Naigu Stone Forest, also known as Heisongyan, is located 8 kilometers north of the main Stone Forest area. It is a model exhibition place of karst world heritage in the south.

According to Luliang Local Records in Kangxi era of Qing Dynasty, “40 li to the west of Shimen Peak is the place named Shimenshao”. This place was originally called Shimen.

Stones here mostly present shapes like castle, tower, and mushroom. For stone pillars, some look like blade and sword like those in Stone Forest while many others have sharp-top. They split from each other at the upper end but connect at the bottom, forming stone wall, city and array. Stone peaks hare are black, presenting a completely different style compared with those gray ones in Stone Forest Scenic Area. And this place is also broader, showing unique desolation, roughness and ancient pattern and giving people a sense of returning to nature. Baiyun Lake is at the entrance with tranquil surface like a mirror.
