Fort Desoto County Park
Fort De Soto Park is a park operated by Pinellas County on five offshore keys, or islands lying to the city's south-southwest: Madelaine Key, St. Jean Key, St. Christopher Key, Bonne Fortune Key and the main island, Mullet Key outside the city of St. Petersburg. The keys are connected by either bridge or causeway. The island group is accessible by toll road from the mainland. Historically, the islands were used for military fortifications, and remnants, as well as a museum, exhibit this history. Two piers, beaches, picnic area, hiking trails, bicycling trails, kayak trail, and a ferry to Egmont Key State Park are available. The park is a 'gateway site' for the Great Florida Birding Trail.
