The spring basin measures approximately 82 feet wide and 142 feet long.
It is classified as a magnitude-two spring, discharging between 10 and 100 cubic feet of water per second.
The water clarity is caused by the limestone karst topography that acts as a natural filter for the Floridan Aquifer.
The spring was once voted the 'No. 1 Swimming Hole in the United States' by USA Today readers.
The underwater cave system is part of a complex network that remains largely mapped by specialized cave divers.
The park is situated along the banks of the Withlacoochee River, which periodically influences the spring's water levels.
Madison Blue Spring State Park features a 25-foot deep natural limestone basin fed by a magnitude-two spring. The spring discharges crystal-clear water into the Withlacoochee River, maintaining a constant temperature of 72 degrees Fahrenheit year-round. It is designated as a protected aquatic environment popular for open-water swimming, cave diving, and snorkeling. The park occupies 39 acres of woodland surrounding the spring run. Facilities include designated picnic areas and a small swimming beach. Divers must hold appropriate cave diving certifications to explore the extensive underwater cavern system connected to the basin. The park is managed by the Florida Department of Environmental Protection within the Florida State Park system.
