Rwenzori Theluji Festival in Kasese/Rwenzori
The Rwenzori Theluji Festival is listed as a Kasese event tied to the Rwenzori Mountains, a real UNESCO World Heritage mountain range home to Africa's third-highest peak and shrinking equatorial glaciers. Theluji is Swahili for snow, pointing to a festival built around the range's famous, now-retreating snow and ice cover. This research could not independently confirm a currently active festival under this name through a live website or press coverage.
The Rwenzori Mountains, straddling the Uganda-Democratic Republic of Congo border near Kasese, are a genuinely significant natural landmark: a UNESCO World Heritage Site whose Margherita Peak, on Mount Stanley, ranks as Africa's third-highest summit, and whose equatorial glaciers, remarkable for existing so close to the equator at all, have shrunk dramatically over the past century as the climate has warmed.
