The winding Armstrong Trail traces the course of the scenic Allegheny River along the former Allegheny Valley Railroad line. More information can be found at www.armstrongtrail.org. The Trail begins by the confluence of Crooked Creek and the Allegheny River by the village of Rosston (Mile Post 39). Starting at Rosston you share a road for 1/2 mile before going onto crushed limestone. Asphalt starts in 2/10 of a mile and continues for 2 miles. A road detour takes you through Manorville. North of Manorville the trail is asphalt and crushed stone for the next 3 1/4 miles to Mile Post 46. At mile post 46 the trail continues as a compact stone surface to Mile 57.8. A 4 block detour is in the village of Templeton.
