Keystone Arch Bridges

"It's an easy family activity with magnificent sights and history! The path of the trail can be a little confusing as it tries to avoid the railroad right-of-way, but if you just keep going in the direction you think you should you'll get there anyway. Personally, on the way back I find the gravel rail access road pretty interesting but I doubt that the rail operators agree. You might think, hey the first 2 bridges are missing! No, they're just hard to reach. You get a view of the first one not far from the parking areas with a secluded path down to the river. To actually get on it you have to cross a scary bridge with no margin or bushwhack a bit. This bridge is still in service, so best to stay off it. The next hidden bridge is petite and hard to spot. See the image. As you are outbound, the trail meets a wider trail on the left and the wider trail doubles back the way you just came from. See green arrow. You have to cross the active tracks. The first bridge you encounter on the proper trail is incredible. The trail makes a tee at an informative "you are here" sign. Before continuing right, check out the bridge to the left! Popular swimming spot but the way down to the river is VERY steep. After you cross the bridge, there is a secret blasted railroad cut you can easily bushwhack through. Neatly intersects the current railway. See image. If you are a bushwhacker like me, there is an interesting spot that is cut off by the river and the railroad. See photo, use a map to spot this location, not far from parking. You can find the remains of a sluiceway, overshot water wheel, and many building foundations. It's the site of an 1856 saw mill, and more interesting, an 1873 "Shoddie Mill" also spelled "Shoddy" depending on the era. You may recognize the word as meaning something poorly made. In this context the word is referring to the recycling wool. Old and remnant finished wool goods are shredded into Shoddie and re-formed into blankets and other things. You may be of an age to remember wool felt blankets that were so itchy and horrible you'd rather freeze. Walk the giant green path in the image. Also of interest in this same area is the large clearing shown with historic building locations and water features drawn on. The long story of this place ends with art, treachery, lust and murder! And a big pottery kiln, still there. Too much to cover here."

"Completed the Keystone arch bridges trail today. A very well marked and fairly easy trail of 2.5 miles to the end and then back. There are informative signs about the bridges and the railroad that once went over them. Although the bridges and the railroad cutouts are the draw here, the river is nice and the trail goes along the river for the most part. I think when there isn't a drought there are a couple small brooks and waterfalls that the trail crosses."

"Awesome morning walk. Unfortunately, because fallen foliage is hiding the path, there aren't enough trail markers to be effective! Lots of new markers, but not enough, especially at turns... Great walk though."

"Nice hike with interesting history. It's an easy hike. There is about 600 feet of total elevation gain over the 5 mile hike. If you have limited mobility it would be tough due to uneven ground, sand and rocks on the path. The river and woods are pretty and the arches are a nice bonus. We enjoyed even in the rain."

"I sometimes steer clear of out-and-back trails, but I'm glad we tried this one. The stone bridges towering over the river are very impressive, but even without the bridges, the river views are spectacular. This route gains a modest amount of elevation going out, as the path travels upriver. The trail is mostly easy walking, often wide enough for two people to walk comfortably side by side. Some sections are a bit muddy. In one section, the trail turns right, narrows and gains a bit of elevation before a footbridge crosses a cascading stream, then winds down to follow the river again. There are a few opportunities to venture off the main KAB trail (blazed with blue metal tags); these offshoots can provide the best views of the bridges. The bridge toward the end provides a great view downriver for a lunch break."
