For a beautiful summer drive where you’ll find blissful pockets of outdoor beauty, head for this 20-mile byway south of Salt Lake City. The winding mountain road, which circumnavigates 11,750-foot Mount Timpanogos, offers access to miles and miles of day-hiking trails. The route, also called Highway 92, passes Timpanogos Cave National Monument (worth a stop for a ranger-led underground tour). Other recommended detours include Robert Redford’s Sundance Mountain Resort, and turnoff that leads to a quarter-mile boardwalk hike to Cascade Springs. The loop is open from Memorial Day until the first snow of fall.
