Hall’s Pond is one of two natural ponds remaining in Brookline. The sanctuary contains diverse ecosystems including a pond, wetlands, an upland area, a formal garden area, and a short trail around the pond with wetland overlooks. The sanctuary has undergone major landscape renovation featuring restoration in the uplands to remove invasive plant species and replant with native species.
