Arkansas SR-7 SB from Harrison, AR to Hot Springs, AR

I have driven this route several times, with and without our 34' fifth-wheel. I do not consider it risky at all. On the other hand it is "curvy and hilly," and that amounts to a much slower route. If you have the time and are willing to enjoy the drive, I would recommend it.

EDIT to add: I have found most Arkansas state highways to have good surface and pleasant to drive but many of them are "curvy and hilly" like AR 7 and are not the fastest routes.
