Nearby National Parks

With nearly 3,500 square miles, the park is home to both mountain peaks and deep valleys. You can head over to Old Faithful and see it erupt before hiking the Mallard Trail or the Fairy Falls Trail. Yellowstone National Park has multiple campgrounds where you can stay and several restaurants, including the Grant Village Dining Room and Cafe Madriz.

Grand Teton National Park

Once you reach Casper, consider taking a day trip to Grand Teton National Park near Jackson. This gorgeous park is open year-round and features several public and private campgrounds. You can hike any of the Jenny Lake Trails, such as the Hidden Falls Trail or the Forks of Cascade Canyon Trail. There are also several trails that lead around the other lakes and the Laurence S.

Nearby State Parks

Lucky Peak State Park

On your way out of Boise, stop by Lucky Peak State Park, which is an Idaho state park close to the Boise River Greenbelt. It has several off-leash areas for your dogs and a boat ramp close to the Spring Shores Marina. The Junior Ranger program is open to kids of all ages and offers activities all year. You can also try your luck at disc golf on the on-site course or hike one of the trails near the water.

Eagle Island State Park

Located in Eagle, Idaho, Eagle Island State Park is another Idaho state park that is just a short detour off the highway. The swimming beach is the perfect place to cool off on a hot day, and the trails offer more than five miles of space for you to walk or to take a horseback ride. Though the snow hill is great for winter sledding, it turns into a zip line during the warmer months. You'll also find a waterslide that allows you to buy tickets for a single ride or for all-day use.

Edness K. Wilkins State Park

As you head into Wyoming, plan a day trip to Edness K. Wilkins State Park. Just six miles from Casper, this Wyoming state park has more than 40 areas where you can enjoy a picnic lunch in the shade. Before sitting down to a meal, visit the volleyball courts or horseshoe pits for a quick game. The nearly three miles of trails in the park are suitable for people of all ages and let you get close to the North Platte River.

Along the Way

Independence Rock State Historic Site

Nicknamed the Register of the Desert, Independence Rock State Historic Site has the names of more than 5,000 of the pioneers who passed through on their journeys west. M.K. Hugh initially signed the rock in 1824 and created a landmark for those who followed. Sitting more than 130 feet above the ground, the rock continues welcoming guests today. Once you stop for a visit, head towards Devil's Gate for an impressive view.

Science Zone

People of all ages can learn more about science at Science Zone in Casper. It is an interactive museum with tons of hands-on displays and exhibits. There is a small area filled with animals where you can learn about native animals and those from around the world. The activities that are available change with each season.

Fremont Canyon

Fremont Canyon is one of the best places to get close to nature – if you don't mind getting off the beaten path. While there are some paved roads, many of the trails are not paved and are occasionally difficult to reach. Fremont Canyon has a maximum depth of 500 feet and is popular among adventure sports enthusiasts. You'll find locals who rent all-terrain vehicles and other equipment to explore the canyon.

Hells Canyon National Recreation Area

Hells Canyon National Recreation Area is part of the Wallowa-Whitman National Forest. On your Boise to Casper RV road trip, stop by to explore the more than 650,000 acres of open space. Heavens Gate features a small campground and a trailhead that lets you get deep into the wilderness. Other parts of the recreation area that you may want to explore include Winy Saddle and Black Lake.

Casper Planetarium

When you reach Casper, head over to the Casper Planetarium for a unique look at the sky. Though it closes a few days a month for cleaning, most days include live shows that are open to the public. You can watch a show about Galileo and others from his time period or view a show about the dinosaurs that once lived in the area. The planetarium has an online schedule that lists all upcoming events.

Main Cities You Will Pass Through

Mountain Home, Idaho

Known for the military base within its limits, Mountain Home is a great place to take a break. The downtown area features many historic buildings that date back to its early days that now house shops and restaurants. It's close to the Bruneau Canyon that covers 60 miles and the Mountain Home Museum, and there are a number of campgrounds in the area. Make sure that you take time to visit the historical sign that marks the start of the Oregon Trail, and dump stations are also available in the area so that you can start your trip with clean tanks.

Twin Falls, Idaho

BASE jumpers love Twin Falls, but so do those who prefer to keep their feet on solid ground. This small town makes it easy for you to get to Snake River Canyon on your Boise to Casper RV road trip. The Herrett Center for Arts & Science has fossils and exhibits dedicated to dinosaurs and other early creatures, and the Canyon Springs Golf Course lets you play in the middle of a canyon. It’s easy to find one of the top campgrounds in Twin Falls before your trip, some of which are close to the top Idaho dump stations.

Lava Hot Springs, Idaho

Named for the hot springs that run through town, Lava Hot Springs is a small town in Idaho that only has around 500 residents. The top reason to visit is for the pools that get heat from the natural springs, and because visitors come from all around to visit this attraction, campgrounds and dump stations are easy to find. You can take a dip in the Olympic pool or head over to the hot pool and enjoy the warmth. Temperatures in the pools range from 102 to 112 degrees Fahrenheit. With diving platforms and water slides along with a gift shop, this town offers fun for the whole family.

Kemmerer, Wyoming

Kemmerer offers loads of things to do, including the Fossil Country Frontier Museum and Fossil Butte National Monument. You have the chance to look for fossils and find souvenirs that remind you of your Boise to Casper road trip. The Green River Recreation Center offers different activities for kids and has a swimming pool that is open during the warmer seasons for visitors of all ages. Kemmerer is in a more remote location, so there are Wyoming campgrounds and dump stations where you can stay. 

Lander, Wyoming

Not far away from Kemmerer and close to Casper is the small town of Lander. It's close to many of the best and cleanest dump stations in Wyoming that you might need on your trip. The Lander Children's Museum is home to hands-on exhibits designed for kids and features different daily activities. Those with an interest in history like the Fremont County Pioneer Museum, which has artifacts and displays that show what the early pioneers endured.
