Bandiagara is the gateway to the Bandiagara Escarpment, a 200-kilometre sandstone cliff that shelters the Dogon villages. The town itself is dusty and functional, but it is where most travellers arrange guides and supplies before heading out on multi-day treks along the escarpment.
Because the region is remote and transport is infrequent, few tourists make it here. Those who do find that the Dogon culture, with its elaborate mask ceremonies, hypnotic dances, and cliff-face architecture, has changed remarkably little over the centuries. Arrange your guide and provisions in town, then head for the escarpment. The Monday market is worth timing a visit around if you have flexibility.
Note that the security situation across Mali's Sahel region has been unstable since 2012. Check current travel advisories before planning a trip.
