Embarking on a 1,706 mi journey from the sun-soaked coast of Southern California to the rugged frontiers of Montana is the quintessential American road trip. RV travel is uniquely suited for this expedition because it allows you to transition seamlessly through drastically different environments—from coastal breezes and expansive deserts to high-altitude red rock canyons and wild northern plains. Instead of rushing between hotel check-ins, an RV lets you embrace slow travel, waking up to a desert sunrise one morning and falling asleep under the towering hoodoos of Utah a few days later.
This expedition is best enjoyed by breaking the drive into distinct regional stages. Rather than a rigid daily schedule, think of your journey in these broader rhythms. For the full, detailed day-by-day itinerary, be sure to check the complete plan on RV PLANET.
This 1,706 mi route is packed with diverse experiences. Here is a look at the types of attractions you will encounter along the way.
History comes alive right from the start. In San Diego, you can explore the USS Midway Museum, stepping aboard a floating naval legend to delve into America's maritime past. Later in the journey, the Pioneer Saloon in Goodsprings, Nevada, offers a fascinating glimpse into the timeless charm and rugged history of the Wild West.
For families, this route delivers unforgettable magic. A major highlight in California is Disneyland Park, where visitors of all ages can experience world-class amusement park enchantment. As you travel through Nevada, the Las Vegas Flamingo Wildlife Habitat provides a lush, refreshing oasis in the desert, allowing you to observe exotic wildlife in an unexpected setting. The route also features opportunities for visiting local zoos, aquariums, and botanical gardens.
The transition into Utah is a paradise for outdoor enthusiasts. You can get your adrenaline pumping with Zion Cycles, exploring the captivating landscapes of Zion National Park on two wheels. Further along, the enchanting world of Bryce Canyon National Park awaits, offering breathtaking sunsets and famous hoodoos. Throughout the route, you'll find ample opportunities for hiking, kayaking, horseback riding, and exploring natural caves.
We recommend dedicating a full 14 days to this 1,706 mi journey. This two-week timeframe allows you to average a comfortable driving distance while leaving plenty of time for full-day excursions at theme parks, national parks, and historical sites.
Absolutely. Few routes offer such a profound cross-section of the American West. The sheer variety of biomes—beaches, deserts, canyons, and northern plains—makes this an incredibly rewarding expedition for travelers who want to see how the landscape changes across six different states.
This itinerary is highly versatile. The mix of amusement parks, wildlife habitats, and interactive museums makes it perfect for families. Meanwhile, the stunning hiking areas, scenic routes, and cycling opportunities in places like Zion and Bryce Canyon make it equally thrilling for couples and outdoor adventurers.
Late spring (May to June) and early fall (September to October) are ideal. Summer is fantastic for the northern states (Idaho, Wyoming, Montana) but can be intensely hot in the Mojave Desert and Southern Utah. Winter travel is not recommended due to heavy snow and road closures in the northern Rockies and high-elevation Utah parks.
Planning a 1,706 mi one-way trip requires a bit of logistical foresight. Because you are picking up in San Diego and dropping off in Billings, you will need an RV rental that permits one-way travel. Be aware that one-way rentals typically incur a drop fee to cover the cost of returning the vehicle. Additionally, ensure your rental package includes sufficient mileage to cover the 1,706 mi distance, plus any side trips to campgrounds or trailheads.
When budgeting for accommodations, expect a mix of premium private RV resorts (especially near Anaheim and Las Vegas) and more nature-focused state or national park campgrounds in Utah and Montana. For specific one-way fees, mileage package costs, and live vehicle availability, check the search tools on rvplan.net.
