About Rocky Narrows

By foot or canoe, enjoy incomparable views of the Charles River at its most serene as it slowly winds between granite walls. Or amble among pine groves and past wetlands along seven miles of trails and footpaths.

What makes Rocky Narrows a special place?
We think it’s the riverside location and great paddling as well as the reservation’s blend of mixed forest and wetlands that make for varied, and memorable, experiences. The reservation – The Trustees’ first – showcases the Charles River at its loveliest: a pastoral stream slowly moving between ancient cliff walls and steeply wooded hillsides.

Paddlers justifiably regard this stretch of the meandering, 80-mile Charles River as just about ideal. Canoeist or kayaker, river veteran or newcomer, you’ll revel in its gentle current and spectacular natural surroundings. A mixed forest of hardwoods and evergreens once again blanket a landscape cleared long ago for farming, and the 50-foot rock walls that form the Narrows themselves date back 650 million years.

For a change of scenery, emerge from your boat at the landing and head out on foot across miles of carriage roads and footpaths through rocky uplands and resurgent forest. A two-mile hike follows the river’s edge south before reaching successive overlooks. Rocky Narrows Overlook takes some effort to reach, but you’ll be rewarded with views of steep, hemlock covered cliffs that form a narrow river passage – the landmark that gives the reservation its name.

Further south along the trail is a granite bluff that bears the name King Philip, the Wampanoag chief who warred against the early settlers of the Massachusetts Bay Colony. From King Philip’s Overlook (in Sherborn Town Forest), visitors can view the marshes of Medfield and Millis, with Noon Hill on the distant horizon.

If the forests, wetlands, and riverbanks you explore here seem larger than 274 acres, that’s because they are: Rocky Narrows brackets the Sherborn Town Forest on three sides. This successful model of public/private land conservation has resulted in almost 400 suburban acres protected from development.

7 miles of trails, including those that pass through the adjacent 150-acre Sherborn Town Forest. Moderate hiking, strenuous in places. The property is a link in the Bay Circuit Trail.

Property History

Within 30 years of the Pilgrim landing at Plymouth, settlers had migrated inland along the Charles River Valley. By the 1650s, settlers were clearing land for farms, and the river played a central role in the growth of the community to be named Sherborn. Indeed, what we know as Rocky Narrows was called the “Gates of the Charles” in the Colonial era. Both the Wampanoag people and Puritan colonists considered the granite-walled river passage strategically important. This was particularly true during King Philip’s War (1675–76), when Native Americans fought back under the Wampanoag leader Metacomet, called “King Philip” by the Puritans. Visit King Philip’s Overlook off the Red Trail for a great river view – and a glimpse into Massachusetts’ early history.

In 1897, renowned landscape architect Frederick Law Olmsted, Jr., acting as acquisition agent for Augustus Hemenway, deeded to The Trustees of Reservations 21 acres on the river known as Rocky Narrows, the “Gates of the Charles.” It became The Trustees’ first reservation.

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 recommend that you download a trail map before you visit.
