Classroom Rock is a shallow freshwater navigation dive off Pontoosuc Lake.
Shore access from the fishing pier, a shallow lake route, and summer boat traffic make Classroom Rock best for careful freshwater dives.
About Classroom Rock
Classroom Rock is a shallow freshwater dive on Pontoosuc Lake, reached from the fishing pier by following submerged logs and boulders. It is more of a navigation exercise than a big-structure dive, which makes it a good classroom-style site for practicing line-finding and buoyancy. The site works best when you keep the route simple and watch the lake traffic around the pier.
