Some of the interesting features at Sleepy Hollow outside Port Elizabeth are a couple of old abandoned silver and lead mines that date back to the late 1700's. Although we did explore them on a previous visit, Chaos Boy wanted to go and have a look again. So off the two of us went one morning with torches in hand to explore the tunnels. The three tunnels go straight into the hillside with the longest one probably being about 60 meters or so in lenght.
