Double Arch

Overview

Double Arch is the showstopper of the Windows Section: two colossal sandstone spans sharing the same base, forming a natural amphitheater that swallows you whole. You can see it from the parking lot, but it’s worth the quick stroll to stand beneath the arches and feel the scale.

Why it’s unique

Most arches here eroded from the side; Double Arch is a pothole arch carved from above by water. The larger opening stretches roughly 144–148 feet across and rises about 104–112 feet—tallest opening and second-longest span in the park. It even snagged a cameo in the opening of Indiana Jones and the Last Crusade.

Trail & access

From the Double Arch parking area at the end of Windows Road, it’s an easy 0.5–0.6 mile round trip with about 30 feet of gentle elevation. No guardrails or fences—feel free to wander right under the spans. If the main lot is full, use the nearby Windows lot and take the short connector path.

What it feels like

Under the twin arches, you get shade, echoing acoustics, and huge photo angles. Many visitors scramble partway up the slickrock for perspective; just know that downclimbing can be trickier than going up.

Geology snapshot

Double Arch began as two potholes on top of the rock. Over time, water enlarged them and eroded the rock between, leaving today’s striking twin-span cathedral.

Facilities

Adjacent parking for cars and larger vehicles, plus vault/composting toilets at the lot. No food, water fill, or stores—bring what you need.

Safety notes

Rock scrambling here is enticing but hazardous; wear grippy shoes and watch your footing. Summer heat is real—carry water and sun protection.

Wildlife

The Windows Section commonly hosts lizards, birds, and small mammals—keep your eyes on the warm rocks and shrubs.

Best time to visit

Arrive early or late to beat crowds and snag parking. Early light is soft and quiet; sunset can be gorgeous in the amphitheater glow. During seasons with a timed-entry system, secure a reservation before you go.
