I haven't been on it in a couple years, but I commented on how there was a surprising amount of compact rental cars on it. I'm not sure how they were getting past a certain spot. It might be a different story if it was really wet.
I did it in a 2wd Pathfinder. Like Paul said, it's bumpy. Take it slow and you'll be fine. It's one of those roads you need to do at least once. Best is from I-17 to Sedona for the views coming in. There are a lot of nice hikes off that Road
There is a very fine line between "hobby" and "mental illness."
Funny you mention that, Jim was literally just up there, he drove bike up with his daughter, opted for Jeep rental, but they were very happy they went that route..I guess he said not a road for Harleys..lol..but he said in a pinch he could have done, but it would have been slowwww going....
If you are planning on driving schnebly road in anything that's not high clearance... Use the most current report you can get as condition may change with every rainfall. Only takes one real rough spot to make you turn around or go when you should not have.
Monday, Tuesday, Wednesday, Thursday, Friday, Saturday......there is no SOMEDAY!
