What’s more, the park is conveniently accessible via Interstates 90 and 93 and, when you need to top up supplies, the county seat is just a mile south.

The Great Outdoors

If you’re looking for recreational activities in a breathtaking setting, then Bighorn Canyon National Recreation Area will definitely be on your RV rental vacation itinerary. The 12,000-acre area hosts a variety of wildlife, diverse ecosystems, and a plethora of land and water-based sports. Here you can enjoy fantastic panoramas from a 1,000-foot-high overview or visit the impressive Yellowtail Dam. Bighorn Canyon National Recreation Area is also home to bighorn sheep and one of the largest herds of wild horses in the USA.

There are over 17 miles of scenic hiking trails to explore which range from short and sweet to long and challenging. You can hike or bike through juniper trees and sagebrush on the Bad Pass Trail. This historic route was regularly used by American Indians to travel between the Northern Plains and the Bighorn Basin. Another option is the gentler Hillsboro Trail which traverses the colorful Trail Creek Valley. Bighorn Canyon is also a prime spot for boating. You can canoe or kayak on Bighorn Lake or paddle between dramatic canyon walls. Visitors can find boating equipment at marinas near Lovell and Fort Smith.

Another place to visit when you rent a camper near Hardin KOA is Pictographs Cave State Park. It’s located close to Interstate 90, just outside of the small city of Billings, MT. This prehistoric site is made up of three main caves which were once the homes of Montana’s first human settlers. These hunters carved their primitive abodes into the sandstone cliffs, and in 1936, the first of their weapons, paintings, stone tools, and other instruments were discovered. Visitors are invited to view all three caves using a ¼-mile-loop trail. The most archaeologically significant is the Pictograph Cave, which is the deepest and designated as a National Historic Landmark.

When you’re ready to take your campervan rental for a spin, turn your vehicle toward the Beartooth Scenic Highway. Winding for nearly 70 miles through northwest Wyoming and southwest Montana, this National Scenic Byway offers magnificent views of the Beartooth Mountains and direct access to Yellowstone National Park. From the comfort of your rental RV, you can see glacial lakes hidden between alpine plateaus and forested mountain slopes. Look out for waterfalls and wildlife as you drive or park at the Beartooth corridor for some hiking, wildlife watching, and winter sports.
