The Lake Mansfield Recreation Area is a community natural resource area featuring a 29-acre pond and the adjacent 29-acre Conservation Forest with a 1/4 mile easy walking loop trail. The area is a vital natural habitat and treasured community space. Visitors are responsible for their own safety and must be mindful of their impact on the delicate habitat and the enjoyment of others. The Lake, Beach Area, and Conservation Forest are owned by the town of Great Barrington and overseen by the Parks and Conservation Commissions. Stewardship is provided by Lake Mansfield Alliance with this community vision in mind:

We see Lake Mansfield as a protected ecosystem within Great Barrington where people, wildlife, and nature can coexist in a symbiotic relationship. The water is pure and free of exotic invasive plants. The native aquatic plants provide nourishment to fish, birds and wild animals. There is a natural buffer zone that surrounds the lake and the habitat there filters runoff and supports local wildlife.

The Lake Mansfield Improvement Planning Task Force works with the Town Planner to advise the Selectboard on the next steps needed to provide improvements for the Lake Mansfield Recreation Area that will support the health of the environment and provide safe access and recreational opportunities for all. See: Improvements at Knob Hill.
