Double Arch, located in Utah's Arches National Park, is a stunning formation of natural rock arches. It is known for having the tallest opening and second longest span in the park, with an impressive height of 104 feet and a span of 45 meters. Double Arch was formed through water erosion, creating quite an impressive view to explore. Part of the charm of Double Arch is that there are no guardrails or fences to prevent visitors from exploring through the space beneath and around the arches. Even more excitingly, the arches were featured in the opening scene of Indiana Jones and the Last Crusade!
