Round Mountain and its neighbor Long Mountain form the backdrop for the McLennan Reservation, nearly 600 acres 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.

Ideas for Your Visit

From the entrance, a one-and-a-half-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.

Admission & Hours

Free to all. Open sunrise to sunset.
