Mike,
Cottonwood Canyon Road is one I use frequently, as in good weather it provides a useful and scenic shortcut between U.S. Hwy 89 and Utah 12. There are some great hikes along the way, and of course the country is beautiful. Be warned however, as the road is one of those backways that becomes a trap for the unwary when it rains - See the link for the "Impassable when wet" below.
