Landscape Arch is the longest of the many natural rock arches located in the Arches National Park in Utah, United States. The arch is among many in the area known as Devil's Garden in the north area of the park. It was named by Frank Beckwith, leader of the Arches National Monument Scientific Expedition, who explored the area in the winter of 1933–1934, and can be reached by a walk of 0.8 mi (1.3 km) one-way along a graded gravel trail.
The Natural Arch and Bridge Society (NABS) now considers the Landscape Arch to be the fifth longest natural arch in the world, having measured the span in 2004 at 290.1 feet (88.4 m) ±0.8 feet (0.24 m), which is slightly longer than a measurement made by the Society in 2006 of Kolob Arch in Zion National Park. The most recent recorded rockfall events occurred in the 1990s when one large slab fell (1991) and then two additional large rockfalls occurred (1995). Due to the rockfalls, the trail beneath the arch was closed.
