Ferries depart 66 Long Wharf, Boston, MA 02110 · Boston, MA
A short ferry from Long Wharf turns downtown Boston into a national and state park of 34 islands and peninsulas. Georges Island centers on Fort Warren, a granite Civil War fortress you can explore corridor by corridor; Spectacle Island offers swimming beaches, a marina cafe, and drumlin-top trails with knockout skyline views. Rangers lead free tours, and both islands have picnic areas. Boston Harbor City Cruises runs the seasonal ferries, book ahead on summer weekends, and pack layers for the crossing.
