In Brazzaville, taxis are green. 700 CFA generally gets you around a neighborhood. This goes up to 1000 CFA at night. Drivers are generally fair with prices, and haggling is not required before getting in. Shared minibuses and taxis go just about everywhere else and prices are cheap but you have to be extremely patient, tolerant, and time rich, and they aren't particularly safe and comfortable, let alone roadworthy for getting to National parks.
