You can see the Aviation Museum and Fort Barrancas. Next, past the Alabama State line, is Gulf Shores, Alabama. I recommend visiting the Weeks Bay Marine Reserve. Further west is Mobile, where I live now. Mobile is rich in history, and full of great places to visit, such as the USS Alabama, Fort Conde, and the Mobile Museum of Art.
Dauphin Island is also close to Mobile, and has all the charm of small island life.
All of these are wonderful. I prefer the Beau Rivage and the Treasure Bay casinos.
