Boston's transit gives visitors two gifts no other U.S. city matches: the Silver Line SL1, free from every Logan terminal to South Station, and a $2.40 flat subway fare on the system that invented American underground rail in 1897.
The T is compact enough to learn in a day: Red for Cambridge and Harvard, Green for the Back Bay and Fenway, Orange for the North End and North Station, Blue for the airport connection and the aquarium. Tap-to-ride takes any contactless card — no CharlieCard required — the subway is $2.40, buses $1.70, and the $11 one-day pass covers subway, bus, Silver Line and even inner-harbor ferries. Kids under 12 ride free.
The airport gift deserves repeating: the SL1 boards at every terminal curb, runs through the Seaport to South Station in 20–35 minutes, costs nothing from Logan, and the onward Red Line transfer to Harvard Square is free too. The Blue Line alternative — free shuttle to Airport station, then inbound — is the right answer for the North End, Government Center and North Station.
Boston's second transit network floats: MBTA ferries run year-round from the airport dock to Long Wharf, Hingham and Hull, with seasonal service to Winthrop and Quincy — the harbor commute that doubles as a sightseeing cruise. Water taxis ply the inner harbor on demand.
On land, the South Station Bus Terminal above the rail hall is New England's intercity hub — Greyhound, Peter Pan, FlixBus and the Concord Coach lines to New Hampshire and Maine — while Logan Express coaches (free from the airport to Back Bay, paid to the suburbs) carried a record 2.5 million riders in 2025. The honest tip: Boston's center is smaller than its reputation — Beacon Hill to Fenway is a thirty-minute walk, and the T is for the days it rains.
Our read: never pay to leave Logan — the SL1 is faster than any car at rush hour and free, and the Red Line connection puts Harvard Square 45 minutes from the jet bridge for zero dollars. In town, buy the $11 day pass only on days with three-plus rides; otherwise tap your card and let the $2.40 fares fall where they may. Ride the Green Line's outdoor stretch past the brownstones at golden hour — the oldest subway in America still earns its keep as a sightseeing tour.
