O'Leno State Park is located on U.S. 441, six miles north of High Springs. Within the park, the Santa Fe disappears and flows underground for more than three miles before it again becomes a surface stream, spotlighting the geological distinction of the park. Including the adjacent preserve, the park encompasses in excess of 6,000 acres in Alachua and Columbia Counties. Other interesting features include sinkholes, hardwood hammock, river swamp and sandhill communities commonly found in north central Florida. In the mid-1800s, a town was founded upstream from where the river disappears.
