The landscapes on this route are among the most diverse in the United States. Starting in St. George, you are surrounded by the red sandstone cliffs of Snow Canyon and the carved terrain of Zion National Park. As you drive I-15, the Virgin River Gorge presents sheer rock walls changing from deep red to gray limestone, a spectacular prelude to the Mojave Desert.

As you near Las Vegas, the desert opens into vast basins dotted with creosote and Joshua trees. The Mojave Desert's unique geology includes the Kelso Dunes and the Cinder Cones Natural Area. Further west, the Cajon Pass marks the transition to the coastal ranges, ending with the chaparral-covered hills of the Santa Monica Mountains and finally the Pacific Ocean at Venice Beach.

• Virgin River Gorge: 11-mile canyon with steep walls, managed by the Bureau of Land Management. Look for the Virgin River flowing alongside.

Fuel stations are plentiful along I-15 but become scarce in certain stretches like the Mojave Desert. Plan to refuel in St. George, Las Vegas (around 120 miles), and Barstow (another 150 miles).

Road conditions are generally good, but the I-15 through the Virgin River Gorge can have tight curves and no shoulders. In winter, snow and ice are possible near St. George and in the mountains. In summer, extreme heat in the desert can cause overheating. The California coast section on CA-1 is narrow and winding near Malibu, but smooth pavement is standard.

Public restrooms are available at most rest areas, such as the one near Mesquite, NV (milepost 120). For overnight stays, budget motels line the exits in Barstow, Victorville, and Santa Monica. RV parks are available near Las Vegas and in coastal towns.

Safety starts with your vehicle: check tire pressure, coolant, and oil before leaving St. George. The desert heat can be brutal; carry at least a gallon of water per person. In the mountains, be prepared for sudden weather changes. On CA-1 near Malibu, watch for cyclists and tight turns.

For families, the route offers many kid-friendly stops. The Las Vegas Strip, while not entirely child-oriented, has attractions like the Bellagio fountains and the Adventuredome indoor theme park. In Barstow, the Route 66 Mother Road Museum is free and educational. The Santa Monica Pier with its historic carousel and aquarium is a sure hit. For outdoor activities, Snow Canyon State Park near St. George has gentle hikes for all ages.

• Rest stops: Wheatley Rest Area (I-15 milepost 22), Barstow Station (off I-15, exit 184), Leo Carrillo State Beach (CA-1, restrooms and picnic tables).
• Fatigue management: Alternate driving between Las Vegas and Baker is a good idea. Use audio guides or podcasts to stay alert. The Mojave Desert stretch can induce highway hypnosis – take a break every 2 hours.
• Pet-friendly options: Dog-friendly stops include the Red Rock Canyon National Conservation Area (leashed dogs allowed) and the Venice Beach Boardwalk. Many motels along the route accept pets, but check ahead.

Hidden off-route spots worth the detour include the ghost town of Calico (exit 185 off I-15 near Barstow), a restored silver mining town with shops and a mystery shack. Another is the Integratron in Landers, a dome-shaped structure said to have acoustic and healing properties – requires advance booking.
