While traveling through the Ningxia semi-autonomous region in north-central China, I had the opportunity to check out a unique site. Shui Dong Gou (水洞沟) is one of the oldest Paleolithic excavations in all of China. It features ancient skulls and tools, as well as some models of old houses. But mostly, Shui Dong Gou has become a tourist haven, with nonstop fun for everyone. Sometimes it was hard to tell what was original and what was a recreation, but Shui Dong Gou still made for an interesting day away from the big city. Did I mention there were tractor rides?
