Anyone who has spent time in Boston knows that it is an expensive place to visit. Luckily, this New England hub has a number of great free attractions. History is at the forefront here, with many sights dating back to before the founding of the United States. The Freedom Trail is a well-marked walking path that passes places that played important parts in narrative of America's Revolutionary War. The “trail” is made up of easy-to-follow red bricks, and it stretches for more than two miles. Highlights include the sites of the Boston Massacre and the Boston Tea Party and famous buildings like Paul Revere's House and Faneuil Hall.
Other history-themed “trails” in Boston include the Black Heritage Trail, which passes through Beacon Hill, and the Irish Heritage Trail, which includes sites around Downtown. Free tours of the U.S. Custom House and the USS Constitution, an18th-century ship, are also great additions to a free itinerary. The Boston Saint Patrick's Day Parade is one of the nation's best and most colorful, while free concerts by the likes of the Boston Pops take place during Harborfest, held during the Fourth of July weekend.
