Sand Dune Arch, Natural arch in Arches National Park, Utah, US
Sand Dune Arch is a natural rock formation in Arches National Park, Utah. It stands between tall red sandstone walls with a sandy floor, accessed by walking through narrow canyon passages that wind between the surrounding stone.
This formation developed over millions of years as water and wind eroded the layered sandstone. The continued wear on softer rock sections eventually opened the passage that defines the arch today.
Native American tribes of the region incorporated the arch and surrounding landscape into their traditional stories and used the area for ceremonial gatherings.
The hike is short and straightforward, taking about 30 minutes round trip over sandy ground. Bring plenty of water and wear appropriate footwear, as the sand heats up in warm weather and you walk through narrow rocky passages.
The area beneath the arch forms a natural sandbox where sand remains cool due to the shade cast by high rock walls. These shaded pockets provide welcome relief during hot days.
