Daisy State Park is a 276-acre Arkansas state park in Pike County, set in the foothills of the Ouachita Mountains near the Ouachita National Forest. Centered on the shore of Lake Greeson, a 7,000-acre fishing lake built by the United States Army Corps of Engineers in 1950, the park is defined by its reservoir setting and surrounding timberlands. Its significance lies chiefly in its role as a lakeside recreation area within the wooded mountain landscape of southwestern Arkansas.
