>>910413There are none in that area really.
OP I'm from SF and have traveled extensively around all the areas you are going to. Where are you staying? I organize my trips around where national forest/monument areas are since I have an off road truck and just dispersed camp everywhere I go. If you are trying to stay in hotels or can't go off road then my suggestions would be different.
Definitely go Southern Utah as has been suggested (Zion is good, I also liked Escalante (check out Lower Calf Creek Falls if you can make a 6 mi hike), Brian Head area, Bryce, Canyonlands and Moab for offroad are good. Route 50 from Colorado to California is a very unique highway, very empty, I'd try to go from UT to South Lake Tahoe area on that route if you can. Check out Downieville CA and the surrounding area, hidden gems eveywhere. What are you really looking for, great hikes? Good driving roads? Be specific and I can tell you some good spots.
