FAQs about flying to Boston
Getting around Boston
Boston has plenty of ways to get around, including the world’s oldest subway system, buses, trolley buses, ferries and commuter rail. The quickest, easiest and safest way to travel around Boston and Cambridge is the subway, the “T.” The subway will get you almost anywhere, and while the bus is cheaper, it can be much more confusing. Both the bus and subway run from early morning to late evening. A Night Owl bus service runs until 2:30am on Friday and Saturday nights. It’s easiest to get a travel pass for getting around, since different types of transportation require different tokens. Taxis are easy to find but can be costly. Don’t bother renting a car, unless you’re planning to go outside the city. Traffic can be a nightmare. Most rental agencies rent to drivers age 25 and up. Those drivers ages 21 to 24 will have to pay a surcharge.
Logan International Airport is served by an express bus service which, depending on traffic, takes between 30 and 45 minutes to get to the city. The ‘T’ also operates around the airport area as are local buses but for the most enjoyable way to reach your destination, take a water taxi or a water shuttle.
What is good to know if travelling to Boston?- The Boston Common (the Common) is the anchor for the Emerald Necklace, five parks spread over 404 hectares and 8 miles. The Necklace is the only remaining intact linear park designed by Frederick Law Olmsted, Sr. Next to the Common is the Public Garden, the country’s first public botanical garden. It’s also home to the bronze statues of Mrs. Mallard and her children from Make Way for Ducklings by Robert McCloskey.
- Bostonians are fervent and passionate sports fans. With the Red Sox, New England Patriots, Celtics, Bruins, and Revolution, there’s always a game somewhere. Some consider catching the Sox at a night game at Fenway Park to be a spiritual experience. If you plan to go to a game while you’re in town, it’s a good idea to get your tickets online before you arrive.
- A Boston CityPass will get you to the head of the line at several of the more popular attractions, and, if you’re planning on using the T, a Boston Visitor Pass may save you money too. Another option is the comprehensive Go Boston Card that includes attraction, transportation, dining, and shopping discounts. You can purchase the passes online or at several Boston locations.
- If you’re still in search of some good old Aussie cuisines, they’re not completely absent in Boston.
