I highly recommend Lubumbashi. You can get there from Kinshasa by Congo Airways, which is about a two hour flight (though a bit pricey). It’s a new airline, and I can’t get over the Christmas music that plays every time you board and disembark from the airplane, kind of like the Brazzaville bridge lights that wish you a Merry Christmas and Happy New Year every evening. Oh, and that someone’s phone went off mid flight. How did that happen? I’m still not sure.
