Kolob Arch is a natural arch in Zion National Park, Utah, United States. According to the Natural Arch and Bridge Society (NABS), it is the sixth-longest natural arch in the world. In 2006, the Society measured the span at 287.4 ± 2 feet (87.6 m), which is slightly shorter than Landscape Arch in Arches National Park. Differences in measuring technique or definitions could produce slightly different results and change this ranking.

Access

Kolob Arch can be reached via one of two hiking trails, either of which is approximately seven miles (11 km) long and results in a round trip of fourteen miles (23 km). The arch can also be reached from Ice Box Canyon, a canyoneering route in this section of Zion National Park. The arch is high above the ground and close to a cliffside that it frames.
