Visit Islands in the Park

We have 12 diverse islands and peninsulas ready for exploring and 22 more that form an island wilderness. In all, there are 1,600 acres and 35 miles of undeveloped ocean shoreline on the islands. With so many places to choose from, it’s easy to visit an island that’s right for you—and what you like to do.

You can explore Boston Harbor Islands national park area by yourself, without any guidance, and have a great visit. But we also offer programs and tours for visitors with specific interests, as well as targeted groups of visitors, such as young adults.

Boston Harbor Islands provide critical nesting and feeding grounds for coastal birds. Visitors should avoid certain areas during the breeding season, generally March through July. Bird breeding sites include rocky bluffs and adjacent grass and scrub habitats, and the upper areas of beaches. Some nests are well hidden, so stay away from possible nesting areas to avoid disturbing them.
