Arches National Park is a unique place in the world - nowhere else has as many and as varied natural arches. These arches are formed by the weathering of sandstone layers, primarily the Entrada Sandstone. This sandstone rests on a thick layer of salt, which came from an ancient sea about 300 million years ago. The salt is unstable and can move, change, and dissolve under pressure, causing cracks and faults in the rock above. Water, ice, and wind then get into these cracks and wear away the rock, creating holes and gaps that eventually become arches.
There are over 2,000 natural rock arches in the park, with spans from 3 to 306 feet. Landscape Arch is the longest arch in the park with a span of 306 feet, and Double Arch has the tallest opening at 112 feet. The arches are still forming and changing, as some of them fall and new ones appear.
Arches National Park has a long human history. This land was home to various indigenous cultures, including the Ancestral Puebloans and the Fremont people. You can see pictographs and petroglyphs left behind on various trails in the park. Today, several Native American tribes consider Arches National Park to be part of their ancestral homeland. You can visit Wolfe Ranch cabin to see evidence of early European-American settlers in the area.
Keep an eye out for mule deer, desert bighorn sheep, coyotes, foxes, rabbits, lizards, snakes, and many birds, including peregrine falcons. The park also has over 450 species of plants, some of which are rare or endemic to the region.
Arches National Park is divided into several sections, including the Entrance area, Courthouse Towers, the Windows Section, and Devils Garden. The 18-mile scenic drive that winds through the park offers access to viewpoints and trailheads for short strolls and strenuous hikes.
Arches National Park is particularly stunning at sunrise and sunset, when the red rocks and shadows create dramatic views, and is a designated International Dark Sky Park. Arches is very popular, so plan for timed entry reservations during peak season and potentially crowded trails.
