Tredway Trail
The Tredway Trail in Allegheny Township, Pennsylvania is an easy 4.4 mile out-and-back trail that leads from the end of Boggs Way and runs along the Allegheny River until the trail reaches River Forest Drive and McCane Hollow Rd.The trail is flat, wide, well-maintained, and lightly-trafficked with a few different view points of the Allegheny River and the surrounding hills on its banks. Further down the trail, around mile 1.9, you can find a nice view of the river with a bench along the trail - the hills across the river are actually Harrison Hills Park, where the Scout's Trail runs along the edge.
Around mile 1.3 you'll find a creek that runs down a rocky ravine, passing under the trail, and out to the Allegheny River. You can walk down a tiny trail to a pool where water fills up before it runs through a pipe under the trail. There are some small, 2 to 3-foot waterfalls along the creek in the ravine. A pair of benches can be found here as well.
At mile 2.2 you'll reach an intersection with McCane Hollow Rd where the Tredway Trail ends; however, there is a trail that continues north along the Allegheny River for many miles, which is part of an extension plan project to extend the Tredway Trail an additional 1.5 miles to the Freeport Bridge.
Parking: Directions to parking can be a bit confusing as Google has not mapped the entirety of Boggs Way in Allegheny Township. Follow Google's directions along Bogg Way until it says you've arrived - continue driving down the dirt road until you reach the parking lot for the trailhead at the end of the road.
