Description Suggest change

This is a small collection of boulders in Ayer, MA (35 miles northwest of Boston). I first came across this area in 2006. While I don't think that I was the first one climbing there, the lack of chalked holds suggests that it is rarely visited for climbing.

Given the rather small selection of problems, the area seems most suited for local climbers who are looking for some nearby bouldering.

Getting There Suggest change

From Ayer center (NW of I-495 and Route 2), take Washington St. north towards the Nashoba Valley Medical Center. Once you are at the power lines, park on the right (east) side and follow the trail under the power lines. The first good boulder is atop the hill on your left. To get to the Double Roof, follow the trail down the hill and take an immediate right after getting into the woods.
