We travelled the Kebler Pass in early October and found the views to be beautiful. The road is smooth packed dirt for the most part, although there are several short sections where it's paved. It's easily driven by car, but if you turn off on some of the side roads, like Ohio Pass, you may want to have a higher clearance vehicle as the roads are narrower and a bit more rutted. That said, Ohio Pass is worth a look as it offers great views. Be aware that the whole area has free range cattle roaming the roads so be careful around turns.
