Kaibab Plateau

The road to the summit, located within the Kaibab National Forest, is gravel and rocky. It’s called Forest Road 270. It’s impassable in winters. Avoid driving in this area if unpaved mountain roads aren't your strong point. 4x4 recommended. Stay away if you're scared of heights. Expect a trail pretty steep.
