Laguna Beach to Blanding: Epic Desert Road Trip Guide

The drive from Laguna Beach, California to Blanding, Utah covers approximately 650 miles and takes about 10-11 hours of pure driving time, but you will want to stretch it across multiple days. This route traverses the Mojave Desert, crosses the Colorado River, and climbs onto the Colorado Plateau, offering a dramatic transition from palm-fringed beaches to ancient red rock canyons. One little-known fact: the highway you will take through the Mojave—Interstate 15—passes within 10 miles of the San Andreas Fault at Cajon Pass, a tectonic boundary that shaped the region.
