Tuba Arch is north of Flagstaff Arizona near the town of Tuba City.
Take Rt. 89 north from Flagstaff and turn right onto Rt. 160 for 7.2 miles
to Navajo Rt. 6731 on the right. Drive down Rt. 6731 and park after
crossing a bridge over a wash. Look for a small volcanic dike and hike
south on the east side of it for about 0.3 miles to the arch. The arch has a
span of 15 ft. and height of 25 ft.
