Cabs are available around the clock. You can find them outside most hotels and at designated cabstands around the city, which are marked by signs. Taxis generally line up in Harvard Square, around South Station, near Faneuil Hall Marketplace, at Long Wharf, near Massachusetts General Hospital, and in the Theater District. You can also call or use smartphone apps, such as Hailo or Uber to get a taxi or other hired car.
A taxi ride within the city of Boston costs $2.60 at entry for the first 1/7 mile, and 40¢ for each 1/7 mile thereafter. Licensed cabs have meters and provide receipts. An illuminated rooftop sign indicates an available cab. If you're going to or from the airport or to the suburbs, ask about flat rates. (Be aware that you'll also need to pay a $5.25 toll and a $2.75 airport fee when leaving the airport, and a $2.75 airport fee when traveling to the airport in a cab.) Cabdrivers sometimes charge extra for multiple stops. One-way streets may make circuitous routes necessary and increase your cost.
Trying to hail a cab at around 2 am, when most bars close, can prove difficult, and there will often be a 20- to 30-minute wait if you phone for one. Heading to a cabstand may be your most efficient late-night choice. Avoid the sleek black town cars aggressively offering rides on the street or at airports (aka "rogue taxis") —their drivers sometimes charge more than the agreed-upon rate, and are sometimes even dangerous.
