Situated along St. John's River, there's quite a few treasures at Blue Spring State Park. Swimming, diving, snorkeling, and tubing are just a few of the water activities that can be done at Blue Spring State Park. What makes this state park so unique, though, is the ability to see some manatees in their natural habitat. Before the park was established in 1970, researchers found there was only a small number of the sea cows, less than 20. But after 2018 and careful protection efforts, there are now around 485 gentle sea creatures that call Blue Spring their home. Guests can also canoe or kayak, renting these at the park if they wish, or they can take a guided river boat cruise if walking 4.5 miles on Pine Island Trail seems a bit daunting. Bring a picnic and enjoy the day at Blue Spring State Park.
