Yellowstone National Park, Wyoming, Montana, and Idaho

Yellowstone is one of the most sought-after National Parks in the Western United States, and we understand why. The park sits on top of an inactive volcano and has more hot springs and geysers than any other place on the planet.

The 3,500 square mile wilderness recreation area is mainly in Wyoming. But it also spreads into parts of Montana and Idaho. You’ll be greeted by lush canyons, forests, alpine rivers, geysers, and the most famous, Old Faithful.

The park is also home to many wolves, bears, bison, elk, and antelope. Parking your RV won’t be an issue because there are five campgrounds within the park! Just remember to check for any length restrictions.

And be aware that Fishing Bridge Campground is the only one that has full hookups. There are private campground options outside of the park, as well. But you’ll want to reserve a spot ahead of time to ensure you can stay when you want.
