About Grindstone Falls
Grindstone Falls is a quietly scenic waterfall in Maine tucked into the Penobscot River Corridor. Nestled on private land and managed as part of that corridor by SPR, it’s a lesser-known spot that rewards visitors with wooded approaches, mossy rock ledges, and a peaceful plunge pool—perfect for a reflective picnic or a photo stop away from busier trailheads. Because the falls sit on private property within the Penobscot River Corridor (designation: UNKE), visitors should respect access rules and stay on established paths. The short but rewarding approach makes Grindstone Falls a great choice for hikers seeking a moderate outing with classic Maine river scenery rather than a long day on the trail.

Note that the fall and access route lie on private land within the Penobscot River Corridor managed by SPR—observe any posted access restrictions and stay on the established trail.
