Yellowstone/ Mountainside KOA Journey

Overview

The Yellowstone / Mountainside KOA Journey serves as a scenic and functional basecamp for explorers visiting the nation’s first national park. Located in the crisp high-country air of the Madison River Valley, this park offers a more relaxed and rustic atmosphere compared to downtown commercial strips, while maintaining the reliable standards of the KOA brand. It is a convenient road-trip stop specifically designed for travelers who prioritize proximity to nature and ease of access to iconic regional landmarks.

Location & Surroundings

Positioned just 10 miles west of the town of West Yellowstone, the park sits nestled within the Gallatin National Forest. The surrounding landscape is defined by sprawling mountain vistas and the nearby Madison River, which is world-famous for its fly fishing opportunities. This location allows guests to escape the heavy congestion found directly at the park gates while remaining just a short drive from the Yellowstone West Entrance, making it an ideal spot for those who enjoy mountain scenery and quiet nights.

Amenities & Park Features

As a Journey-branded property, this KOA focuses on providing the essential features for a comfortable and efficient stay. The grounds are designed with spacious pull-thru sites that make setup simple for drivers of large motorhomes and fifth wheels. Key amenities provided at the park include:

  • Reliable full hookup connections including 30 and 50 amp service and clean restroom facilities.
  • On-site laundry services and a well-stocked general store for essential supplies and souvenirs.
  • A dedicated Kamp K9 pet area to ensure four-legged travelers have a place to exercise.
  • Functional Wi-Fi access and available firewood to enhance the traditional evening camping experience.

Nearby Attractions & Things to Do

The primary draw for visitors is undoubtedly Yellowstone National Park, where guests can witness geothermal wonders like Old Faithful and the vibrant Grand Prismatic Spring. Just minutes from the campground, travelers can spend a day at Hebgen Lake for boating, paddleboarding, and swimming. For those interested in local wildlife education, the Grizzly & Wolf Discovery Center in West Yellowstone offers an up-close look at regional predators. The area also boasts miles of hiking trails and some of the finest trout fishing in the Rocky Mountains.

Who This Park Is Best For

This facility is perfectly suited for active explorers who view their RV as a mobile headquarters for outdoor adventure. It is an excellent choice for adventure-focused travelers and families who want to stay close to the action of the national park without the noise of a busy town center. If you prefer a quiet, mountainside setting with straightforward amenities and quick highway access for early morning departures into the park, this location fits your travel style perfectly.

My husband and I stayed at this location for over a month while he worked in Big Sky, so that kinda makes me an expert! :) The location is so beautiful, and conveniently located so close to bars/restaurants, a small food market, and of course to the west entrance of Yellowstone NP. All the staff we encountered were very friendly and helpful. As travelers who move around for work, our schedule changes often and last minute, and we’re grateful for how understanding accommodating they were. Their facilities and amenities are very well kept. Overall, we enjoyed our stay immensely and would recommend other travelers check it out!

We stayed here for one night at the end of September. Our check in was very smooth and our site was great. Everything was very clean, it was easy to pull through and hook ups were great. The bathrooms are extremely clean and have good hot water for showers. The staff were so friendly and helpful. We can definitely recommend this great KOA.

This was my first time at this establishment. I reserved ahead online with no problems. We stayed Tues, Wed and Thur night the first part of September. It was pretty full for the most part. We did get a tent site right by the creek which was awesome. It was a short walk to the bathroom/showers. They had a laundry room and a store though I never did get to go in. The campground was very neat, organized and the bathrooms were very clean and up-kept. I definitely recommend and would stay again.

The campground is well kept and everyone on staff has been very nice. If you need anything they are very accommodating..... I needed to get on top of the roof of my camper and within minutes one of the staff had a ladder here 💯 The bathroom/showers and laundry facilities are definitely a five-star. We ended up booking an extra week and stayed here 2 weeks. they have a couple of ponds out back that you can walk around and a really nice creek with bridges that you can sit on and listen to the water. We've seen deer, and moose walking across the top of the meadow outback. We have absolutely enjoyed our stay here at KOA

This is an overall nice park with good typical hookups. Top notch general store with lots of things you would need. The people working here are very friendly and helpful. I am marking this at three stars for 2 reasons. This is one of the most dusty places I have ever stayed in. If you have a freshly washed coach you will leave with everything covered including inside if you leave any windows or doors open. It would be wonderful if the roads were at least asphalted of they would occasionally water the gravel down. The employees drive noisy gators around at almost all hours and nobody seems to drive slow. It is not an inexpensive place so I expected a bit more
