Blue Springs State Park

Blue Spring State Park covers more than 2,600 acres, including the largest spring on the St. Johns River. Blue Spring is a designated manatee refuge and the winter home to a growing population of West Indian Manatees. 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. Swimming or diving with manatees is not permitted; this rule is strictly enforced.

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. Johns River.

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.
