Alpine Loop Scenic Byway
Twenty hairpin miles over the shoulder of Mount Timpanogos — UT-92 from American Fork Canyon into Provo Canyon, past Timpanogos Cave, Cascade Springs, and Sundance. Paved and narrow, closed in winter, unbeatable in fall.
The Alpine Loop is the shortest drive in this guide and, mile for mile, maybe the most scenic — twenty paved miles of hairpins that climb over the shoulder of Mount Timpanogos, the 11,752-foot peak that walls off the east side of Utah Valley. UT-92 leaves American Fork Canyon, tops out near 8,000 feet, and drops into Provo Canyon, trading limestone cliffs for aspen and fir the whole way. It is gloriously short on services and long on views, and in late September the canyon maples turn the loop red and gold.
From the American Fork side, the first stop is the obvious one: Timpanogos Cave National Monument, three decorated limestone caverns reached by a steep mile-and-a-half trail up the canyon wall. From there UT-92 climbs in earnest to the Alpine Loop Summit, where the trees open onto the full glacier-carved face of Timpanogos. A paved spur drops east off the top to Cascade Springs, where seven million gallons a day well up through travertine terraces and clear pools, looped by an easy boardwalk — the gentlest stop on a road full of steep ones.
Over the summit the road bends down the Provo Canyon side. Aspen Grove sits at the foot of Timpanogos, the trailhead for both the long summit hike and the much shorter walk to Stewart Falls, with a historic stone amphitheater tucked into the pines. A few miles below is Sundance Mountain Resort, Robert Redford's small, deliberately understated ski-and-arts hideaway on the mountain's lower slopes — a fine place to stop for lunch whether or not there is snow.
The loop ends where UT-92 meets US-189 in Provo Canyon, just above Bridal Veil Falls, a 600-foot double cascade that pours straight down the canyon wall. A few practical notes: the road is narrow and full of hairpins, closed to vehicles over thirty feet and to everyone once the snow flies — count on roughly late May through late October. Stopping at the trailheads and springs requires a Forest Service recreation pass, sold at the canyon fee stations. Drive it slowly; this is a road built for photo stops, not mileage.
