Gaoyi Ridge, Mountain park in Suxian District, China.

Gaoyi Ridge is a mountain park in Suxian District, Hunan Province, shaped by red sandstone cliffs, natural streams, and dense forest cover. The terrain shifts between steep rocky sections and more open wooded areas connected by a network of paths and viewing platforms.

The red rock formations at Gaoyi Ridge were shaped over a very long period by the layering and gradual erosion of sandstone, a process typical of a broader geological belt found across southern China. This type of landscape, known as Danxia, was officially recognized as a natural heritage category in the early 21st century.

The name Gaoyi means "high chair", after the ridge's outline, which resembles a tall seat. The site is a national AAAA-level scenic area, and its red Danxia rock is the feature visitors come to see. Nearby sights include Dongjiang Lake, Feitian Mountain and Banliang ancient village.

Gaoyi Ridge lies on the border of Suxian District and Zixing, west of Hunan Provincial Road S215, the main road access. The scenic area covers 50.5 square kilometres of Danxia landform, so plan which section to walk before setting out. Nearby sites in the same area include Dongjiang Lake, Fenghuang Island, Feitian Mountain and Banliang Ancient Village.

Wild goats live on the steep cliff faces and can sometimes be spotted from the viewing platforms, moving across rock surfaces that most visitors would not attempt. Their dark coats stand out against the red sandstone, making them easy to notice once you know where to look.
