The whole journey from 79 to Oakdale is what's good to ride. Just turn around in Oakdale and hit it up reverse.
Scenery
At one point there is a small cliff overlooking the road and opposite of that is a creek maybe 20 feet wide. Other than that, the main views is of the woods and the various scattered houses along the route.
The road isn't too much about the scenery, but it isn't a eye sore by any means.
Drive Enjoyment
Several actual 'hairpins' along Noblestown, so be aware. The road has some rolling elevation changes with a few steeper inclines coming in and out of a couple turns.
there are some other tighter turns coming in and out of the hairpins.
The road is relatively narrow for a 2 lane road, but it's not a problem. There is no real shoulder on parts, especially where it gets real twisty.
The pavement is rather smooth with minor blemishes making for a confident ride. (It get's covered in leaves in the fall so watch out depending on the season)
Tourism Opportunities
restaurants in the 2 towns on the ends of the road, and gas stations in Carnegie
Motorcycle Road Additional info
