Charles River Conservancy Volunteer

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 37,000 Conservancy Volunteers have contributed over $2.4 million of donated labor to improve the health, safety, and beauty of the Charles River parks. We are grateful to our 2021 Corporate & Foundation Supporters who have enabled this continued work.


Our open volunteer events welcome community members to join us in vital park maintenance work. Our community events are done for this season. Check back soon for our March 2023 dates!


We hope you will join us for a safe and fun way to get outside and give back to the parks that have given us so much!

Reserve Your Day:
Volunteer days typically take place on Wednesdays, Thursdays, and Fridays. View our available 2022 dates. You may also contact Sasha at to request additional dates and times that work best for your company or group.

To schedule a community service work day for your group or business, contact CRC Volunteer Program Manager Sasha Vallieres at Events book quickly, especially in the spring and fall, so please reach out at least one month before you would like to schedule an event.

Be Our Partner in Plastic Reduction:
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 2022 donation rates.
