There are warning signs on Hwy 14 '8% grades, 25 mph curves' The eastbound descent has 6-8% sections; one section is 3-1/2 miles long and another 4 miles long. Then you'll have 2-5% grades. You'll have 23-1/2 miles of downhill. It's not an easy drive. I'd suggest for Cedar Breaks to stay in Cedar City and do a day trip.
Actually, Cedar Breaks is o.k. but on a bigger, grander scale, go to Bryce Canyon National Park nearby. Cedar Breaks is a mini version of Bryce.
If you're coming from I-15, to get to Bryce exit at Circleville and take Hwy 20 to Hwy 89. Hwy 20 is good for RVs. Head south on 89 through Panguitch to turn east on Hwy 12. All good roads. Ruby's RV at the Bryce entrance is probably the best place to stay if you need hookups and in October you might want them. Otherwise, stay in the park itself but no hookups. The hiking down below in Bryce Canyon is awesome. It's like walking in a fairy wonderland.
Remember...there are other great national parks in this area - Zion, Capitol Reef, Arches and Canyonlands along with Monument Valley and a little way into Arizona - Grand Canyon. Lots of beautiful scenery and October is the perfect month to see it.
