  • The mill is impressive and unusual since it uses vertical turbines instead of a wheel. There is lots of equipment inside for processing grains. It is a picturesque place with the falls, mill and covered bridge. There are nice walking trails along the river. Parking at the mill is very limited. The best is to park at the lots above and walk down.
  • I've been going to McConnells Mill ever since I was a kid but I feel like I've yet to see it all. For a summer outdoors destination, McConnells Mill is a perfect spot to explore trails, rock climb, see glacial rock shaped by the ages, enjoy the relaxing sound of the rivers rapids, encounter wildlife and more. This is a place to bring the family and it has something to offer explorers from novice forest goers to more advanced adventure seekers.
