Located on the banks of the scenic and unique Santa Fe River, a tributary of the Suwannee River. Within O'Leno, the Santa Fe disappears and flows underground for more than three miles before it again becomes a surface stream at the River Rise. Fishing is allowed along the banks of the river (except in the swimming area) and in any of the many sinkhole ponds throughout the park. You may also launch a canoe (when the river is high enough) and fish upstream from the picnic area. Fish commonly caught are bass, brim and catfish.
