Utah's oldest and *most visited national park, Zion National Park is located in southwestern Utah. Most of the park's 147,000 acres are located within Washington County; however, the extreme eastern section of the park is in Kane County, while the park's northern tip extends into Iron County. Zion Canyon is located on the southern part of the Markagunt Plateau. It is cut by tributaries of the Virgin River which have left eroded canyon walls and monoliths that are beautiful and overpowering.
Zion Canyon presents a diverse collection of nature's wonders that include such features as the towering and magnificent 2,200-foot Great White Throne, the park's most famous landmark; the Court of the Patriarchs; the Sentinel; the Watchman; Checkerboard Mesa; Kolob Arch, at 310 feet the world's largest known natural span; and the Narrows of the Virgin River, where a person can walk upstream to places so narrow that both sides of the canyon walls can almost be touched with one's outstretched hands.
