The Félou Falls are the main reason to make the journey to the Kayes region. Fifteen kilometres upstream from town, the Sénégal River drops 13 metres down a wide, irregular set of rocky steps over a width of nearly a kilometre. In the wet season (July–October) the falls are in full flow and genuinely impressive; in the dry season the water splits into multiple channels through the black rock formations, creating pools where it is possible to swim or wade. The spectacle is different at each season.
The falls are reachable by road from Kayes or by pirogue on the river. Local guides are available and recommended — the terrain is uneven and the falls cover a wide area. The surrounding landscape is scrubby Sahel savanna, hot and flat, but the falls themselves have a grandeur that is entirely unexpected. Come in the early morning before the heat becomes serious.
