Environmental Volunteering in Boston: Parks, Rivers, and Beaches

Boston's green spaces — from the Esplanade to the Boston Harbor Islands — are maintained almost entirely by volunteers. If you love being outside and want to feel the immediate impact of your work, environmental volunteering in Boston is the move. Most shifts are weekend mornings, fully outdoors, and welcome groups, which makes them ideal for a club, dorm floor, or just a few friends. Below are seven of the best environmental volunteer opportunities in Boston, with what you'll actually do and where to show up. Once you've picked one, drop your email on the Rally waitlist — this fall, you'll be able to coordinate a recurring park-cleanup shift with friends and watch your collective impact stack up.
