Do you remember when you were a kid and your family loaded up the car to go across the country to go see Yellowstone? Well, Yellowstone is still there and it's time for you share the wonders of the World's 1st National Park with your own family and friends. At Yellowstone Park/Mountainside KOA Journey we offer a full range of camping options for RVs and tents as well as our deluxe cabins. We're even next door to the West Yellowstone Super 8 Hotel for those folks that still want to be part of the fun but want to stay indoors. Since we are only minutes from the West Gate of Yellowstone, we are perfect place to stay for a few nights and re-explore Yellowstone and make some new memories with family and friends.


We can cater to any size group from just a couple of families up to groups of 200+. We have a unique 1,500 square ft. square dance hall available for use that has a full kitchen and is home to an array of old square dancing memorabilia stretching back into the 1960s. We also have an outdoor pavilion that can seat up to 100 more people that is covered and comes with a large firepit and BBQ grill. Horseshoes, volleyball and a brand new playgroud round out the activities on site in addition to the access to the nature trails leading into the beautiful Gallatin National Forest. We can cater meals if you need and also have the Lodgepole Pizzeria onsite serving handmade pizza and other entrees nightly.
