Double O Arch

Overview

Double O Arch is the showstopper at the far end of the Devils Garden hike: two perfectly stacked "O" openings carved into a single sandstone fin. It’s the second‑largest arch in Devils Garden (after Landscape Arch) and one of the park’s most photogenic spots.

The Hike & Difficulty

Plan on about 4.2 miles round trip if you head straight there, or closer to 5.8 miles if you add the popular spur arches along the way. After Landscape Arch, the trail turns primitive with cairn navigation, slickrock, and a fin traverse with exposure on both sides—fun for confident hikers, intimidating if heights aren’t your thing. Expect roughly 360 feet of total gain.

What You’ll See

The route threads a maze of sandstone fins and spires with big canyon views. Short spurs visit Tunnel, Pine Tree, Partition, and Navajo Arches before you round a corner and the double “O” finally pops into view. At the arch, you can walk through the lower opening for creative perspectives.

Geology Snapshot

These arches formed in Entrada Sandstone as wind, water, and time exploited weaknesses in a tall fin. Differential erosion carved two adjacent openings stacked vertically—hence the double "O."

Wildlife

Devils Garden is classic desert habitat. Keep an eye out for lizards warming on rocks and birds flitting among the fins; small mammals make occasional cameos. Early and late in the day are your best bets for activity.

Practicalities & Safety

There’s no water, shade is limited, and there are no facilities at the arch. Restrooms are back at the Devils Garden Trailhead. Bring sturdy footwear, plenty of water, sun protection, and snacks. Trails can be slick when wet, and summer heat is no joke.

Extensions

If you’re still energized, continue past Double O to Dark Angel or commit to the Primitive Loop for a tougher, more adventurous circuit.

Best Time to Visit

Start early to beat heat and crowds and to snag trailhead parking; late afternoon also works well for softer light on the fins and the arch. Midday brings harsher light and heavier traffic, especially in peak season.
