  • We have driven this loop drive twice and it is very interesting. You can see the geology and uplift in the rock formations - some look like the remains of huge dinosaurs. No matter what time of year, ...  more »
  • Very nice track 8 miles north of Barstow on a loop of 5 miles to discover the Mojave desert, with rocks of many beautiful colors. Perfectly accessible with a car (not 4 x 4) sedan in the summer because the track is dry, if you roll gently.

  • Beautiful place. Love the colors and formations. Geology is wonderful. Enjoyed the scenic drives as the valley walls get closer and closer as your car wanders through the basin. The road Is nicely graded that goes through a wash. Very epic, scenic panoramic views. Highly recommend spring, fall or winter times to visit as it can get hot!! We went in February, Not too far of a drive from Barstow or on the dirt road. We also hiked among the Mojave desert vegetation and enjoyed the Joshua trees. Think we got a glimpse of the lakebed with Goldstone. Great picture taking opportunities!
  • One of the best desert day trips in so.cal. lot's to see & do in the park and serrounding area's. I have been to this park dozens of times and brought many friends to Rainbow basin and owl canyon. I highly recommend a trip here.
  • Amazing landscape.
  • Amazing geology here. The classic photo of a syncline, found in multiple geology texts was taken here. Truly amazing by moonlight. Nearby Owl Canyon has an entire chapter of GEOLOGY UNDERFOOT IN SOUTHERN CALIFORNIA, guiding the hiker through various rock formations. Camping is available at Owl Canyon.
  • A gem in the Southern California area of the Mojave desert
