Rainbow Basin is just outside Barstow and offers easy access to regular passenger cars and it appears there are additional opportunities for those with more rugged vehicles and those that are hiking/camping. We spent a good 2+ hours driving and stopping and taking pictures and really enjoyed it. The colors reminded us of Artist's Palette in Death Valley. This is a good side trip in between Los Angeles and Las Vegas, especially if you're splitting the drive and spending one night in Barstow.
