Dive-site story
Blue Spring State Park centers around a first-magnitude freshwater spring flowing into the St. Johns River. Divers enter via the designated wooden dock and swim against the current toward the headspring. The basin transitions from a sandy slope into a dramatic limestone fissure, where deep water vents through a vertical fracture in the karst bedrock. Overhead cavern environments begin as you descend along the limestone walls, requiring strict buoyancy control and lights. The park is a critical winter sanctuary for hundreds of West Indian manatees; during the cooler months, all water activities, including diving and swimming, are closed to protect the resting population.
