Maquoketa Caves State Park is a state park of Iowa, United States, located in Jackson County. It stands northwest of the city of Maquoketa. In 1991 on the east side of the park were listed as a historic district on the National Register of Historic Places. Description The park contains more caves than any other state park in Iowa. A trail system links the caves, formations, and overlooks while providing a scenic hiking experience. Many areas on these trails have seen new construction, making the journey to the caves safer.
