Parking & Public Transporatation

Is it almost impossible to park your car within and around the CfA. There is some very limited free unrestricted parking along Huron Avenue (one block from the CfA), however we strongly suggest that you use public transportation to reach the CfA. If you absolutely need a parking space please let us know as soon as possible by contacting CXC Helpdesk.

Driving directions are available from the CfA website.

Train ("T") and bus Schedules and Maps can be found on the MBTA website. Subway fares are $2.00; bus fares are $1.50.

To get to the CfA by public transportation:

  • Walking:
    Take the Red Line to Harvard Square. Walk left toward the main part of the station as you exit the train. Go through the fare gates and up the stairs/escalators at the left to leave the station. Cross Massachusetts Avenue (the Harvard Coop will be directly in front of you) and walk to the right. Turn left onto Garden Street (there is a cemetary on the corner). After a few blocks, bear right at the light to stay on Garden Street. At the next light, the Observatory is on your left. The walk from the T station takes about 15 minutes.

  • By Bus:
    Take the Red Line to Harvard Square. Walk left toward the main part of the station as you exit the train. Go through the fare gates and bear right across the station to the ramps leading to the bus tunnel; take the upper ramp. Once through the doors, go to the berths to your left. Bus numbers 72, 74, 75, 78 (NOT 77) will take you to the Observatory. Ask the driver to let you off by St. Peters School; the Observatory is just up the stairs in the hill (on the same side of the street as the bus stop). Either climb those stairs, or walk one more block and enter the Observatory parking lot entrance on Madison Street.

    During rush hour you should have a wait of no longer then 10-15 minutes for one of these buses.


The closest hotel to the Observatory is the Sheraton Commander Hotel.

Information on other accommodations (hotels and many B&Bs) and restaurants in the Boston area can be found at the SAO Travel hotel list.
