Jackson Blue Spring Traffic Light
One of the most distinctive features of Jackson Blue Spring.

Beneath the forests and springs of Florida flows a hidden network of underground rivers carved through limestone over thousands of years.

Florida contains one of the largest concentrations of submerged limestone caves in the world.These flooded cave systems formed as ancient marine limestone dissolved beneath the Florida aquifer, creating extensive underwater passages connected to modern springs and rivers.

The Hidden Rivers of Florida documents these cave systems through exploration, photography, and geological research. The site includes guides to major Florida cave systems, information about submerged spring caves, and explanations of how these underwater caves formed.

What Are Florida’s Hidden Rivers?

Many of Florida’s famous springs are the visible outlets of underground rivers flowing through vast limestone cave systems. These rivers travel through submerged passages before emerging at springs across the state. Cave divers exploring these systems have mapped miles of underwater tunnels that reveal how water moves beneath the landscape.
