On a dramatic bluff overlooking Pensacola Bay, 19th-century Fort Barrancas was built by enslaved laborers atop an abandoned 18th-century Spanish fort. Now part of the National Park Service, the fort has endless dark passageways to explore but not much in the way of displays. A half-mile away via a walking trail lie the ruins of Advanced Redoubt, a Civil War–era fort. Call ahead to ask about scheduled tours.
