Laguna Beach to Tropic: A Desert Road Trip Guide

The route from Laguna Beach, CA, to Tropic, UT, spans 480 miles of profound geological and cultural transition, a journey from the Pacific's coastal mist to the high desert's crimson cliffs. The drive typically takes 7.5 to 10 hours via Interstate 15 north to Utah State Route 20, cutting east on US-89, then winding through the red rock of Utah State Route 12. A little-known fact: the final 20 miles into Tropic descend 2,000 feet in elevation along a winding canyon road that once served as a Paiute trade route.
