San Diego to Las Vegas Travel Guide

Hop on a direct flight from San Diego to Vegas for a break from the beach. The bright lights of the Strip beckon, but you'll soon discover a wealth of hidden gems in the city and just beyond the city limits. With a short flight, you can explore beautiful deserts, dine at world-class restaurants, take in amazing shows and win big in your favorite casinos.

Vegas has quite the reputation of wild nights and expensive entertainment, but you might be surprised to find out just how diverse and affordable the city can be. While you won't find the beautiful beach views like you're used to in San Diego, the Las Vegas area offers plenty of desert beauty just outside the city. Head to Red Rock Canyon for hikes and mountain biking of various difficulty levels. The Hoover Dam and Lake Mead give you additional natural views you won't find in San Diego. Back in town, be prepared for lots of walking. It may look like a short walk from casino to casino, but the trek on foot is actually quite far. The Las Vegas Monorail is an easy way to take a break from walking. You can also find trams between some locations or walk through air-conditioned casinos to reach other parts of the Strip. When you need a break from the Strip, head to Fremont Street, another popular area.

Las Vegas offers a lot more than the bright lights of the Strip. Explore all the city has to offer, starting with cheap flights from San Diego using our smart engine.
