01 Water that falls here ends up in Egypt
The chain is long and every link is documented. The Ruvyironza is the main tributary of the Ruvubu. The Ruvubu flows into the Kagera — the confluence sits on the Rwanda–Tanzania border, near the Rusumo Falls. The Kagera enters Lake Victoria. And out of Victoria comes the Nile.
02 Six thousand six hundred and seventy-one kilometres
The exact claim, and it is worth stating it exactly, is this: the headwaters of the Ruvyironza are the most remote source of the Nile when measured by river length from the mouth. The figure given is 6,671 kilometres. The point lies on Mount Kikizi, in Bururi Province, at 2,145 metres.
That precision matters because the "source of the Nile" has always had several candidates, and the answer depends on what is being measured. If the question is where the river called the Nile leaves from, the answer is Lake Victoria. If the question is which point of running water lies furthest from the sea along the channel, the answer is here.
Fifty-five kilometres in a straight line from Gitega. Less than many people cover on their daily commute.
03 A pyramid scratched with names
The site is marked by a masonry pyramid some three metres high, planted on an unfenced height, with a metal plaque on one of its faces. There is no ticket office, no visitor centre, no shop. There is a monument and a view of hills.
And there is one detail that says more than the plaque: nearly every stone in the pyramid has been scratched by hand with names and dates. It is not organised vandalism or graffiti; they are individual marks, made one by one across years by people who got there. It is the most honest visitors' book a monument can have.
04 What to do with this fact
First, a warning: the outing itself disappoints anyone expecting a spectacle. A spring captured behind stone walls with a metal spout, and a heap of stones in the shape of a pyramid. If you need the place to live up to the fact, do not go.
Second, the logistics. It lies some fifty-five kilometres south of Gitega in a straight line, plus whatever the plateau's curves add, and the last stretch is an earth track. That makes it a full-day outing, and one that only makes sense in June, July or August: with seventeen rain days a month, in November that track is not an option.
And third, which is what really justifies the article: you do not need to go. The fact works just as well from Gitega. It is enough to look at one of the hollows between two hills after a storm, with brown water running down loaded with red earth, and to know where it is going. That water has more than six thousand six hundred kilometres ahead of it before it reaches the sea.
