Tours from Los Angeles to Las Vegas cross the Mojave Desert on Interstate 15, then continue east to the Grand Canyon, Antelope Canyon, Horseshoe Bend, Zion or Bryce Canyon. Some end in Las Vegas and others loop back to Los Angeles, with hotels, coach transport and a guide included.
Las Vegas is about 430 km from Los Angeles, roughly four to five hours on Interstate 15 across the Mojave Desert, longer on Friday and Sunday when traffic is heavy. Tours often break the drive with a stop on the way and then continue east from Las Vegas to the Grand Canyon, Zion or Antelope Canyon, which is why most routes run over several days.
Driving yourself is flexible but means long desert stretches, parking at busy viewpoints and arranging hotels and park entry on your own. A guided tour handles the driving, hotels and timing between parks, and gets you into places like Antelope Canyon, which requires a Navajo guide. It suits travelers who want to see several parks in one trip without planning each leg.
Spring and fall are the most comfortable, with mild desert days and clear views at the Grand Canyon. Summer is peak season but very hot, often above 40 C in Las Vegas and the desert. Winter is mild in Las Vegas and quieter overall, though the Grand Canyon South Rim and Bryce Canyon can have snow, so pack a warm layer.
