Did this as part of my Owls Head hike. Lincoln Woods Trail is super wide and easy to follow, but with very little to see other than some outlooks on the river. After the first 3 miles you’ll see a bridge and a side trail, take the side trail. After a short walk you’ll see the falls. The trail seems to continue off into the distance after this, I’m not quite sure where it leads. The falls have one narrow spout and a couple small cascades that connect different pools, they aren’t very deep but you can definitely swim here even in low flow. Definitely worth a visit if you’re in the area.
