Known as Shilin or the Stone Forest, these are a set of karst formations that can be found in the Shilin Yi Autonomous County, which is around 90 kilometres to the east of Kunming. These tall rocks quite similarly to stalagmites, emanate right from the ground. Since they look like trees, they create the illusion of a forest which is why it is called the Stone Forest. Two parts of this area, the Suogeyi Village and the Naigu Stone Forest have been classified as UNESCO World Heritage Sites since 2007. These beautiful gigantic formations are considered to be over 270 million years old which have been caused by the dissolution of limestone. An interesting part of the culture here, one of its legends state that it is the birthplace of Ashima, a beautiful girl from the Yi people.
