I love this trail, miller jeep trail in hungry valley, ca. I learned how to 4wd in my first 4wd vehicle 30 years ago, a 90 Jeep wrangler. Every 4wd from a hummer h2, to Jeep Cherokee, to 96 4 runner I have tested it out on the Miller Jeep trail.

The trail is challenging yet doable in most stock Jeeps and 4 runners (no crossovers). You can expect damage if you don't choose the right line or have the correct skills to get over the big rocks. I love the trail because it is a great way to test your skills and vehicle without causing major damage if you have the skills and the right SUV or Truck. These guys show the beauty and difficulty of the trail.
I would to see some of your fav 4 runner trails.
