Jinja is about a 2 hour drive northeast of Kampala without said traffic and lays on the northern edge of Lake Victoria. It is considered the source of the Nile River and was discovered by John Hanning Speke back in mid-1800. Like any good history story, this discovery was not without drama. Originally Speke set out on an expedition with Captain Richard Burton commissioned by the Royal Geographical Society to find the source of the Nile. Burton was convinced the source was Lake Tanganyika which contradicted Speke’s belief of Lake Victoria as the source.
Unfortunately Speke could not definitively prove his theory and shot himself by accident before the two men were set to debate publicly. It wasn’t until several years after his death that Speke’s theory of Lake Vic as the source of the Nile was proven by another expedition.

Aside from Jinja being the source of the Nile River and just a beautiful view, there are tons of tourist attractions including those for adrenaline junkies. Not only is there white water rafting and kayaking, but also ATV racing and bungee jumping. Our group decided to stick with a lazy horseback ride along the Nile; equally enjoyable but less likely to inflict bodily harm or risk of death.
The Ugandan countryside is really stunning with its verdant hills and thick tropical forests. The roads are peppered with plantations, usually banana and tea.
After just one weekend, I can see what all the hype is about. I will definitely be back to Jinja before I leave Uganda.
