Kibale Forest National Park
The park is famous for its chimpanzees, and many people come here for chimp tracking. Some of the best birding in central Africa is here too. The Kasese Crater Lakes are in the area.
Flora and fauna
The closest major town (that's well connected to Kampala) is Fort Portal. It's the last stop for an ATM and any major shopping/markets/restaurants.
From Fort Portal well paved road splits the park in two. There is no fee to pass on this road. But it's not a road where there are lots of places to pull off and explore.
The entry fee (Jan 2019) is $40. The fee is waived if you do the chimpanzee trekking ($150).
As of January 2019:
Entrance to the park - $40
Chimpanzee Tracking - $150 (entrance fee is waived)
Nature walk - $30 (plus entrance fee)
Night walk - $80 ($40 if added on to chimp tracking)

North of the Park are several volcanic crater lakes. Your hotel can arrange a guide to the "To of the World" for a 360 degree view. The walk will take you through tea plantations and farms. Costs around 50,000 per person, 3hrs.
The hotels warn that if you are caught without a guide, you can be fine up to $150. But that does not mean you have to visit the park with a tour group, only that you must coordinate you activities with a UWA office. They will issue you a guide as part of the activity fee.
Lots of lodges have space for tents. It is relatively safe as the only thing you really have to worry about are baboons, or hippos if you are on a lake. Good budget option.
A good option to stay is around one of the crater lakes just outside of the park (for a day you can get a boda to the entrance for app. 7-10 ths. UGX). All of the campsites also have lodging ranging from simple bandas, dorms or nicer cottages, and the proceeds go to finance community activities like primary schools and orphanages.
