Assabet River Rail-Trail

Trail Map

Description Suggest an Edit

The Assabet River Rail-Trail provides a forested escape from the surrounding urban bustle. Traveling 5.6 miles (with plans to expand it) the trail connects the towns of Hudson and Marlborough and parallels the scenic Assabet River. As of autumn 2012, the trail is in three disconnected sections between Marlborough and Maynard. The trail crosses the Assabet River five times, the last crossing on a refurbished, historical wrought-iron railroad bridge. The 12-foot-wide corridor makes an excellent cycling route—just take care maneuvering between bollards located at the intersection of trails and roads; they are closer together than most.

The trail begins along State Route 62 in Hudson, marked by a restored 1921 blue caboose across the road from an ice-cream store. Look for the trailhead parking area. Passing through downtown Hudson, the trail weaves through the awkward three-way intersection of Villa do Porto Boulevard, Broad Street and the South Street extension.

Returning to the rail corridor, you'll cross a wooden bridge, followed by more trailhead parking on your right. The forested trail here provides a welcome buffer from the surrounding residential and urban landscape. At mile 2.4, you'll cross the Marlborough town line through a tunnel. The onward trail skirts a main road north, passing the Boston Scientific medical research and corporate center before reaching Fitchburg Street. Be careful at this intersection, since there are no bike lanes and the traffic light cycle doesn't allow much time to cross.

Beyond the crossing, there are no bike lanes. Look for the trail sign after the intersection, and you will find yourself leaving the traffic behind. As the path diverges from the road, the adjacent landscaped swathes on both sides of the route shield you from the busy urban environment. Side trails connect to the Assabet along this stretch.

Eventually, the trail will extend uninterrupted to South Acton along the Marlborough Branch Railroad corridor, which connected the Fitchburg and Massachusetts Central railroad lines. The five communities along the corridor are working together to develop the rail-trail.

Mostly a suburban ride

Nicely maintained trail with good parking at the Hudson trailhead. Not sure why it is called a river trail as any river is difficult to spot. Nice overlook of the reservoir halfway. read more

A beautiful way to enjoy an early Autumn afternoon

I can't believe I've lived in the 'boros for 16 years now and just got around to riding this trail. Given the weekend car traffic around here, it's a great way to enjoy the seasons and your bike without having to worry about getting splattered across more

A really nice ride.

A bit urban, like riding through people's backyards, but smooth and easy going. No bugs this time of year. read more
