If you are a bird observer , forget Kibale NP, it is dead. A better bet is a guided walk at Bigodi Wetland which costs 20,000 shillings per person. It’s a bit steep in comparison with other costs but if you put the pressure on the guide, you can get about 4 hours guiding for your money which makes it reasonable. The bird life is very good and the young guides are quite knowledgeable. The park entrance fee is now US$20 (as are most parks in Uganda now) and the chimp walk is also US$20. Both are worth it because you have a 90 percent chance of seeing chimps of which I saw loads. The current East Africa LP does not say how travelers can book the bandas at the park. They can do so at the UWA office in Kampala. The people in the office are really friendly and helpful.
