Boston Harbor Islands National and State Park

The largest recreational open space in Eastern Massachusetts, the Boston Harbor Islands are one of the northeast's great destinations. Comprised of 34 islands and mainland parks, the park attracts over 1/2 million visitors annually and is an important ecological habitat for wildlife.

Just minutes from downtown Boston and surrounding communities, the harbor islands offer magnificent views, remarkable history, and countless recreation opportunities. Whether you call Boston home, or are visiting for the first time, the Boston Harbor Islands should be on your bucket list.
