What kind of car, AWD? The National Parks, IMO.... Southern Canyonlands is neat, Deadhorse Point for views (but this smoke may kill that). Drive the La Sal Loop road, it's pretty neat.... but the fire in the La Sals may effect what's open?
If it’s open, the LaSal Loop Road is a scenic drive. It starts near the old airport south of Moab and comes out in Castle Valley. You could also drive Hwy 128 out to Cisco, Hwy 279 down to the Potash Boat ramp (possibly even continue up the Shafer Trail), or Hwy 313 out to Dead Horse Point. You could even drive through Sandflats and connect in with the Loop Road depending on the car you’re in. It’s generally a graded gravel road with a few washboards.
We ended up hitting Sand Flats early and did some walking around, brought the kids by the petroglyphs and Dino tracks on Potash (my daughter couldn't remember seeing them (she was littler)), doing lunch at Milt's and hanging out by the pool (their highlight).
Thanks for the suggestions, if it was clearer/fresher air, I probably would have done the loop. I got voted out of any car trips promptly.
All in all it was good to get out of the air in the valley. It wasn't perfect but it was better, for sure.
