      Meadow Loop

      This trail descends into a field where hikers can choose which direction to take on the loop trail. Heading counter-clockwise the trail winds along the woodland edge and through the forest. It continues around a knoll that is an old apple orchard. On the western side of the knoll, the path crosses between two large sugar maples and two large boulders before emerging back into the meadow. Along the way, take the opportunity to rest on one of the benches, and enjoy the expansive view of the wetland habitat.

      The Meadow Loop was designed and constructed by Peter S. Jensen & Associates, LLC.

      Woodland Trail & Whale Rock Trail

      Located off the east side of the accessible trail and winds through the upland forest. At 0.6 miles the route transitions to the Whale Rock Trail, which gradually climbs to a unique rock feature, known locally as Whale Rock. Whale Rock is home to sensitive and unique habitats. Please protect this important area by staying on the trail at its endpoint.

      The Woodland Trail and Whale Rock Trail were designed and constructed by BNRC staff with construction support from BNRC volunteers, Greenagers, and the Student Conservation Association.

      The 267 acres of the Thomas & Palmer Brook reserve slope upward from the brook through old pasture, a wetland and mature forest to a dramatic high point of exposed bedrock. An accessible trail through the meadow leads into the forest, winding past boulders and large sugar maple trees. The wide Woodland Trail climbs through the forest, leading to a narrow hiking trail ending at Whale Rock.

      The Thomas & Palmer Brook reserve, established in 2015, is on the south-western slope of the Threemile Hill ridge that is a backdrop to much of Great Barrington’s commercial activity. Much of the land comprising the reserve was farmed well into the last century. The property is part of a habitat corridor reaching from Monument Mountain Reservation, Housatonic Flats, and Fountain Pond State Park in the west to the Butternut Ski Area and Beartown State Forest in the east. Keeping the entire contiguous corridor protected is important for wildlife and climate resiliency.

      BNRC envisions the site as an anchor for future conservation along the Threemile Hill ridge, and for connected hiking routes as part of The High Road, an effort underway to connect trails and conservation to towns throughout the Berkshires.

      The old pasture is now dense with pollinator-loving goldenrod and milkweed. The forest consists of mixed hardwoods, white pine and hemlock. Beaver activity is visible near the brook and wetland. Birds that have been attracted by the property’s diverse habitats include the American woodcock, the blue-winged warbler, the chestnut-sided warbler, the eastern towhee and the purple finch. The property offers excellent conditions for wood turtles. The Thomas and Palmer Brook corridor has been identified as core habitat by Natural Heritage, meaning it is a habitat that could have rare, vulnerable, or uncommon mammal, bird, reptile, amphibian, fish, invertebrate, and plant species.

      A habitat restoration project in 2018 and 2019 removed invasive species in the apple orchard and surrounding area. The Whale Rock feature is a metamorphic rock, which formed from high heat and pressure during the mountain-building process 540 million years ago.
