The City of Framingham acquired part of the Macomber Estate, known as Raceland, in 1971 for conservation purposes. This 57-acre parcel encompasses meadows, wetlands, and upland forests. The north border is Stearns Reservoir Number 1 of the Sudbury River, which is maintained by the Massachusetts Water Resources Authority.

Barton Brook, a rocky babbling stream, runs through the property creating beautiful wooded wetlands. Barton Brook splits in the middle of Macomber (an unusual phenomenon); one branch drains to an emergent marsh and the other runs merrily down to the Reservoir.

The AllTrails website has a description and map of a hike at the Macomber Estate.
