About Cedariver

Explore this former riverside farm along the carriage road loop or enjoy a leisurely paddle on the Charles.

What makes Cedariver a special place?
Cedariver boasts beautiful frontage along the Charles River, and serves as a prime spot for paddlers to land their boats and take a hike. The mile-long cart path loop lets you explore the more than 50 acres of open fields, woodlands, and pristine riverbank. As red-tailed hawk soar above, watch for turkey and deer to appear amid the tall grass and goldenrod, Joe-Pye weed, and Black-eyed Susan.

Situated within a river environment serving both as a wildlife corridor and as part of Army Corps of Engineers’ flood-control efforts, this reservation achieves multiple conservation goals. Its 55 acres add to Millis’ substantial web of protected public land. And, through Cedariver and other nearby reservations, you can explore more than 500 acres of Trustees-protected land along this section of the Charles River.

Formerly a cart path, the 1-mile loop trail passes through open meadows and oak-pine forest, with access to the Charles River.

When to Visit
Year-round, daily, sunrise to sunset. Allow a minimum of 1 hour.

There is a canoe/kayak landing at Cedariver. Department of Conservation and Recreation (DCR) boat launch is across the street.

Property History

The Baker family operated a small farm here through the mid-20th century. Polly and Talbot Baker had moved to Millis in 1939 and were soon growing crops and raising livestock. In the 1970s, Polly Baker began her farsighted vision for protecting much of the landscape by placing a conservation restriction on it. Upon Mrs. Baker’s death in 2002 at the age of 94, the property, its two residences, and numerous outbuildings were generously donated to The Trustees.

Property Acquisition History
Cedariver was a gift in 2004 from the family of Polly Baker and her children Nicholas, Talbot, Hope, and Ben.

Conservation and Stewardship

Management Planning for Our Properties

Since 1891, The Trustees of Reservations have worked to protect special places in Massachusetts and maintain them to the highest standards. To ensure these standards are met, a program of careful planning and sound management is essential. Comprehensive property management plans are created for each reservation and are completely updated approximately every ten years. We often work with volunteers, property users, and members of the community to carry out this planning, which typically involves several steps:

  • Describing in detail the site’s natural, scenic, and historical resources; identifying management issues related to the protection of those resources. 

  • Describing how visitors use the property; outlining the opportunities that the property provides for people to become involved in the work of conservation and caring for their community.

  • Developing a detailed list of management recommendations, a work plan, and a description of financial needs for implementing the actions.

  • Developing a prescribed routine management program for the reservation that will guide staff work plans, volunteer involvement, and the allocation of human and financial resources.

Maps and Resources

Printed trail maps are distributed free from bulletin boards in parking areas. Please understand that supplies periodically run out. We suggest you download a trail map before your visit.
