The Arcadia Mill site is one of Florida's largest industrial complexes. The mill site is part of Historic Pensacola. The site is easy to find and apparently there is a museum and visitor center. We went on a holiday so all of that was closed, but we did not see anything marked as a museum or visitor center. The boardwalk is great for the kids and is marked with signs describing what the areas were used for. There is a picnic area so you can enjoy a lunch if you want. There is a small swinging bridge across a small river. Due to all the rain we have had, the water level was high. The bridge was practically under water and not really passable so keep a close eye on your kids so they don't get ahead of you.
