Great Brewster Island

The breathtaking views from Great Brewster Island are perfect for witnessing the magic of the harbor.

The largest of the Brewster Islands, this location offers spectacular views from the top of its 100 feet high bluffs, a spot where four lighthouses can be viewed. The island was named for Elder William Brewster, the first preacher and teacher for the Plymouth Colony. In recent history, it has served as home to summer cottages for local families and for U.S. soldiers who manned an observation post during WWII. Bunkers and remnants of military use still remain today.

Be sure to take in the amazing sights of Boston’s inner harbor, Massachusetts Bay, and Boston Light. Visitors can discover the mystery of tidal pools, go for a hike, or observe the gull breeding grounds and nurseries.
