Georges Island is dominated by historic Fort Warren, a Civil War-era fort known for its graceful granite archways and reputed ghost, the Lady in Black. The fort and its grassy parade ground are a popular place for a scenic low-stress walk. Take a ranger-guided tour or visit the new museum with exhibits about the history of the fort. Picnic under a shade tree. Get exceptional views of the surrounding islands and Boston Light from the ramparts and towers. Georges Island is a frequent stop for the island ferries and provides a jumping-off point for other islands.
