Allow me brag by saying that, Uganda we have the source of the Nile and its found in Jinja. A visit to Jinja is very refreshing and relaxing. This is a place you can visit after the end of your safari shedule.
We can visit itanda falls, busowoke falls, source of the Nile, Activities are boat cruise, tubbing on the Nile, Rafting, Bangee jumping, Quard biking, city tour and many more. The views as you are driving to Jinja are very beautiful.
I personally recommend 2 days because this will make it more relaxed however 1 day can be organised. Also we can organise more days depending on what number of days you want to spend in Jinja.
This visit can only be arranged privately since its not on our solo women traveler calendar.
