We live I Buena Vista and travel over Cottonwood Pass a couple times a year. As you probably know, the road is paved on east side to the pass. The other side is an all weather gravel county road. There are some fairly tight curves near the top going down on the west side. But you are above tree line and good line of sight. There are a few blind corners after you get down into the trees.
The road can be really wash boarded in places. Haven't done it this summer. Also can be a real gooey mess if it rains. Just take it nice and easy. Main roads in Taylor Park are gravel county roads. Again, they can and usually are very wash boarded and dusty when dry.
Don't miss the homemade pie alamode at the restaurant/campground. Can't remember the name.
