Mount Danxia (丹霞山) is a famous scenic area near Shaoguan city in the northern part of Guangdong, China. The Danxia mountain is formed from a reddish sandstone which has been eroded over time into a series of mountains surrounded by curvaceous cliffs and many unusual rock formations (Danxia Landform). It is described in local signage as a "world famous UNESCO geopark of China". There are a number of temples located on the mountains and many scenic walks can be undertaken. There is also a river winding through the mountains on which boat trips can be taken to enjoy the scenery.
Particularly noted are two formations: a stone pillar called the Yangyuan ("male/father stone") that bears a remarkable resemblance to a phallus and the Yinyuan hole, which (especially to people who visited the Yangyuan pillar before) somewhat resembles labia.
