The North Rim of the Grand Canyon is much less visited than the South Rim. This is Toroweap at the end of a very difficult 62 mile dirt road. It is a very insecure place if you are afraid of heights. That is the Colorado River, 3000 feet or so down the cliffs. There are no guardrails or rangers here to warn you about keeping away from the edges, but the height does a good job of policing itself.
