O'Leno State Park Loop MAG1 sits along the Santa Fe River corridor, where limestone sinkholes and hardwood hammocks frame 1930s-era CCC stonework. Sites offer electric hookups, hot showers, and a dump station. Fees run $5 per night. Reserve ahead. The park fills on weekends.
The park offers a shady, full-facility campground with sites that accommodate tents and RVs, primitive hike-in campsites, primitive group campsites for organized groups, and cabins are listed among park amenities.
Historical Significance
One of Florida's first state parks, O'Leno was developed by the Civilian Conservation Corps in the 1930s. CCC crews built the suspension bridge, stone pavilions, and infrastructure that still anchor the park today. The site is listed on the National Register of Historic Places.Weather and SeasonsFall delivers the best camping window. Daytime highs settle between 65 and 85°F, nights drop into the 45–60°F range, and humidity eases compared to summer's steam. Mosquito pressure lightens, afternoon thunderstorms taper off, and the river holds steady for paddling. Migrating birds fill the hammocks and ravine forest. Crowds pick up on weekends but stay manageable compared to summer holiday rushes. Ticks remain active, so treat clothing and check yourself after hikes.
Natural Features and SceneryThe Santa Fe River vanishes underground here, swallowed by karst caves before resurfacing three miles downstream. The campground sits amid cypress swamps, hardwood hammocks, sandhills, and a steep ravine forest thick with live oak and magnolia. A hand-built suspension bridge spans the river near stone pavilions constructed by the Civilian Conservation Corps. Trails wind through sinkholes and follow the riverbank, where herons and egrets wade in shallow eddies. Birding peaks during migration, when warblers and thrushes move through the ravine canopy.
