Storms can arise quickly. If there's lightning, take cover - in a building, in your vehicle, or in a cliff dwelling if you're on the trail. Stay away from metal handrails.
Pace yourself. The Island Trail descends 185 feet (240 stairs) into the canyon. You will have to climb back up. The trail is steep and there are sharp dropoffs.
This is dry country. Fill your water bottle at the visitor center, and carry it with you. Keep extra water in your vehicle.
Speed limits are reduced for the protection of pedestrians and wildlife. Please watch for both.

Walnut Canyon has been protected since 1904, first as part of the San Francisco Mountain Reserve (later Coconino National Forest). Early caretakers lived in a log cabin on the canyon rim. Walnut Canyon National Monument was established in 1915, one year before the National Park Service.
