In the afternoon of our one day in Kunming, our host arranged for us to visit the Stone Forest (Shilin), an impressive set of limestone formations believed to be over 270 million years old. It is certainly worthy of its UNESCO World Heritage Site status. The Stone Forest is similar to the limestone karst islands we saw during our visit to Halong Bay, Vietnam except these look much taller. This is because the site that the Stone Forest sits on was once a shallow sea. I imagine if Halong Bay was drained, it would very much look like the Stone Forest. The Shilin National Scenic Area, which is located about 1.5 hours drive from Kunming, is quite large and divided into seven areas. Although there were numerous tourists there (mostly domestic tourists), we were able to walk through areas that had very little and at times no other tourists.
