Length:                 South Bay Harbor Trail; 2.9 miles                            

Difficulty:             Easy. Flat, paved trail.


This is primarily a connector trail between the Southwest Corridor Greenway from Ruggles Street T-Station [Southwestern End] to the Boston Harborwalk at Fort Point Channel [Northeastern End].  Here it follows the same path as the Boston Harborwalk. You may access this trail from the Ruggles Station along the Boston subways Orange Line. For more information about taking your bike on the subway visit; MBTA-BIKE .

The South Bay Harbor Trail is a path that connects Boston neighborhoods Lower Roxbury, the South End, Chinatown, South Boston, and Fort Point Channel to each other and to the expanding amenities of Boston Harbor. The South Bay Harbor Trail provides an important link in the larger transportation network by connecting  the Southwest Corridor Greenway from Ruggles Street T-Station to Fort Point Channel and the Boston Harborwalk. The South Bay Harbor Trail includes the Melnea Cass Bike Path, which is sometimes referred to separately. It also shares the trail with the Boston Harborwalk; Fort Point Channel. For more information visit;  SOUTH BAY TRAIL .

Starting from the Ruggles Street T-Station/Columbus Ave/Melnea Cass Blvd [Southwestern End

Note; The Southwest Corridor Greenway travels North, along the East Side of the Ruggles Street T-Station, passing by a parking garage before coming to Columbus Ave & Melnea Cass Blvd

Cross Columbus Ave to the start of the wide, paved South Bay Harbor Trail. The trail then crosses Tremont St as it travels Southeast alongside Melnea Cass Blvd. The trail splits for bikes and pedestrians (sidewalk). Cross Shawmut Ave, Washington St, Harrison Ave and Albany St where the trail briefly reverts to sidewalk before crossing Hampden St. Places to eat along here. Turn Northeast and come to Mass Ave at 1 mile, where a cross-light takes you safely across. 

I'm not sure how they plan on connecting to the next section which travels underneath I-93. Currently, as of Oct 2023, there is a gap between the next trail section. You'll need to follow a 0.7 mile on-road detour.

Instead head left along Mass Ave (BIKE LANE) then right along Albany Ave (BIKE SHARROWS). Follow to Union Park St and Westside Frontage Rd at 1.7 miles. Here the paved South Bay Harbor Trail picks back up. The trail is well marked from here. The trail travels between Albany Ave and Westside Frontage Rd before turning right and traveling underneath I-93 and across Eastside Frontage Rd. Here the trail turns left alongside Eastside Frontage Rd and underneath I-93. Pass by the South Bay Harbor Buoy. Come to West 4th Street where you'll find a Map and informational Board.

Note; This is where the South Bay Harbor Trail; Bike Route emerges if you started from *Dorchester Ave [Northeastern End]. It traveled South, following a SEPARATED BIKE LANE along Dorchester Ave. Then West over the West 4th Street Bridge to here. 

Use the cross-light over West 4th St and continue North through Channel Park. Below is the Bass River across which are the RR Yards. This brings you to W Broadway & Trailer St at 2.1 miles. 

Note; If you cross the street and travel along a plaza below the highway it will take you down to Underground at Ink Block. Underground at Ink Block is the transformation of an 8-acre underpass located between Bostonís South End and South Boston neighborhoods into an active urban park. World-class street art, a Dog Park, paddle board court, bike storage facility, 24-hour security, commercial parking spots & more. The area also has walking paths, as well as benches and chairs to relax and take in views of the Bass River and RR Yard.  

After checking out Underground at Ink Block you'll need to head right across the New Broadway Bridge. A SEPARATED BIKE LANE takes you over the Bass River & RR Yards for South Station Transportation Center and brings you to *Dorchester Ave. Here the paved South Bay Harbor Trail turns right down to Foundry St and underneath New Broadway Bridge bringing you to Gillette headquarters. Straight ahead is another South Bay Harbor Buoy. Turn left on Dorchester Ave along a 2-WAY SEPARATED BIKE LANE and you'll come to the entrance for the US Postal Service facility at 2.4 miles. Here the South Bay Harbor Trail & Boston Harborwalk; Fort Point Channel meet.

Note; The trail continues right, but detour straight to Rolling Bridge Park, part of the Boston Harborwalk; Fort Point Channel. A short Loop Trail takes you around this small park and includes a pedestrian bridge over Cabot Cove. The park contains benches, interpretive signs and a big, red painted arm of the Old Colony Railroad Bridge that formerly occupied this site. At the time of its construction in 1898, the Old Colony Railroad Bridge was the largest rolling drawbridge of its kind. In addition, stones are arranged in a seating pattern to mimic a circular configuration of another bridge that occupied a nearby site. The trail then returns you back to Dorchester Ave.

The paved South Bay Harbor Trail & Boston Harborwalk; Fort Point Channel travel Northeast alongside Fort Point Channel on your left and Gillette headquarters on your right. Continue along the channel and you'll go around tiny Binford Park. Informational signage along the trail. Spot another South Bay Harbor Buoy. You pass by *Necco Street and come to the old Boston Wharf Company building after [*2.9 miles]. This building sits directly alongside the channel, but provides a corridor for pedestrians to pass through to Summer Street where I believe the South Bay Harbor Trail officially ends.

Note; If biking you may wish to bypass this and another section of the trail that contains stairs. Head right up * Necco Street to A St, then left on-road. Cross Summer St and continue along A St out to Congress St. Travel left down *Congress Street, past the BOSTON FIRE MUSEUM and return to the Fort Point Channel and South Bay Harbor Trail & Boston Harborwalk; Fort Point Channel at [*3.3 miles]

Follow the open corridor through the Boston Wharf Company to a set of stairs that bring you up to Summer Street. Cross Summer St to another set of stairs where the path continues along the channel. A ramp then brings you up to *Congress Street after [*3 miles]

Note; To connect to the Boston Harborwalk; Downtown travel left on * Congress Street (BIKE LANE) across the Channel. See; Boston Harborwalk; Downtown .

Crossing Congress St a boardwalk runs alongside the channel and past the Children's Museum of Boston and Children's Wharf Park where you'll find plenty of tables and food available. The trail then travels underneath the Seaport Blvd Bridge. Continue straight past the BARKING CRAB restaurant out to Old Northern Ave and the start of Fan Pier at 3.2 miles. The Harborwalk; South Boston continues straight along Fan Pier past the Moakley Courthouse as it travels along the Inner HarborSee; Boston Harborwalk; South Boston .
