Las Vegas to Kanarraville: Desert to Canyons Road Trip Guide

Entering Utah along I-15 after crossing the Virgin River near the Arizona border, you leave behind the Mojave Desert's creosote bushes and Joshua trees for the Colorado Plateau's towering red cliffs. The transition is abrupt—within 15 minutes of leaving Las Vegas, the elevation climbs past Mesquite, and the landscape shifts to sagebrush and juniper. This 200-mile drive, which takes approximately 3 hours without stops, has been a travel corridor for centuries; the Old Spanish Trail passed nearby, connecting Santa Fe to Los Angeles. Today, the route is a gateway to Utah's national parks, yet many drivers speed through without appreciating the geological story written in the rock layers.
