We need your help. Immediately after the 1991 rockfall event, the National Park Service closed the trail which took visitors up and under the arch. The trail under the arch remains closed today. It is a dilemma! The longer time passes without a rockfall, the more stable the formation may seem. On the other hand the passage of time takes Landscape Arch closer to ultimate collapse. So, in the interest of visitor safety and preservation of the landscape beneath this fabulous arch, the longer trail under the arch remains closed. Please respect this closure by staying on designated trails.
