Madison Blue Spring State Park
Lee, FL · Big Bend
Madison Blue rises in a round limestone bowl on the bank of the Withlacoochee River, about 82 feet across and holding a steady 72 degrees whether you show up in July or January. The water reads deep cobalt over the vent and shades to pale turquoise across the shelf, so a mask and snorkel turn up sunfish, catfish, and the dark mouth of a cave that technical divers have mapped for more than five miles underground. Float the short spring run to where the clear water meets the tea-colored river and you can watch the exact line where the two refuse to mix.
