Neponset River on the First Day of Spring
Saturday, March 20, 2010

Celebrate the arrival of spring 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 checking out the new bike path along the Truman Parkway in Milton and Hyde Park. We'll be riding on moderate terrain with very little climbing for a distance of a bit over 25 miles. Helmets are required, and it is a bit long for kids unless they're in a trailer or on a trail-a-bike or tandem with an adult.

This ride is cosponsored by MassBike's MetroBoston chapter and the the Boston Natural Areas Network.

You can turn around at Pope John Paul II Park or Mattapan Square. The closest T station to most of the ride is Ashmont on the Red Line, but it is a hike.
