About the Reserve
A Protected Landscape Serving the Community Since 1987
Greenfield Park & Nature Reserve was established in 1987 following a land conservation initiative by the Millbrook Town Council. The reserve protects 340 acres of mixed hardwood forest, open meadow, and freshwater wetlands in the eastern section of the town.
The reserve sits within the Greenfield Creek watershed, which supports a documented population of over 140 bird species, including several wetland-dependent species of conservation concern. The landscape includes three distinct ecological communities: upland oak-hickory forest, floodplain silver maple forest, and emergent marsh.
Management of the reserve is carried out by the Millbrook Parks & Recreation Department in coordination with the Massachusetts Division of Conservation Services. Long-term stewardship plans are reviewed on a five-year cycle with public comment periods.

FAQ
Frequently Asked Questions
Common visitor questions about access, rules, facilities, and programs at Greenfield Park & Nature Reserve.
Contact the Visitor Center for further information →Is there an entrance fee to visit the park?
Greenfield Park is a public nature reserve maintained by the Millbrook Parks & Recreation Department. Access to the main grounds and trail system is available to all visitors. Certain permitted events or organized group activities may require advance registration through the department.
Are leashed pets permitted on the trails?
Dogs and other domesticated pets are welcome throughout most of the park provided they remain on a leash no longer than six feet. Owners are responsible for removing waste using the station-supplied bags located at major trailheads. The Wildlife Observation Area near the eastern wetlands is a pet-free zone to minimize disturbance to nesting species.
What restroom and sanitary facilities are available?
Fully accessible restroom facilities are available at the Main Visitor Center (open daily during park hours), at the North Picnic Pavilion, and at the South Trailhead parking area. Portable sanitation units are placed seasonally at the Overlook Meadow during high-traffic periods.
Are campfires or open flames permitted?
Open fires, including ground fires and wood-burning devices, are strictly prohibited throughout the reserve. Two designated charcoal grilling stations are available at the North Picnic Pavilion on a first-come, first-served basis. Portable gas grills under 10,000 BTU may be used in designated picnic zones only.
Is the park accessible for visitors with mobility limitations?
The main entrance path, Visitor Center, North Picnic Pavilion, and the 0.8-mile Meadow Loop Trail are fully paved and wheelchair accessible, meeting ADA standards. The recently completed Wetlands Boardwalk also provides barrier-free access to the eastern viewing platform. More rugged terrain trails are not yet fully accessible; signage at each trailhead indicates accessibility ratings.
Are ranger-led walks or educational programs offered?
The Greenfield Park Ranger Program offers guided interpretive walks on Saturday and Sunday mornings from April through October, departing from the Visitor Center at 9:30 AM. Topics rotate monthly and include local flora identification, migratory bird observation, and wetlands ecology. Group bookings for schools or organizations can be arranged through the Millbrook Parks & Recreation Department.
Is swimming or wading permitted in the park's water features?
Swimming, wading, and entering any of the park's ponds, streams, or wetland areas is not permitted. This restriction is in place for visitor safety and to protect the ecological integrity of the reserve's aquatic habitats. Fishing with a valid Massachusetts fishing license is allowed at the designated Willow Pond fishing area.
What should visitors prepare before their visit?
Visitors are advised to wear weather-appropriate, layered clothing and sturdy closed-toe footwear. Bringing sufficient water is strongly recommended, particularly during warmer months. The Visitor Center maintains a printed trail map; digital maps are not reliably available due to limited cellular coverage in parts of the reserve. Insect repellent is advisable from May through September.

The West Meadow Trail and all accessibility paths remain fully open throughout the work period. Visitors are asked to observe posted closures and avoid unmaintained sections.
Migratory Waterfowl Season Underway at Willow Pond
The annual spring migration has brought an early influx of wood ducks, common mergansers, and hooded mergansers to Willow Pond this season. The eastern observation blind has been cleared and restocked with spotting guides. Visitors are reminded to maintain a quiet approach and keep a minimum distance of 30 feet from the water's edge.
Wetlands Boardwalk Scheduled to Open This Summer
Construction of the 340-foot accessible boardwalk through the eastern wetlands section is progressing on schedule, with an anticipated opening in late June 2026. The structure will provide barrier-free access to two new wildlife viewing platforms and connect directly with the Meadow Loop Trail. Funding was approved through the Massachusetts Recreational Trails Program.
