The Best in West Yellowstone RV Parks - Yellowstone KOA Moun

Yellowstone KOA Mountainside Campground is among the highest rated West Yellowstone RV Parks and provides quick and easy access to Yellowstone National Park. Our RV Park, Campground and Rental Cabins are tucked in the Gallatin National Forest, just seven miles from the west entrance of Yellowstone Park.

With picturesque mountain views and a wide range of amenities and nearby activities, Yellowstone KOA Mountainside offers full service accommodations with ample amenities for every type of outdoor person.


We are in the beautiful Rocky Mountains, which means we have very limited internet. There is just enough bandwidth to check an email or lookup a restaurant. Please do not upload/download photos, stream or download audio/video. Come into the store to get the password. Thank you and enjoy your stay!


Our laundry is open 24 hours a day but get your change in the office during regular hours.


We have bears in the area due to the nature of where we are located. We ask that you keep all food, trash, coolers, and grills inside your RV, cabin, or car whenever you are away from the campground and at night to keep them from wanting to come onto the campground. By following these rules you can help keep yourself and others safe. Thank you!

Meet Your Hosts

The Linde family

We know that a trip to Yellowstone is a once in a lifetime thing and we want to help you make the most of your time here.

Since 1982, the Yellowstone National Park KOA was in the Linde family. Avid campers themselves, Steve Linde has worked at this KOA since he was a child and now shares the opportunity of working at this great location with his wife, Laurel, and their 3 boys. Surrounded by beautiful scenery at Yellowstone KOA, the Linde's KOA focuses on customer service, and they have many repeat customers. Steve and his wife are there to be sure each customer is happy. "We have over 30,000 campsites occupied in a four month season, most of which visit from late June to early August," said Steve. They support a large seasonal staff, and Steve added that his KOA challenges them to recruit new employees. The campground also employs a staff of full time employees, and their concentration in the off-months is consistent renovations. Steve said, "staying up to date" is a top priority for the Linde's and modernizing helps their campground to accommodate all visitors. Steve is proud that they come up with many new ideas that other campgrounds can use to improve their sites. If one is in search of a friendly, fun park, then Yellowstone KOA is the place. "There is something going on every other night," said Steve. Because of the constant renovations, Steve mentioned that his campground is "big rig friendly." Often times a site will have two ready ducts for RV's instead of the usual one. In the off season, the Linde's spend time in Billings, Montana. When Steve and Laurel are not working, Steve enjoys bow hunting and Laurel is an accomplished musician who plays the clarinet.
