The Presque Isle River loop hike follows both banks of the Presque Isle River. You can start at either the road bridge or the suspension footbridge down by the lake. We did the east side first. There were a couple of dicey spots where the trail was washed out or there were lots of roots, but it was generally decent, with beautiful views of the river. We then crossed at the road and did the west bank. There were some boardwalks and steps on this side, and a spot where it looked like the original trail was washed under so they had to reroute it, which meant some backtracking to view different falls. All in all, we thought the west side easier, and there were more people too. Less babbling for bears on the west side.
