Some of the most popular areas in the park, including Arches Scenic Drive, Delicate Arch Viewpoint, and the Windows Trail, are open 24 hours a day, allowing you to experience the beauty of the park even after sunset.
During peak tourist seasons (March to October), the park may extend its hours to accommodate increased visitation, and some campgrounds and facilities might have different operating schedules.
Always plan ahead and arrive with enough time to explore the park before closing time to ensure you have a fulfilling experience.
