The only time of year you don't want to take this winding 40 mile canyon road is the WINTER. It's not wise under any circumstance. Not even with chains. This is a two-lane highway, narrow, winding and twisting as it goes from Sedona to Flagstaff in the north. The best time of year is in October when the leaves change and the color is breath taking. The canyon draws plenty of people and it gets nasty when some recreation vehicle decides to do it. It slows traffic way down. It's not for rec vehicles. Take your car, not your RV. Take your camera and video cam. The views are stunning. Stop at Grasshopper point, park and shoot. Stop at West Fork Trails providing there's parking room. Take the half mile hike into some of the most beautiful Nature you'll ever see. This is a slow drive...35 mph down to 20 mph or less depending upon the hairpin curves. Be prepared for a leisurely drive. It's a secondary way (other than taking I-17 north from Sedona) to reach Flagstaff. It's actually faster to take Oak Creek, but (again) you get these unnerving, large, unwieldy RV's on this highway and your time is blown. So, if you're needing to make an appointment in Flagstaff, take I-17.
