When we were in the Transkei me and Dad went to see a few waterfalls that fell into the sea. The hike was 10 km and there were only a few of us there. At one bit we stopped and had a swim in a natural pool and if you swam under a little of water then the water was frothing all around you so it felt like a jacuzzi. The walk was quite hard but very beautiful. When we got back we were all extremely tired!
