Madison Blue Springs State Park, Natural spring park in Madison County, United States.

Madison Blue Springs State Park centres on a spring pool about 82 feet (25 m) wide and 25 feet (7.6 m) deep, pale turquoise in the shallows and blue-green over submerged limestone ledges. A 150-foot spring run carries its water into the Withlacoochee River. Two wooden staircases descend the vegetated left bank, and a fallen tree trunk with exposed roots lies in the water beside a wooden platform on the right.

The park was established in 2002, when a private owner sold 38 acres at the spring to the state. Before that sale, local inhabitants used Madison Blue Spring as a fresh water source. Nestlé later bought two adjoining acres with an unused bottling permit, and its bottling plant opened in 2004.

The spring serves as a meeting place for people who want to swim, dive, and watch wildlife in their natural settings. It draws visitors from across the region who come to enjoy the water and outdoor activities.

The park is open daily from morning until sunset and offers good conditions for swimming and diving activities. Sturdy water shoes are recommended, and visitors should always check conditions before entering the water.

Below the surface lies an extensive underwater cave system that attracts experienced divers and researchers from around the world. The network of submerged passages creates a destination for those pursuing advanced diving exploration.
