There's much more than 3.7 miles of trails here (I regularly do 4.5-8 mile loops here) AND you can connect with other nearby trail systems. Great place for short or long easy hikes/walks, bird watching, bike rides, snowshoeing, cross country skiing, hunting, fishing, and looking for tracks. Most trails are either flat dirt trails, partially paved old roads, or you can just walk the sidewalk if you have strollers or unsteady-when-standing individuals with you.

ARNWR was once a part of Fort Devens/Maynard ordinance depot and the historic ammo bunkers are still standing. The visitor center is open from 10a-4pm on weekends and is a great place to check out (especially with kids)!

Fair warnings:
This is a great find for locals & new hikers/outdoor enthusiasts BUT if you're looking for a physical challenge, you won't find it here.

The refuge boasts a large wetland and while this is ideal for wildlife viewing, during the summer it can get VERY buggy on the trails.

Dogs are not allowed on the refuge.
