A view of the highway in East Canyon during the fall when the colorful red and orange leaves on the maple and scrub oak are at their peak. East Canyon runs northeast of Parley’s Canyon, through which Interstate 80 (I-80) runs on its way to Wyoming. The closest cities to this spot are Park City, and Heber, with Salt Lake City to the west down in valley below the Wasatch Mountains. The best time to see these colors are September. Utah.
