On this seventh annual ride to Boston's Harbor Islands, we'll bike a total of 30 miles from Charlestown, starting along the waterfront, then through Everett,and Chelsea to East Boston, where we'll stop at the Blue Caboose at the south end of the East Boston Greenway sometime between 10:45 and 11:00 am. We'll check out the East Boston waterfront trail before following the Greenway and streets to Revere. We'll head east to Winthrop and follow the shore to the tip of Deer Island. We'll ride back through East Boston, stopping at Constitution Beach for lunch--there are lots of fast food places over the footbridge on Bennington St.--then cross Chelsea to the Mystic River and back to Charlestown.

You can also start the ride at 9:00 am in Adams Park in Roslindale Square for a 45+ mile ride. We'll start down the Washington St. bike lanes, the Southwest Corridor, Columbus Ave. bike lanes, and the Rose Kennedy Greenway to the Charles River start.

Getting There

From Boston's North End, the Boston Harborwalk which passes under the Charlestown bridge to the south end of the dam has been closed recently, so you should enter off Causeway St. east of North Station. You can also follow one leg of our route from Sullivan Square in Charlestown or the Gilmore Bridge from Cambridge 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.
