State route 89A from Flagstaff to Sedona

There is a sign just before you drop into the canyon stating 50' limit. Don't know how well that is enforced, but would be a long trip back if you were not allowed to go thru. And the curves, switchbacks, and narrow highway mean there are places where you will be taking up your lane and part of the oncoming lane. Or scraping the rocks along side.

I went down 89A to Sedona towing a 32-foot fifth wheel with no problem--I just used ordinary care by taking each curve at the recommended the speed and swinging wide to keep trailer wheels inside my lane. As you near Sedona there are likely to be a lot of people walking along (and in) the road, so watch out for them.

The posts above describe the route fairly accurately except for a couple of points. First, and most important, the route is restricted for TRUCKS over 50'. I've checked with ADOT and use by RV's, either towed or Class A's or Class C's is not restricted although it is not recommended. Read the signs CLOSELY. This applies to 89A from FLagstaff to Sedona and also from Clarkdale to Prescott. I have run both segments in a large Class A pulling a pickup toad and the route is tight, but doable. On the Flagstaff to Sedona section if you are going south, the route is easier to drive than northbound. The segment along side Oak Creek has a fairly high road crown and if northbound the cliff's on the right are very close to the shoulder. Unless you are careful, it's possible to clear the lower parts of the cliff but hit the upper area or awnings while fully in your lane. Southbound you will see some cliff faces to your right on the hairpin turns, but clearances are not as tight. Overheated brakes and transmissions are possible so if you have a compression brake or Jake brake, use it and control your speed. There are occasional turnouts on both 89A segments, but you'll probably pick up a line of traffic behind you between turnouts. Traffic through Jerome on the southern segment can be tight and busy in tourist season. People don't expect big rigs. There are no runaway ramps on either segment.

We did it in 1999 pulling a 24ft TT. Make sure you're breaks are good and take it easy.It's a beautiful drive.

I drove that road dozens of times in a 45' motorcoach. Nothing to it.

I guess it depends on the person, I took a 30' class C motor-home to the top of Pike's peak. Just need to look ahead so you can swing wide on the narrow switchbacks
