The hike to Double O Arch is considered strenuous. It involves navigating the Devils Garden Primitive Loop, which includes sections of rock scrambling and narrow ledges, particularly past Landscape Arch. Hikers should be prepared for varied and challenging terrain.
The round-trip hike to Double O Arch from the Devils Garden trailhead is approximately 4.1 to 4.2 miles (6.6 to 6.8 kilometers). Depending on your pace and time spent enjoying the views, it can take 3 to 4 hours or more to complete, especially considering the challenging terrain.
Due to the strenuous nature of the trail, including rock scrambling and narrow ledges, the hike to Double O Arch is generally not recommended for very young children or those unaccustomed to challenging hikes. Families with older, experienced children who are comfortable with rugged terrain may find it rewarding.
No, pets are not allowed on any hiking trails in Arches National Park, including the trail to Double O Arch. This policy is in place to protect wildlife and ensure visitor safety. Pets are only permitted in parking lots, along roads, and in campgrounds.
To avoid the largest crowds, consider visiting during the cooler months of spring or fall, or by starting your hike very early in the morning, especially during peak season. The Primitive Loop Trail beyond Landscape Arch tends to be less crowded than the initial sections of the Devils Garden Trail.
The trail to Double O Arch, part of the Devils Garden Primitive Loop, offers access to an amazing concentration of formations. You'll pass by Landscape Arch, Navajo Arch, Partition Arch, and Pine Tree Arch. From Double O Arch itself, you can also spot Dark Angel, a prominent 150-foot sandstone pillar.
Double O Arch, like other arches in Arches National Park, was formed over millions of years through the erosion of Entrada Sandstone. This Jurassic-era rock was deposited as ancient desert dunes, then buried, uplifted, and fractured. Water, freeze-thaw cycles, and the dissolution of calcite cements gradually sculpted these fins into the arches we see today.
Given the strenuous and exposed nature of the trail, hikers should carry plenty of water (at least 2-3 liters per person), wear sturdy hiking boots with good ankle support, and bring sun protection (hat, sunscreen, sunglasses). Layers of clothing are also advisable due to temperature fluctuations.
No, despite its name, Double O Arch is not the arch featured in the opening scene of Indiana Jones and the Last Crusade. That iconic scene was filmed at the Double Arch, which is located in the Windows Section in the southern part of Arches National Park.
While impressive from any angle, many visitors and photographers agree that the most beautiful view of Double O Arch is often found by observing it from behind. This perspective can offer unique compositions and highlight its distinctive double configuration.
