Yesanpo National Park, National park and geological formation in Laishui County, Hebei Province, China.

Yesanpo National Park is a protected area in Hebei Province made up of several sections organized around deep gorges and river valleys. The most visited section is Bailixia Gorge, where steep rock walls rise on both sides of a river that cuts through layered stone.

Yesanpo lies where the Taihang and Yan mountain ranges meet, and its gorges and karst rock formations are cut into that junction. In 2006 the park was named part of the Fangshan World Geopark together with Shidu and Baishi Mountain, and it holds China's AAAAA rating. In late July and early August 2023, torrential rain from the Beijing-Tianjin-Hebei storms badly damaged the scenic area.

The name Yesanpo means "Wild Three Slope", referring to the three steep slopes of the site. The park lies where the Taihang and Yan mountains meet, and its seven scenic areas are named for their landforms and features, such as Bailixia (Hundred Li Gorge), Baicaopan Forest and the Juma River. Visitors travel to Yesanpo or Bailixia stations on the Yesanpo Tourist Special Line from Beijing West Railway Station.

The park is west of Beijing and can be reached by train without needing a car, which makes it one of the more accessible parks in the region. Footwear with grip is worth bringing, as paths through the gorge sections run over uneven and sometimes wet ground.

At certain points inside Bailixia Gorge, the walls narrow so much that a person can touch both sides at once. This makes the walk through the gorge feel very physical, almost like moving through a crack in the earth rather than a trail.
