America's most visited national park is also one of the best for fall colors as its home to a variety of trees, including tulip poplar, birch, black cherry, dogwood, sourwood, shining sumac, hickories, oaks and maples which work in concert to produce mesmerizing autumn colors across two states. This year, the experts are predicting that leaves at higher elevations of the park will begin to show off vibrant red, yellow and orange hues around mid-October, with the colors moving into lower elevations through mid-November.
