Pack a picnic lunch. There's nowhere to eat once you're out of town and exploring the countryside.
It's best to book your own driver for this trip. You can do it as a day trip from either Banfora or Bobo-Dioulasso. Your driver should be able to arrange a guide for your hike in the Sindou Peaks.
It gets incredibly hot from February to April, so I would recommend avoiding this time of year, if possible.
You could drive rather than hire a local driver. However, this would require navigating police checkpoints on the highway and organizing the guide for the Sindou Peaks yourself prior to arrival.
