During the day, there are a bunch of local guys outside the campsite trying (sometimes over-vigourously) to sell you their wares. Take a look - some of them are really good! Particularly worth considering are the Malawi chairs - a pretty unique wooden design, and usually very well priced. Also, some cool paintings. I got my hair dredlocked while there (Stan the Man is the place to go). Make sure you bargain for everything, though!
But at night, everything is closed up, and they mooch out, playing bongo drums. These guys are really good. We stayed, and just chilled out with them for ages - nothing said, as nothing needed to be said. Very cool.
