For more recent history, tour the Old Kromdraai Gold Mine, one of the country's oldest gold mines, where gold was found in 1881. Frankly, it's a little spooky. You don a miner's helmet and wander into the mine's murky depths on one-hour guided tours. It's not a difficult walk, and if you're lucky, you'll see bats roosting.
