The Santa Fe River goes underground in O'Leno State Park and reemerges over three miles away in River Rise State Park as a circular pool before resuming its journey to the Suwannee River. Surrounded by quiet woods and huge trees, anglers can spend a relaxing afternoon fishing on the river. Hiking and wildlife viewing are also favorite pastimes for park visitors.
Equestrians can explore over 35 miles of trails and end the day camping overnight with their horses. Located near the entrance to the park, the horse camp has primitive campsites, restrooms, and a 20-stall horse barn available on a first-come-first-served basis.
