Grindstone Falls Trail, Grindstone Township


  • Preserve Size: 4 acres
  • Trail Mileage: .9 miles one way
  • Pets: yes
  • Difficulty: easy
  • Sights: Penobscot River East Branch

This is a nice walk along the Grindstone rapids in the East Branch of the Penobscot River. When I walked it in March 2017, the trail was unmarked except for some plastic tags tied to branches. Nonetheless, the .9-mile path was easy to follow.

The best place to park is at the Grindstone Falls picnic area, nine miles north on Route 11 from Medway. Then you walk back along the road, going south, about 500 feet where you’ll see the path on your right. It follows the river for about .8 miles or so where it crosses the road again. You do a short jaunt in the woods here and then come back out on the road.

More info on Maine Trail Finder.

Directions: From Medway, go north nine miles to the picnic area on your left. Look for the trail 500 feet south of the picnic area, on the river side.
