Yenchao Geopark, distinguished for its mudstone and badland, is situated in Kaohsiung City. Major scenic spots include Wushanding mud volcano, Kuansuiping mud volcano and Shinyannui mud pond. In accordance with the Cultural Heritage Preservation Act, Wushanding mud volcano was designated as a Natural Reserve Area as of March 12th, 1992.

The Mudstone area is home to mud volcanoes and mud domes. Mud volcanoes are pseudovolcanoes where underground natural gas, liquid, and mud are pressured and erupt along earth fractures to form micro-landforms. Mudstones are made of silt- and clay-sized particles that are too small to see; they dry up to form small pictorial patterns and pile up to form cone-shaped “volcanoes”, both attractive to visitors. The co-existence of mudstone and mud volcanoes makes environmental education for school kid’s fun. With close proximity to the metropolitan area of Kaohsiung, Yenchao Geopark is famous for its bad land with good people and wonderful fruits.

Wushanding Mud Volcano is a typical conical mud volcano. There are several eruptive vents in the area. The largest eruptive vent here is currently the highest visible mud volcano in Taiwan. Wushanding Mud Volcano has its particularity in both geological and topographical studies. This particularity is not only scientific, but also educational and aesthetic.

Well-known attractions such as Foster-daughter Lake, Zhongliao Mountain and Chikuan Mountain around Yanchao Badland Geopark attract many cyclists. Those attractions become the must go places for cycling, which is the most environmental friendly new sport.
