Getting There

From Boston's North End, the Boston Harborwalk passes under the Charlestown bridge to the south end of the dam or you can enter off Causeway St. east of North Station. You can also follow one leg of our route from Sullivan Square in Charlestown if you are coming from north of the Charles River.

You can take your bike on T rapid transit lines and some bus lines for no extra charge. Details are on the MBTA website.

From North Station, turn (right from Orange Line, left from Commuter Rail) on Causeway St., then take the first left after North Station to the dam and cross it.

Parking in Charlestown is very challenging. Please consider biking or taking the T to the ride. You can pay to park at the Sullivan Square MBTA lot a mile from the start or a commercial garage close to the start on Constitution Road.

Bailout points

You can turn around in Winthrop before we head south to Deer Island or leave the group on the way back in East Boston or Chelsea, if you are headed north, or Sullivan Square, if you are headed west.

We'll go by several Blue Line stations in Revere and East Boston and will pass the Sullivan Square Orange Line station twice.
