The Ouaticha Mountains stretch from Oklahoma into Arkansas (or I guess you could say they stretch from AR to OK) and there are numerous great roads in and around the mountains. The most well-known is the 50+ mile Talimena Scenic Byway. There are other lesser known roads that provide great views and an ample amount of twists and turns.
US 259 bisects Oklahoma SR 1 a.k.a Talimena Drive and runs north ending at US 59. US 59 parallels the Talimena Drive on the north side of the mountains from Arkansas until the US 259 intersection and then it turns north towards Poteau, OK.
