It only takes about five hours to get from San Diego to Las Vegas because the quickest route is entirely on interstate highways. With I-15 and I-215, you’ll be able to make your way from one city to the next in no time (as long as there are no hold ups with traffic). The route brushes the outskirts of Los Angeles, but for the most part, it’s a direct shot between the two cities requiring minimal contact with other cities along the way.
If you prefer a more scenic route, consider getting off of I-15 near Barstow and follow I-40 to the southern entrance of Mojave National Preserve. From there, follow roads through the preserve until you connect again with I-15. This route adds about 40 more miles and takes about six hours to drive.
