Following the blue-blazed trail, this hike begins at the historic Lock 12 of the Susquehanna Canal then heads south for a quick loop on Peavine Island. Access to Peavine Island is seasonable and a section of the trail can at times be under water. If this is the case, continue heading north on the blue-blazed trail back under the Norman Wood (blue) bridge along the Susquehanna River. The trail then turns left to River Road by an old saw mill. Cross over the bridge and take an immediate left to head up Mill Run. Enjoy the beautiful waterfall views surrounded by rhododendron with a gradual incline. When the trail begins to head right and you see a fork, take the right and use the switchbacks to climb up the trail towards the power lines. Great views of the Susquehanna River, the Norman Wood Bridge, Holtwood Hydroelectric Plant, and Lake Aldred along this stretch with two overlooks.

Liked this trail a lot! Pretty challenging terrain with multiple hills, but also some good spots for running. Mostly shaded, and stretches along running water with pretty rhododendrons. Last bit was just an uphill grass walk for about a half of a mile, which wasn’t my favorite. But other than that good hike!

The hike had some awesome views and places to take a dip in the water! Had an overall enjoyable hike which took about 5 hours to complete. The end of the trail was a gradual incline with high grass and the top didn't have the cool view I was hoping for (unless I missed something). Would hike again.

Amazing hike. Lakeside / falls / ferns + rhododendron forests / bamboo / some nice views and chance to see some birds of prey. River crossing. Another beautiful falls section. Some evergreens. Really fun out and back - took me 5 hrs though the last uphill old forrest road end section could be skipped unless going to a car in north lot, Ended up being ~ 11 miles total. Pretty underrated - kinda stumbled upon it (much better than Kelly’s Run / Pinnacle trails across the river). Echoing others - bring bug spray. One of my favorites in eastern PA so far

Really nice hike with interesting views along the way. Historic canal lock, rhododendrons, waterfalls and a couple of high points with nice views, especially this time of year with most of the leaves off of the trees. Trail is also well marked.

Really beautiful trail along the Susquehanna. It gets treacherous on some turns but the views are amazing over the roaring river.

A fantastic trail! We hiked about 3/4 of it before we turned back (had to beat the school bus home). It was definitely challenging in sections, but rewarding! There was something interesting and beautiful to see around every corner. We ran into a few volunteers clearing fallen trees in preparation for an event in early September--clearly the trail has some devoted caretakers. It was mostly shaded, with some level areas, and plenty of steep climbing up and down. Fairly rocky paths (we like that), sometimes very narrow. Well-marked. A couple excellent outlooks. Will be fantastic views after the leaves have fallen. Just a few tips: It rained a few days ago and some of the rocks were still very slippery, so be extra careful in steep areas if the trail is wet. Wear really good shoes with ankle support and soles with good traction. We also ran into some bees at higher wooded elevations (toward the far end of the trail). There were restrooms near the parking area. It took us about 2 hrs to hike out about 3/4 of this trail, and about 1.5 hrs to hike back. Had a fantastic time and hope to visit it again soon!

The views of the many waterfalls alone make this trail phenomenal. Completed it on Saturday & went fishing on Sunday. Great weekend!

Good tough hike. Took about 6 hrs round trip. The turn around point is at the beginning of the hunting road at the top of the climb through open grassy area.

This is one of my favorite local trails so far. There are many interesting features along the trail (the old lock system, the river, lake, dam, remains of old retaining walls, beautiful flowers, and many species of butterflies.

With a little effort, we managed to climb through the fallen trees and walk in the rocks/dead trees upstream the river past the lake. The view and listening to the water were both very nice.

It is a little on the difficult side, but I recommend it for families. There are many insects, birds, and small snakes along the trail for the kids to observe (and be amazed).

For being the day after a hard rain, it was humid but the shade helped. First time there and we tried that island loop south of the bridge. Saw several downed trees on trail. Seemed sparsely used but great views and awesome rock formations plus incredibly still-standing stoneworks that are +/- 200 years old. Canal Lock 12 is a must-see. We then went a short hike up the M-D trail north of the bridge and made that first left turn. It climbs a beautiful stream valley complete with beautiful falls all the way down. Look like some great pools you can easily wade in and cool off. We'll definitely be back and check out the full upstream Mason-Dixon system.
