The Boston Natural Areas Network will host a free Sunday bicycle ride through some waterfront neighborhoods and into Boston Harbor, the network announced Wednesday.
The ride will begin in Charlestown, pass through East Boston, and continue — over land — to Deer Island, the network said in a statement.
“The route will follow scenic waterfront, city streets, greenway and off-road paths and end up at the tip of Deer Island, one of the most isolated yet connected parts of the city,” the network said. “The tour, while remaining on land, ends up in the middle of Boston Harbor with some spectacular views of the city and harbor.”
Hardy riders will begin in Charlestown at 10 a.m. on Sunday, July 28, and trace a roughly 30-mile path to journey’s end. Those interested in a less demanding 20-mile ride can join the cyclists about 45 minutes later at the caboose near the southern tip of the East Boston Greenway, at the corner of South Bremen and Marginal streets.
Riders are required to wear helmets and asked to register to participate. To register or for more information, call (617) 542-7696 or visit www.bostonnatural.org.
