Conservancy Volunteers

Each year, the Conservancy works with approximately 2,000 volunteers to perform vital park maintenance work and ensure permanent improvements in the parks. Volunteer events are a great way to get outside, learn more about the river, have fun working with friends, coworkers, and neighbors, and help restore the centerpiece of Greater Boston’s urban park system.

Since 2002, more than 28,000 Conservancy Volunteers have contributed over $1.9 million of donated labor to improve the health, safety, and beauty of the Charles River parks. View our 2019 volunteers and partners.


Projects run from either 9 a.m. – 12 p.m. or 1 – 4 p.m. (available on Thursday’s only) and take place from Cambridge to Watertown Square. Volunteer days are typically scheduled for Wednesdays, Thursdays, and Fridays. View our 2020 dates.

Location and projects vary based on maintenance needs, time of year, and size of group. Projects may include:

  • Invasive plant removal
  • Bench, fencing, and picnic table painting
  • Planting and maintaining garden beds
  • Fall bulb planting
  • Mulching
  • Raking leaves
  • Removing litter and debris

Events book up quickly, especially in the spring and fall months, so please contact us at least one month before you would like to schedule an event.

Planning an event in 2020? The Charles River Conservancy invites you to be our partner in single-use plastic reduction. Check out our Plastic Reduction Plan for ideas on how to reduce single-use plastic at your volunteer event. Help us achieve our goal!


Sponsoring an event pays for supplies, plants, staff time, and helps keep the parklands active, attractive, and accessible for all in the community. We ask our corporate and for-profit volunteer groups to support our Conservancy Volunteers program with a tax-deductible donation to the Charles River Conservancy. View 2020 donation rates.


Our 2019 season has come to a close! We’re looking forward to seeing you this Spring if 2020!
