The Pics de Sindou are a ridge of needle-shaped sandstone pinnacles running for about 50 kilometres west of Banfora, near the village of Sindou close to the Mali border. The pillars rise twenty to fifty metres above the bush in a thin cockscomb of pink and grey rock, eroded out of the same Proterozoic sandstone that crops up at the Dômes de Fabédougou.
The site has a walking trail along the foot of the cliffs that takes about three hours; a longer route climbs to the top of the ridge. Best done in the cool of the morning. The drive from Banfora is about 60 km on a partly tarred road, around 90 minutes — long enough that you should plan a full day for a visit. Local guides at the entrance can take you along the route most likely to spot the rock dassies and the colourful agama lizards that live in the cracks.
