The Long Pond Trail at Pfeiffer Arboretum offers a quiet 0.7-mile walking loop through diverse forest and wetland ecosystems. Forest management and invasive plant species control efforts are underway, helping to preserve the abundant native plants. The spur trail offers views of Long Pond. The trailhead is located at 249 Long Pond Road. From Division Street, go .6 of a mile to the trailhead. There is a sign and informational kiosk. Parking is limited. Please be considerate of the neighbors.

In 2017, new bog bridges and boardwalks were installed, using black locust timber harvested from the Lake Mansfield Conservation Forest and donated by the Town of Great Barrington. This project involved 14 teens from Greenagers, 3 crew leaders, and one director. Volunteers contributed 119 hours of work. Together, the volunteers and crews removed rotted walkways and installed the supports and beautiful hemlock boardwalk, stone steps, and other beautiful features. Invasive species plants were removed and new native plants were added.
