Bamako to Kayes through Kita
I drove the road through Kita a few days ago. From Bamako, the road to Kita is good asphalt. From Kita to Toukoto, the road is very good dirt, but it turns north at Toukoto. From Toukoto, the road (or roads) roughly follows the train tracks, crossing them occasionally. Some sections are actually the old railway bed, straight and flat, but most of the road is rough, with some thick mud after heavy rains, and many washed out sections. The path I took (and there may be others that I was unaware of) was rarely taken by automobile, and the trail sometimes was only single track. After Kale, there's a ferry that crosses the river to Bafoulabe, or just after Kale, you can jump to the south side of the train tracks, follow them to the river, and cross on the train bridge (probably not possible in a car). From Bafoulabe, the road doesn't improve much, as the Mich. map suggests. This is a beautiful route, especially from Toukoto to Bafoulabe; green and lush with impressive rock escarpments and old run-down French colonial outposts.
Enjoy your travels-
