O Leno State Park is located in North Central Florida near High Springs. It has 2 loops of 30 and 31 camping sites respectively. The Magnolia Loop is closer to the Santa Fe River and other day use areas and trails. The Santa Fe River disappears into a nearby sink and reappears several miles away at Rising Rivers State Park. O Leno is one of the first Florida State Parks and was built by the CCC. The biggest concern camping here are the numerous ticks which seem to have great skill sets in finding you.
