Geology Tour Road

Mostly washboard until the one way loop. Lots of rocks in the loop with some narrow and angled roads. Some large sharp rocks. While this trail is listed as “easy”, respect the loop or you’ll tear a sidewalk. I saw a Rubicon fly past me in the rocky loop while I was in a turnoff taking in the view (it was going at least 20mph) and when I got to the end of the loop, it was parked on the side with a huge gash on the driver front wheel sidewall. Don’t bring the wrong tires (this guy didn’t, definitely not AT tires), have a spare (this guy didn’t), and don’t think you’re invincible just because you have a 4x4. You’re driving in the desert—prepare accordingly.

The two-way portion is a wide, graded road. There’s a lot of washboards in this section, but not too bad. The one-way, loop portion of the trail becomes a little rougher and more narrow. The trail is still very easy to navigate without 4x4. Any vehicle with decent clearance could manage this. The section that runs west is pretty rocky, but still not too bad. For reference, I did this with my tires at 40psi without any issues. Probably would have been more pleasant if I had aired down, but I had a lot of road driving to do later. Overall, this is a scenic and fun trail to check out.

Might be worth it to air down just because of the washboard. Trail is easy and doable for most vehicles with some clearance. Gets rougher and narrower in the 1 way loop section. There's minimal risk of pinstripes unless you have a large vehicle through the loop section.

For my first real off-road experience this was awesome! I could see a family driving this trail and camping for the night at the many campsites along the way.
