The Gulf Island National Seashore is a huge National Park that spans much of Florida's and Mississippi's Gulf Coast. It includes Fort Massachusetts, Fort Pickens, the Advanced Redoubt and Fort Barrancas, amongst many other wonders. A single fee ($15 per individual at the time I'm writing this) gives one access to all of these forts for a week, and a little bit of planning (which I of course have never done in the history of me) would save one some cash. But we're at Fort Barrancas, so let's talk about Fort Barrancas!
