From Wye (intersection of Highways 113 and 300), go southwest on 300 and end at Hwy-10 in Pinnacle, AR.
This road begins going east with a three-mile straight stretch of canopied road, then after another mile or two, it turns south/southwest, where the curves begin. You'll feel like you're riding through a hidden forest. It's actually nicer to slow down a bit to enjoy this route. Overall, this route has lots of shaded road, especially in the first three miles (canopied).
An older road, but generally in good shape.
Really no amenities on this route however, towards the end, you'll go past Pinnacle Mountain State Park.
While a nice ride, be aware that while many roads have a regular rhythm to the curves, not this one. You'll do a long, straight section, followed by extremely tight curves, then straight again. It can take you out of your rhythm and make it easy to over-power the curves.
