Nixs Mate, Little Brewster and Spectacle might sound like nifty microbrew handles, but those are just three of several islands dotting Bostons harbor.

These islands were a part of city life and commerce, but are now a section of the Boston Harbor Islands National Recreation Area, the largest recreational open space in eastern Massachusetts. Numbering 34 islands in all, 13 lie in Bostons Inner and Outer Harbor, and theres no better way to catch a sea breeze and cool down in the summer than heading out on the water.

Historic sites

Little Brewster houses the nations oldest light station. However, its not the oldest lighthouse because, thanks to the enthusiasm of the Boston militia fighting the British during the War of Independence, the original lighthouse Americas first, built in 1716 was destroyed. The current one was constructed in 1783.

Boston Lights first female lighthouse keeper Dr. Sally Snowman will tell you all about the buildings history on the guided tour. You can climb to the top, but the 76 steps and confined space isnt for everybody. The 3.5-hour round-trip tour toLittle Brewster Island via ferry is available for $41 with the climb, or for $30 without it.

Fort Warren on Georges Island was constructed between 1833 and 1860 to guard Boston Harbor. It also served as a prison during the Civil War, as well as World War II, due to fears over German U-boat attacks. Since 1947, the fort has been in civilian hands as a tourist attraction. Theres a visitor center and museum, plus a caf and gift store. Georges Island is on the regular, seasonal ferry service route from Long Wharf, available between May and October.
