Bluff, Utah
Then up towards Moab, cut over to Capitol Reef National Park, to Torrey, Utah, and then Hwy 12 to Cedar City. The most incredible highway I've ever driven. Be sure to stop at the wonderful cafe in Boulder and get your free wifi fix at Escalante Outfitters in Escalante. The pizza there is very good too, and the owner and staff are good folks. They also have camping available or spartan but new "camping cabins" which I've stayed in.
I have a thread in The West forum about some road-trip routings you might find helpful.
You also might ask the moderator of this forum to move this to The West Forum where it would be more apt.
