There’s a reason “taking the high road” is not considered an easy task. Have you ever driven a mountain road? Some of them, including those here in Arizona, are often steep, rugged roads with hairpin turns and can even be impassable during certain times of the year. It can be a difficult, slow trek but one that is certainly worth the effort in the end.

Today, we’re going to check out one of Arizona’s highest roads: State Route 366.

State Route 366 is also known as Swift Trail and is one beautiful drive through one of Arizona’s highest mountains, the Pinaleño Mountains and up towards Mount Graham.

The views along the road are simply beautiful. There are occasional pull-offs where you can safely stop for a few minutes to admire the landscape and turn-offs will take you to campgrounds and recreation areas.

Most of the road is paved but, shortly past the Shannon Campground, the road turns into a rougher dirt road and it closes in the winter months.

Traveling on Arizona’s mountain roads can be dangerous! Driving a 4-wheel drive vehicle is highly recommended and we suggest you check in advance for weather conditions and road closures. Remember that a portion of State Route 366 is closed in the winter from November 15 to April 15.

State Route 366 was closed earlier this year due to a forest fire but most of the road has re-opened. You can find details about the road and any closures by visiting the U.S. Forest Service website.
