Zion is home to 78 species of mammals, 291 bird species, 37 reptile and amphibian species, and numerous fish species. Notable mammals include desert bighorn sheep, mule deer, mountain lions, and ringtail cats. The park's diverse bird population includes the endangered California condor, peregrine falcons, and golden eagles. Reptiles such as the desert tortoise and various lizard species thrive in the arid environment. The Virgin River supports several native fish species, including the endangered Virgin River chub and woundfin.
The park supports over 900 native plant species adapted to its diverse elevation zones and microclimates. The riparian areas along the Virgin River feature cottonwood trees, willows, and ash. Higher elevations host pine-oak woodlands and Douglas fir forests. The desert areas showcase distinctive vegetation including yucca, cacti, and desert wildflowers. Spring brings vibrant wildflower displays, particularly in April and May. Notable species include the hanging gardens with unique moisture-loving plants, the rare Zion shooting star, and various endemic species found nowhere else in the world.
Zion's dramatic landscape was shaped over 250 million years through a process of sedimentation, uplift, and erosion. The park's iconic red cliffs are primarily composed of Navajo Sandstone, formed from ancient sand dunes during the Jurassic period. The Virgin River has carved the magnificent Zion Canyon, exposing nine distinct rock layers that represent different geological periods. The canyon reaches depths of up to 2,000 feet and continues to be shaped by erosion. Unique geological features include slot canyons, natural arches, and massive sandstone monoliths like Angels Landing and the Great White Throne.
Native Americans, including the Ancestral Puebloans and Southern Paiute, inhabited this region for approximately 8,000 years before European settlement. Mormon pioneers arrived in the 1860s and named the area Zion, meaning 'place of refuge.' The park was established as Mukuntuweap National Monument in 1909 by President William Taft, and was renamed Zion National Park in 1919. The Zion-Mount Carmel Highway and Tunnel, completed in 1930, marked a significant engineering achievement that opened the park to increased tourism. The Civilian Conservation Corps developed many of the park's trails and facilities during the 1930s, establishing much of the infrastructure still in use today.
The park's most iconic attractions include Angels Landing, a challenging 5.4-mile trail offering panoramic views from its 1,488-foot summit; the Narrows, a spectacular gorge where hikers wade through the Virgin River between towering canyon walls; and the Emerald Pools Trail, featuring three tiers of spring-fed pools and waterfalls. The Zion-Mount Carmel Tunnel, cut through solid rock, connects the main canyon to the east side of the park. Kolob Canyons in the park's northwest section offers a less-crowded alternative with stunning finger canyons and crimson cliffs. The Court of the Patriarchs, Weeping Rock, and the Temple of Sinawava are other must-see landmarks within the park.
Zion National Park experiences distinct seasonal variations with hot summers and mild winters. Summer temperatures often exceed 95°F (35°C) in the canyon, while winter days average 50-60°F (10-15°C) with occasional freezing temperatures at night. Spring and fall offer the most pleasant conditions for hiking. The park receives approximately 15 inches of annual rainfall, with August being the wettest month due to monsoon storms. Flash floods are common during rainy periods, particularly in narrow canyons. Winter occasionally brings light snow to higher elevations, creating stunning scenic contrasts against the red rock formations.
