Taxis are everywhere in Brazzaville and will sound their horn at the mere sight of a mzungu on foot. They don't have meters, so be sure to agree on a price before getting in. In general you can expect to pay CFA500 for a short hop, CFA1000 across town, and CFA2000 to the airport and northern bus stations. After dark you're going to have to pay about CFA1000 to CFA2000 to get anywhere. Crowded minibuses (CFA150) are nearly as common as taxis, though they're far less comfortable.
