The capital and largest city of Congo with 9 million inhabitants is a large, sprawling city on the Congo River directly across from Brazzaville, Congo Republic. It is one of the craziets places on the planet right now.
When things return to normal there, be sure to visit St. Annes Cathedral (and the art market nearby), the botanical gardens, the Aviators and Stanley monuments and the ethnological museum at Lovanium University.
Also spend some time people watching and walking through both the old and new sections of town to look at the various shops. In the Gombe district, the most affluent part of town, upscale shops and restaurants can be found. At night, visit the restaurants and nightclubs in the Matonge area downtown, where the high pitched sounds of live pop music ring out. Be aware that the area is notorious for robberies. Plan to stay one night in the capital. Should you have additional time, hire a taxi or car with driver and take a day to drive along the Congo River road to Zongo Falls, stopping at the little villages along the way.
