Blue Spring State Park is in Orange City, FL. A rather small opening enlarges into a football-shaped area that may be 20x50 feet in size. Below 69 feet it becomes a smaller passageway to the bottom where the flow starts.
Another popular dive is Paradise Spring just south of Ocala. Paradise has a smaller opening that also enlarges. It has no outflow as it is a sinkhole.
