Scenic Roads in Utah and Arizona
These are some of my favorites -- if you get over this way, you might try to include some of them. I limited the list to roads in the northern parts of the state (AZ) as that is where you said you'd be traveling. Bob
Utah:
SR14 and 143 east of Cedar City;
SR12 from Bryce to Torrey;
SR24 from I-70 to Hanksville;
SR95 from Hanksville to Mexican Hat (using SR261 cut-off);
US191 south from I-70;
Be sure to see as many of the southern Utah parks as you can.
