Boston Harbor Islands – In Detail

The Boston Harbor Islands National and State Park is a unique archipelago comprising 34 islands and peninsulas scattered across Boston Harbor, offering a blend of natural beauty, historical significance, and recreational opportunities. Situated just offshore from downtown Boston, these islands provide residents and visitors with accessible escapes into nature, rich cultural heritage sites, and a variety of outdoor activities within a short ferry ride from the city.

The Boston Harbor Islands span an area of approximately 1,000 acres of land and more than 2,000 acres of surrounding marine environment. The islands vary greatly in size, landscape, and usage, ranging from small rocky outcrops to larger, forested islands with beaches and historic forts.

Access to the islands is primarily via seasonal ferry service departing from several points in Boston and nearby towns, especially from the Long Wharf and World Trade Center piers. Some islands are also accessible by private boat or kayak.
