Yellowstone Park / Mountainside KOA

Explore Yellowstone from the perfect base camp!

Welcome to the Yellowstone Park / Mountainside KOA!

Yellowstone National Park is just 7.5 miles down the highway from this KOA. Old Faithful is 37 miles away. Along with the striking scenery of the rugged Continental Divide and stunning views into Yellowstone, you can soak up the natural beauty of the campground's meandering mountain streams, fishing ponds and grand old-growth lodgepole pine trees. Big rigs enjoy some of the area's longest and widest Pull-Thru RV Sites. Camping Cabins tuck right in among aspen and willow trees along the banks of Denny Creek. Hiking and four-wheeler trails lead off from the campground into Gallatin National Forest. Wildlife viewing - for moose, elk, bison and more - is excellent. Groups enjoy the indoor and outdoor pavilions. Max pull thru: 105 feet.
