An RV journey through these magnificent landscapes ensures your holiday is comfortable and safe, giving you a climate-controlled retreat after a long day of exploration.

By letting a professional route planner handle the logistics, your motorhome getaway becomes a relaxing and memorable experience. An RV road trip effortlessly connects the high plains of Wyoming with the deep canyons of Utah and Arizona.

If you are flying into Colorado to start your journey, securing your vehicle is simple. You can easily rent a camper in Denver to begin your scenic drive before pointing the compass north and eventually dropping your rig off in Las Vegas.

Itinerary Summary at a Glance

The High Plains and the Black Hills

The ascent from the urban energy of Denver into the history-rich plains of Wyoming and the Black Hills of South Dakota offers a spectacular beginning to your journey. Your grand adventure ignites as you grab some sweet road trip treats at Hammond’s Candies in Denver before driving your motorhome north. Crossing into Wyoming, you will dive into frontier history at the Nelson Museum of the West and stretch your legs among the serene flora of the Cheyenne Botanic Gardens.

Because you are traveling in a campervan, you will appreciate the massive parking structures designed specifically for oversized vehicles here. Renting cruisers from Rabbit Bicycle & Repair to ride the Mickelson Trail and donning a hard hat to explore the Broken Boot Gold Mine in Deadwood provides a thrilling end to your Black Hills chapter.

Buffalo Jumps, Towers, and Cowboy Towns

The journey back across the Wyoming border is a deep dive into Native American heritage and Wild West legends. You will witness the fascinating archaeological site at the Vore Buffalo Jump Foundation before marveling at the towering monolithic columns of the Devils Tower Visitor Center. To drive comfortably and leisurely, the wide, sweeping roads of northeastern Wyoming are an absolute joy for an RV.

As you head west, stepping back in time at the Frontier Relics & Auto Museum and touring the historic Mountain Meadow Wool Mill offers a fascinating look at regional industry.

Entering the world's first national park is an unforgettable experience. Driving your motorhome into Yellowstone, you will scan for bison and wolves at the Yellowstone River Overlook at Hayden Valley and descend the metal stairs of Uncle Tom's Trail to view the Lower Falls. The geothermal wonders begin at the Norris Geyser Basin Museum and continue past the Gibbon Falls Wildlife Trail.

Because parking a campervan in Yellowstone requires strategy, arriving early at the Grand Prismatic Spring Parking Lot or the Fairy Falls Trail Parking Lot is essential to see the vibrant colors without the crowds. Watching the reliable eruption at the Old Faithful Visitor and Education Center is an absolute must. Driving south into Grand Teton National Park, you will hike the serene shores from the String Lake Trailhead and take to the water with Jenny Lake Boating. Before leaving the valley, admiring world-class art at the National Museum of Wildlife Art in Jackson offers a refined cultural stop for an RV family.

Idaho Caves, Bear Lake, and the Salt Lake Valley

The transition from the Tetons through Idaho and into Utah blends subterranean wonders, bright blue lakes, and pioneer history. Crossing the border, you will navigate the cool, stalactite-filled chambers of Minnetonka Cave and relax on the sandy shores of North Beach State Park at Bear Lake.

Your motorhome route then glides south into the Salt Lake Valley. Stepping into the 19th century at This Is The Place Heritage Park and visiting the diverse animal habitats at the Hogle Zoo provides brilliant fun for the camper traveler. The highways around Salt Lake City are wide and well-maintained, making urban navigation surprisingly easy for an oversized vehicle.

Red Rocks, Hoodoos, and Navajo Slot Canyons

Southern Utah and Northern Arizona are a masterclass in sedimentary geology and ancient cultures. Heading south, you will explore ancient petroglyphs at the Fremont Indian State Park and Museum and tackle the ropes and ziplines at Big Rock Adventure. The landscape dramatically shifts as you arrive at the Bryce Canyon National Park Visitor Center. Leaving your RV parked and saddling up for a ride through the hoodoos with Ruby's Horseback Adventures is an incredible way to experience the canyon.

Crossing into Arizona, you will base your campervan in Page. Since you cannot drive into the slot canyons, joining guided excursions like Antelope Canyon Tours - by Carolene Ekis or exploring the flooded canyon walls with Antelope Canyon Boat Tours is mandatory. Finally, a short hike to the sheer cliffs overlooking Horseshoe Bend will leave your motorhome crew breathless.

Grabbing a classic milkshake at Mr D'z Route 66 Diner and browsing the vintage memorabilia at the Arizona Route 66 Museum offers a nostalgic afternoon for an RV family. Pushing toward Nevada, you will marvel at the engineering of the Hoover Dam Parking Garage and Visitors Center (be prepared for a brief security inspection of your motorhome). The grand finale brings you into Las Vegas. After snagging deals at the Las Vegas North Premium Outlets, you will walk the dazzling Las Vegas Strip and watch the iconic fountains dance at the Bellagio Hotel and Casino.
