Blue Spring State Park covers more than 2,600 acres, including the largest spring on the St. John's River. Blue Spring is a designated manatee refuge. During manatee season, which approximately runs from mid-November through March, several hundred manatee can be viewed atop the spring’s overlooks on cold days. The spring and spring run are closed to all water activity from mid-November to at least mid-March.
The spring´s crystal clear, 73-degree water can be enjoyed by swimmers, snorkelers, and certified scuba divers with a partner during our designated swimming season. Fishing, canoeing, and boating are also enjoyed along the St. John’s River. River boat tours are available; for reservations.
A self-guided tour inside the historic Thursby house, built at the height of the steamboat era in 1872, can also be experienced. In addition the park has plenty of picnic areas as well as three covered pavilions. Air-conditioned cabins and a full-facility campground are available for visitors interested in staying overnight.
