Morning Glory Natural Bridge

Grandstaff Canyon Trail is one of the finest half-day hikes in the Moab area. The trail follows a perennial stream through a narrow canyon carved into Navajo Sandstone, passing through a lush riparian oasis of cottonwood trees and willows, a striking contrast to the surrounding desert. The destination, Morning Glory Natural Bridge, spans 243 feet, making it the sixth longest natural rock span in the United States. The hike involves multiple stream crossings (8-11 depending on conditions), and the final approach to the bridge includes a steep climb into a side canyon. The shaded canyon makes this hike more tolerable than exposed desert trails during warm months. Note: poison ivy grows along sections of the trail, particularly near the pool at the base of the bridge.

From downtown Moab, drive north on US-191 approximately 1 mile, then turn right onto UT-128 (River Road). Continue about 3 miles along Hwy 128. The signed Grandstaff Canyon Trailhead is on the right side of the road with a paved parking area, vault toilet, and information kiosk.

From the trailhead, cross a short bridge and follow the trail into the canyon along the stream. The path proceeds upstream for about 1.5 miles, crossing the stream multiple times. Waterproof footwear is recommended, especially in spring. At approximately 1.5 miles, the canyon forks. Take the second side canyon on the right and ascend a steep slope for about 0.5 miles to reach Morning Glory Natural Bridge, which frames a large alcove with a seasonal pool. Return the same way.
