Fodor's Expert Review Pigeon Key
There's much to like about this 5-acre island under the Old Seven Mile Bridge. You might even recognize it from a season finale of the TV show The Amazing Race. You can reach it via a ferry that departs from its new gift shop location, a trailer at Mile Marker 47.5. Once there, tour the island on your own or join a guided tour to explore the buildings that formed the early-20th-century work camp for the Overseas Railroad that linked the mainland to Key West in 1912. Later the island became a fish camp, a state park, and then government-administration headquarters. Exhibits in a small museum recall the history of the Keys, the railroad, and railroad baron Henry M. Flagler. The ferry ride with tour lasts two hours; visitors can self-tour and catch the ferry back in a half hour.
Bring your own snorkel gear and dive flag and you can snorkel right from the shore.
Pack a picnic lunch, too.
