About McLennan Reservation

Venture into a rugged and remote tract of forested hills and wetlands at the edge of historic Tyringham Valley.

What makes McLennan Reservation a special place?
Round Mountain and its neighbor, Long Mountain, form the backdrop for the McLennan Reservation, nearly 600 acres of forested hills and wetlands at the southeastern end of Tyringham Valley. In the saddle between these 1,500-foot elevations lies Hale Pond, created when Camp Brook is periodically dammed by beavers.

From the entrance, a 1.5-mile trail follows the graceful rises and dips of this densely forested landscape before reaching the high plateau and Hale Swamp. The trail is moderate in difficulty, with some strenuous sections, but it pays off in striking views of unspoiled wilderness.

The reservation was once part of the Ashintully estate, whose gardens are located at the southern end of the valley and comprise another Trustees reservation: Ashintully Gardens.

1.5 miles of moderate hiking, strenuous in places.

When to Visit
Open year-round, daily, sunrise to sunset. Allow a minimum of 1.5 hours.

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.
