Concord, Massachusetts
Great Meadows Refuge — Concord Unit

Two big man-made pools with a dike trail between them, a lookout tower by the parking lot, and a refuge bird list of over 220 species. No dogs allowed.
Written for ages 3–12.
Researched from this park's own sources. Nobody's walked it yet.
Read this bit out
These two big ponds were not always here. People built walls to hold the water in on purpose, to make somewhere for birds to stop and rest on their way past. More than two hundred different kinds have turned up. The path we are walking on is the wall.
One of your three free places, or the Explorer Pass. What that costs
Before you go
- Time there
- Plan on about an hour and a half at the park.
- Parking
- Take Route 62 east from Concord Center for about a mile and turn left onto Monsen Road. There's an entrance fee, paid at a self-pay station in the lot. Open sunrise to sunset, year round.
- Underfoot
- Four trails making 2.7 miles, almost no elevation change. The observation tower is right by the parking lot and the Dike Trail runs between the two impoundments.
- Stroller
- A stroller works on some of it.
- Food
- No picnic areas and no fires. Carry out any trash.
