A rugged hike through a narrow canyon rewards the hiker with a close-up view of Brimhall Natural Bridge, a double span. The route is largely unmarked, so carrying a topographic map is recommended. It is extremely hot in summer and water sources are unreliable; carry adequate water. Use caution in narrow canyons during flash flood season (July-September.)

From the Halls Creek Overlook trailhead, the total round trip distance is 4.6 miles. The hike can be done as a long day hike. Backcountry permits are required for all overnight trips and can be obtained at the visitor center.
