My wife and I did a half-day on one morning with Abseil Zambia. It's great fun if you're fit and like adrenaline and adventure activities. In one morning we did the rappeling, the zip line (flying fox), and both solo (forward) & tandem (backward) gorge swings. The instructions were easy to understand and they were very safety conscious in operating the activities. Nevertheless, you'll still get quite an adrenaline rush when you step off the edge and start your freefall on the gorge swing. I bought the video ($50) and they delivered the DVD to my hotel the next morning, just as promised. The video is great! We particularly enjoyed our tandem gorge swing. You fall off the platform backwards together with your partner. Exciting and a little scary -- but it was the smoothest of all the swings we did. Have fun!
