Planning a Kennewick to Las Vegas road trip is easy since there are so many great attractions to see between this city in southern Washington and the glitz and glamour of Las Vegas. Multiple attractions and points of interest in Oregon and Idaho await. Once you get to Utah, you’ll be able to travel to a string of some of the country's most beautiful and distinctive national and state parks. At the end of the road, you’ll be able to gamble and party at some of the world’s most famous casinos in Sin City.
While there are some earlier points along your Kennewick to Las Vegas road trip route at which you could go a bit off the beaten path and drive to some lovely national parks, Utah by itself provides you with some outstanding national parks that are closer to your route. The Grand Canyon is also within easy driving distance.
Capitol Reef National Park
Capitol Reef National Park is one of several Utah national parks that will give you your fill of canyons and unique rock formations. Travelers frequently visit popular attractions such as the Waterpocket Fold, Cathedral Valley, and the Hickman Bridge Arch. Whether you want to take a leisurely stroll around Capitol Gorge or hike through the challenges of Navajo Knobs, you’ll find plenty of rocks and desert terrain at Capitol Reef National Park.
Canyonlands National Park
Canyonlands National Park is quite close to Capitol Reef as well as Arches National Park. You could easily spend multiple days exploring these amazing parks. Canyonlands is aptly named as it is packed full of numerous canyons and colorful desert vistas. Within its 520 square miles, visitors can explore mesas, natural mazes, plateaus, and even original Native American rock paintings.
Bryce Canyon National Park
Next up on your road trip itinerary from Kennewick to Las Vegas is Bryce Canyon National Park. It’s located between Capitol Reef National Park and Zion National Park. This park is known for its distinctive rock formations called hoodoos, which were formed by long-term erosion and weathering. You can explore these types of formations and other iconic attractions on the more than 30 miles of trails the park offers.
Zion National Park
Zion National Park is easily one of Utah’s most stunning parks. Humans have been drawn to this area for roughly 8,000 years for a reason. One big draw to Zion is the Narrows, which is a section of Zion Canyon with walls 1,000 feet high. Visitors love hiking through the Virgin River while admiring the walls of this magnificent gorge. If you would rather hike in ponderosa forests, you can do that here as well courtesy of the challenging East Rim Trail, which features an elevation change of roughly 2,000 feet.
Grand Canyon National Park
In many respects, Grand Canyon National Park is the grandest national park in America. This road trip from Kennewick to Las Vegas goes through a small portion of Arizona, but that bit of Arizona is, fortunately, the part that houses the Grand Canyon. Every year, 6 million tourists flock to this 1.2 million-acre park to view the extremely large gorge formed by the Colorado River over many millennia. The most popular trail in the park is the Rim Trail, which gives visitors access to iconic places like Monument Creek Vista, Mather Point, and Yavapai Point Observation Station.
Hilgard Junction State Park
Hilgard Junction State Park is right off Interstate 84 in Oregon. It’s roughly two hours away from Kennewick, so it’s close to the beginning of your Kennewick to Las Vegas RV road trip. Travelers can fish and swim in the Grande Ronde River and camp and hike among the ponderosa pines and cottonwoods.
Bruneau Dunes State Park
Most travelers don’t expect to be able to explore desert environments in Idaho, but Bruneau Dunes State Park gives visitors the chance to do so. Hiking, horseback riding, stargazing, and fishing are popular here. One of the most interesting things you can do in the park, however, is sand-sledding, which involves sliding down the park's large dunes on a sandboard. Whether you’re young or simply young at heart, you’ll enjoy sledding on the sand of Bruneau Dunes State Park.
Antelope Island State Park
You can’t take a Kennewick to Las Vegas road trip without stopping by the Great Salt Lake. Antelope Island State Park covers all of Antelope Island, which is in the Great Salt Lake itself. You can explore the park’s beaches, mountains, and plains that are home to many native species. Whether you want to hike to the top of Fray Peak or swim in the Great Salt Lake, you can do all of that and more at Antelope Island State Park.
Goblin Valley State Park
Goblin Valley State Park is located between Capitol Reef National Park and Canyonlands National Park. If you want to get a preview of the hoodoos that you’ll get to see at Bryce Canyon National Park, you should check out this park. Hiking and biking are big here, but you can also stargaze thanks to the park’s dark night skies. The park also has a nine-hole disc golf course that will give you a great game with unique surroundings.
Kodachrome Basin State Park
Kodachrome Basin State Park is southeast of Bryce Canyon National Park. Sedimentary pipes, sandstone layers, and lovely desert colors are all on display here. You can explore the multiple trails in the park on foot, horseback, or a bike.
Tamastslikt Cultural Institute
Visiting the Tamastslikt Cultural Institute on the Umatilla Reservation should be one of the first items on your road trip itinerary from Kennewick to Las Vegas. This institute hosts a museum, art exhibits, and various events celebrating the people who have lived in this area for over 10,000 years. You can also shop at the museum store and get a bite to eat at the Kinship Cafe.
Roaring Springs Water Park
If you want to visit a water park, then Roaring Springs, which is billed as the Northwest’s largest water park, is a great option. Some great park attractions include Snake River Run, Corkscrew Cavern, and Thunder Falls. Once you’ve had your fill of the water park in Meridian, Idaho, you can head next door to Wahooz Family Fun Zone for some mini-golf, go-karts, and arcade games.
Aquarium of Boise
Not too far down the road from Roaring Springs is the Aquarium of Boise. At this attraction in Idaho’s biggest city, you can see more than 250 different species of marine animals in 35,000 gallons of saltwater. Hands-on animal exhibits and touch pools are also available at the Aquarium of Boise.
Shoshone Falls is often referred to as the “Niagara of the West” for good reason. This natural attraction located on the Snake River is 212 feet tall and 900 feet wide. A handful of pull-through RV parking slots give you a convenient, easy place to park your camper while you’re viewing this impressive Twin Falls site.
As you’re approaching Salt Lake City, you’ll first pass through Farmington and by Lagoon. This popular theme park has a host of rides, events, shows, and its own water park. Some great rides in this park include Cannibal, Colossus, Bat, and Rattlesnake Rapids.
Nampa’s the first big city you'll reach on your road trip from Kennewick to Las Vegas. It’s close to Boise and the Deer Flat National Wildlife Refuge. As of 2019, nearly 100,000 people lived in this city located close to Interstate 84.
Boise is the capital of Idaho, and it’s right down the road from Nampa. Nearly 230,000 people call Boise home. It's also home to Boise State University. Given its size, the high amount of quality dump stations, and campgrounds in the area isn’t surprising.
Salt Lake City
The next state capital you’ll go through is Salt Lake City. It has roughly 200,000 people living within its city limits. The Church of Jesus Christ of Latter-day Saints calls it home, so there are multiple important sites relating to Mormonism here. There are plenty of dump stations and campgrounds in the city and surrounding areas.
Provo is also important to the Mormons because it’s the home of Brigham Young University. Nearby Orem is also a large town; the Provo-Orem metropolitan area has more than 500,000 people living in it. If you want to explore this area, you can park your trailer at a variety of campgrounds.
