Guifeng, Nature reserve and mountain in Yiyang County, Jiangxi Province, China.

Guifeng is a nature reserve and mountain in Jiangxi Province featuring Danxia rock formations that span across extensive terrain and rise to about 545 meters in elevation. The site includes multiple developed viewing areas such as Yutai Bell Pavilion, Taoyuan Greenland, and Longtan Waterfall, offering visitors different routes and vantage points through the landscape.

Guifeng's rock layers belong to the Upper Cretaceous Guifeng Group, specifically the Hekou and Tangbian formations, deposited in the southern margin of the Xinjiang Basin at the junction of the Yangtze and Cathaysia plates. The site's 36 peaks and eight major viewpoints were praised by Ming dynasty traveller Xu Xiake as "rare under heaven on the river." It became a national scenic area in 2004, part of the China Danxia UNESCO World Heritage listing in 2010, and a 5A-rated scenic area in 2017.

The name Guifeng means "Turtle Peak" because the stacked rocks resemble a turtle. The Ming dynasty traveller Xu Xiake praised it as "the rarest turtle peak on the river". The cliff inscriptions (moya shike) at the site are listed as a Jiangxi provincial cultural relic.

Visitors should wear sturdy footwear since trails traverse natural terrain with varying elevation and ground conditions that can shift seasonally. The different viewing areas are spread across the site, so it's wise to plan adequate time and decide which zones match your interests and energy level.
