Boston Harbor has a surprising number of islands - most people don't realize the islands are even there, let alone 34 of them! Many are part of a combined National and State Park and accessible by ferry from Long Wharf. The islands offer hiking trails, beaches, ranger tours, camping, boat cruises, nature walks, historic sites and various events throughout the warmer months. There are even a few winter tours.
Georges Island is the second most accessible island - the site of a historic fort with a newly renovated visitor center which is very accessible. You can get into the fort area and parade grounds by wheelchair. Selected interior areas can be accessed via ramps. Since the fort is built into the landscape with multiple levels, a good portion of it resists full access but is still fun to view.
If you live in the Boston area or are planning a trip to Beantown, consider an excursion to the Boston Harbor Islands!
