The Casamance is Diola country, and the region's traditional villages — connected by sandy paths through forest and paddy field — are one of the most rewarding things to explore here. Unlike the Muslim-majority north of Senegal, the Diola have maintained a strong animist tradition alongside Christianity and Islam, and many rituals of the rice-farming cycle are still observed.
Village trails can be walked independently using locally purchased sketch maps, but a Diola guide makes the difference between passing through and actually understanding what you see. A good guide will explain the role of the baobab wine, show you the underground initiation chambers (from outside), and introduce you to village elders. Most guides are based in Ziguinchor or Cap Skirring and charge reasonable daily rates. Ask at your accommodation for recommendations.
