged battery (which I discovered while looking for a family of lions, when he stopped the car and we had to push it to start it), but he made up for with his charm, his knowledge and flexibility for my schedule.
