Big Lagoon State Park, State park near Pensacola, United States

Big Lagoon State Park covers 706.76 acres on Florida's northwestern coast, about 10 miles southwest of Pensacola. It takes in the northern edge of Big Lagoon as it winds toward Pensacola Bay, plus Wild Grande Lagoon and the alligator-inhabited Long Pond, a man-made freshwater pond. A wooden boardwalk on pilings crosses marsh and shallow water, curving toward a small parking area.

This location was long used by people living from the coast who gathered shellfish for food. Archaeological remains show the area had human inhabitants for hundreds of years.

The Florida Park Service manages this protected landscape as part of a network including neighboring Perdido Key and Tarkiln Bayou Preserve State Parks.

A 2.6-mile park drive is open to bicycling, and 4 miles of trails lead to footbridge overlooks at Long Pond and Grande Lagoon. The four-story observation tower gives views over the marsh and lagoon. There are 75 electrified campsites, a group camp, 17 picnic shelters, and a boat ramp on the Intracoastal Waterway.

The park's 1980s development partly disturbed a Woodland-period shell midden, evidence that people used this maritime habitat to gather shellfish long before it became a park. The site is one of several archaeological locations recorded within the park boundaries.
