Best Motorcycle Roads in Ohio

OH 555 "The Triple Nickel"
This is the quintessential road that everyone talks about. It is almost a "Right of Passage" for riders in the area.
As a matter of fact, people travel from all over to experience this stretch of scenic southern Ohio. The road gives you challenges with tight twists and "reverse-camber" turns through this 62-mile road covering four counties in Southern Ohio! There are a few places to stop, but the ride is exhilarating and causes you just keep rolling!
This is one of those roads that everyone talks about riding, and you should be able to tell the story of your own experience!
State Route 555's southern end is at US 50, SR 7 and SR 32 (James A. Rhodes Appalachian Highway) in the community of Little Hocking in extreme southwestern Washington County. This part of the journey is nestled in the Ohio River Valley and provides scenery as you exit the Triple Nickel.
Its northern end is at SR 60 in Wayne Township, just outside Zanesville. If you are ending here, the road leaves you heading into the historic city of Zanesville (once the capitol of Ohio) and to the very unique "Y-Bridge" on Rt 40, also known as the National Road. Either way that you take 555, you will NOT be disappointed!

St Rt 374 in Hocking Hills
If you love rolling hills and scenic stops, you MUST take St Rt. 374 off of Rt 33 near Rockbridge and prepare yourself for pure enjoyment! The road takes you right into the Hocking Hills region where you can explore this amazing area of cliffs, waterfalls, hiking trails and amazing camping! You can follow the State Park signs to many of the attractions including Rock House, Cantwell Cliffs, Conkles Hollow, and even Old Mans Cave, just to name a few. 
You can take 374 to the end and then take 664 to a favorite biker stop at Jimbo's Burgers and Beer (drink responsibly) and then you have a slew of other roads to experience!

Clear Creek Valley
Although this road does not have the best surface conditions, it ranks right up there with scenery! You find yourself drifting alongside a crystal clear river on one side of you, and a lush forest on the climbing hillside to the other. It is a spectacular ride all year long, but breathtaking in the fall! There are numerous places to stop and enjoy the area. Clear Creek offers many activities, including hiking, picnicking, canoeing, fishing, nature programs, and a pet trail. The mass of the area was donated to the Columbus Metro Parks system and is the only park that is not in Columbus proper.
