Why Zion National Park
Zion National Park is situated in southwestern Utah adjacent to the town of Springdale. Encompassing 229 square miles across Washington, Iron, and Kane counties, the reserve lies at the intersection of the Colorado Plateau, Great Basin, and Mojave Desert. Its terrain exhibits dramatic vertical variation, extending from an elevation of 3,666 feet at Coalpits Wash to 8,726 feet at Horse Ranch Mountain. This landscape contains mountains, red sandstone canyons, buttes, mesas, monoliths, rivers, and natural arches. Supported by four ecological life zones—desert, riparian, woodland, and coniferous forest—the park hosts diverse plant species alongside 289 bird species, 75 mammal species, and 32 reptile species.
The centerpiece of the park is Zion Canyon, a 15-mile-long gorge measuring up to 2,640 feet deep. Carved by the North Fork of the Virgin River, the canyon is framed by reddish and tan Navajo Sandstone walls. The Virgin River features one of the steepest stream gradients in North America, falling 50 to 80 feet per mile. Geographic landmarks throughout the canyon include Angels Landing, The Sentinel, The Great White Throne, Checkerboard Mesa, and the Court of the Patriarchs. To the northwest, the Kolob Canyons area features Tucupit Point and Kolob Arch, while the Kolob Terrace region contains The Subway slot canyon and panoramic views from Lava Point.
Human activity in the area dates back roughly 8,000 years to early nomadic family groups. Over time, agricultural societies developed, including the Basketmaker Ancestral Puebloans, Virgin Anasazi, and Parowan Fremont cultures. Following extended droughts and flooding, these early groups departed by 1300 and were succeeded by Southern Paiute subtribes such as the Parrusits. Mormon pioneers settled the Virgin River valley in the mid-19th century, farming the canyon floor. President William Howard Taft set aside the gorge as Mukuntuweap National Monument in 1909. Congress officially established Zion National Park in 1919, later incorporating the Kolob Canyons area in 1956.
A six-mile scenic road runs through Zion Canyon, terminating at the Temple of Sinawava, where a hiking path continues to a narrow gorge called The Narrows. Between early April and late October, access along this canyon drive is provided by a free shuttle bus service. State Route 9, known as the Zion–Mount Carmel Highway, traverses the eastern side of the park through a tunnel, connecting to US 89. Zion features a cold semi-arid climate with hot summer days, mild winters, and changeable spring weather. Late summer afternoon storms often bring flash floods, while autumn foliage peaks in the canyon during late October.
