The sultry red rock landscapes of Arches National Park are among the most dramatic in the country. Flamboyant geological formations cast stunning silhouettes against brilliant skies, making this one of the most photographed national parks in the United States. The park boasts over 2000 stone arches, including the world-renowned Delicate Arch, a favorite spot for gazing at the sunset, and the 306 foot long Landscape Arch, one of the longest arch formations in the world.
