End of Winter Neponset Greenway Bike Ride
Sunday, March 18, 2012

Celebrate the end of winter with a bike ride along Boston Harbor and the Neponset River Greenway from Castle Island to Paul's Bridge and back. We'll be especially interested in looking at where the next gaps will be filled along the Harbor in Dorchester and between the current trail loose ends in Milton and Mattapan. We'll be riding on moderate terrain with very little climbing for a distance of a bit over 25 miles. There will be extra traffic because the South Boston St. Patrick's Day Parade starts at noon.

This ride is sponsored by the the Boston Natural Areas Network. [Photos]

Getting There


The Boston Harborwalk passes through Castle Island. Or, take 8th St. from South Boston to Day Blvd. and follow either the road or the parallel path.


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 Andrew Station (Red Line):

  1. From Andrew Square, take Preble St. east.
  2. Where Preble St. ends at the rotary, use the rotary or crosswalks to reach the Columbia Road side and pick up the path.
  3. Cross Day Blvd. by the L Street Beach and join the path there


Take the JFK exit from Rte. 3 and follow Day Blvd. to the end. Please consider carpooling to the ride.

Bailout points

You can turn around at Pope John Paul II Park or Mattapan Square. Because you cannot take your bike on the "High-Speed" (Ashmont-Mattapan) trolley line, the closest T station to most of the ride is Ashmont on the Red Line, but it is a hike. In Mattapan and Hyde Park, we'll be near bus lines with bike racks which can get you to a T station or maybe home.
