The best way to explore Boston is by foot, but you can also use Boston's subway system called "the T." A one-way subway ticket costs $2.40, and a day pass costs $12.75. Taxis and ride-sharing services are also available, but they can be more expensive. Expect to spend at least $15 for transportation during the trip.
If you have more time, add a visit to the USS Constitution Museum, Fenway Park, or Harvard Square. If you have less time, you can skip the Museum of Fine Arts and spend more time at the Freedom Trail or Faneuil Hall Marketplace.
Boston Logan International Airport (BOS) is the main airport in Boston, located 3 miles east of downtown Boston. The airport has four terminals and is served by many international and domestic airlines.
