White Mountains of New Hampshire are a range in the northern part of Appalachian Mountains. They are sometimes called the Presidential Range, because many of the peaks are named for United States presidents. The highest is Mount Washington (1,917 m/6,288 ft), a very popular destination thanks to the road to the summit opened in 1861. The auto road, 12 km/8 miles long rises from the base at elevation 477 m/1,565 ft giving travelers in automobiles 1,439 m/4,723 ft vertical difference in elevation in about 15 minutes.
