One of Florida's first state parks, O'Leno State Park was first developed by the Civilian Conservation Corps in the 1930s. The park is located along the banks of the scenic Santa Fe River, a tributary of the Suwannee River, and features sinkholes, hardwood hammocks, river swamps and sandhills. As the river courses through the park, it disappears underground and reemerges over three miles away in River Rise Preserve State Park.

O’Leno State Park offers visitors the opportunity to unwind in a natural setting. Visitors can enjoy a day of hiking or biking on the park’s shaded trails. The Santa Fe River is a beautiful spot to launch a canoe or try your hand at fishing along its banks. Pavilions are located along the river’s edge, providing a serene backdrop for picnicking and relaxing. The shady, full-facility campground is the perfect place for a relaxing overnight stay. O’Leno State Park is located on U.S. 441, six miles north of High Springs.
