Swift Trail Parkway (SR-366)
Arizona State Route 366, the Swift Trail Parkway, climbs 28 miles from the Gila Valley floor near Safford (3,200 feet) to near the summit of Mount Graham (10,717 feet) — a gain of over 7,500 feet in one road. The highway connects with US-191 south of Safford and ascends through five distinct life zones from desert scrub to spruce-fir forest. At Turkey Flat, five consecutive hairpin turns are the road's signature feature. SR-366 is closed above Riggs Flat Lake each winter by ADOT due to snow. This sky-island climb in the Pinaleño Mountains delivers one of the largest single-road elevation gains in the American Southwest and is far less traveled than comparable Arizona climbs.
