Sedona to Flagstaff driving

Question

I’m going back and forth if I should drive from Sedona to Flagstaff and back via 89A or I17 and 179. I’m reading contradicting stuff online. Can anyone clarify this:

1. Is there cliff driving without guardrails?

2. I’ve never driven in significant elevation change like this. Does it make you feel dizzy or anything while driving?

Thanks!

Answer

Driving between Sedona and Flagstaff gives you a choice between two main routes: via Highway 89A or via the combination of 179 and I-17. Both offer scenic views, but they differ in driving style and comfort, especially for those not used to elevation changes and winding roads.

Route options:

Highway 89A: This is the classic scenic route. It’s a two-lane road with winding sections, hairpin turns, and significant elevation change as it passes through Oak Creek Canyon. The road is well-maintained, but in some places the drop-offs are steep. Guardrails are present in many areas, but there are sections where they are minimal or absent, so caution is needed, especially if you’re uncomfortable with heights.
179 + I-17: This is a faster, more conventional route. You take 179 north from Sedona to connect with I-17 north to Flagstaff. I-17 is a multi-lane interstate and much easier to drive; it handles the elevation change gradually, and there are no cliff-edge sections without guardrails. It’s less scenic than 89A but safer and less stressful for drivers not used to mountain roads.

Cliff driving and guardrails:

On 89A through Oak Creek Canyon, you will encounter some sections with steep drops and minimal guardrails. Most drivers navigate it without issue, but it can be intimidating for those sensitive to heights.
I-17 and 179 are generally safe, with proper guardrails and wide lanes; you won’t have cliff-edge driving as on 89A.

Elevation and motion effects:

The elevation change on 89A is more abrupt and includes tight curves. Some drivers report a mild dizzy feeling or disorientation due to constant turning and ups-and-downs, but it’s generally manageable if you drive slowly and take breaks.
I-17 has gradual elevation changes over longer stretches, so most people find it comfortable and easy to drive, even if you are not used to mountains.

Recommendation: If you prioritize scenery and don’t mind slow, careful driving with occasional cliff views, 89A is the classic choice. If you prefer safety, wide lanes, and less stressful driving, especially if you are concerned about dizziness or heights, take 179 + I-17.

Regardless of route, allow extra time for photo stops, check weather conditions (fog or rain can make 89A more challenging), and drive at a comfortable speed to enjoy the views safely.
