The Great Outdoors

Montana is national park country, and there are plenty of them to enjoy. Yellowstone National Park covers 3,500 square miles and features stunning, unforgettable views. From the rushing waterfalls to the dynamic canyons, whether you’re hiking, mountain biking, off-roading, or horseback riding, you’ll definitely have to stop and stare from time to time. Check out the boardwalks by the thermal basins for some unique sights that showcase the mud spots, hot springs, geysers, and fumarole. Learn more with a ranger-led program and grab a camping spot so you can see it all.

Then you can jump in the rental RV and see how the park compares to some of its lesser-known neighbors that offer their own breathtaking sights.

Here you'll find a massive collection of dinosaur bones, and rotating exhibits and the Taylor Planetarium mean there’s always something interesting to see.

For even more animal observation, you can take your West Yellowstone RV rental over to Idaho Falls and check out the Idaho Falls Zoo at Tautphaus Park.
