About 6mi. R/T if you don't have a high clearance 4WD. Most of the trail is via a wash that is fairly level and pleasant, the last section is up some slickrock to the top of the ridge. All-in-all not too difficult. But OMG is it worth it once you get to the top! One of the most striking vistas you will ever see. Read about the geology before you go, you'll appreciate it all the more, very rare formation with 200mi. views on a clear day. Take plenty of water.
The trailhead is like 40 miles from the nearest anything, and that anything is not much. Suggest early in the day or late in the afternoon. We did it at both times and it was like two completely different hikes. The long section in the wash can easily be maneuvered in the twilight but once it gets dark - it gets very,very dark unless the moon is out. No ambient light at all - total dark sky area and if you hang out until about an hour after sunset on a clear night you will be rewarded with a second magnificent view. It's like you can reach out and touch the Milky Way. Just take your time getting out of there - the roads are challenging. read more
