Beyond Timpanogos Cave, Highway 92 continues up American Fork Canyon before branching off to climb behind Mount Timpanogos itself. Designated the Alpine Loop Scenic Byway, this twisting road presents stunning scenery before dropping into Provo Canyon to the south. The 9-mile Timpooneke Trail and the 8-mile Aspen Trail, both off the byway, reach the summit of Mount Timpanogos. Closed in winter, the Alpine Loop isn't recommended for motor homes and trucks pulling trailers. This is the roundabout way to get to scenic Provo Canyon from I–15; the more direct route is U.S. 189 east from Orem.
