What Guests Are Saying
Mammoth Campground offers clean facilities, friendly staff, and a beautiful location near Mammoth Hot Springs, making it an excellent base for exploring Yellowstone. Many reviews highlight the well-maintained bathrooms and accessible water spigots, as well as the stunning views and quiet atmosphere. However, some campers noted a lack of shade, noise from nearby traffic, and limited trail access, but overall, the campground is highly recommended for its amenities and scenic surroundings.

We loved the campground! It is tiered so you have a clear view of the beautiful hills at most sites. This also makes it feel more private. Most (maybe all?) sites are pull through which was great. No showers on site, there’s a laundromat that has 3 showers in Gardiner, and it cost $5 (in quarters-they had a change machine) for 10 minutes. Bathrooms at the campground were clean and nice though. Bear boxes at every site. Elk walked through the campground a lot which was cool for the kids! Great location to get to town (Gardiner) or head right into Yellowstone on the top of the figure-8 Grand Loop. There is road noise because you’re right in the corner of a switchback, but we still loved it for the location and view!

Our stay at Mammoth was very lovely! It was small enough not to feel cramped and the restrooms were really nice. Bear box and grills in every campsite was nice. Excellent views!

So loud - there was construction going on up the road so all night long semi trucks were going up and down the hill. It really took away from the peacefulness of the campground. On top of that, our site was closest to the bathrooms so people were walking through our campsite to get there and also caused a lot of noise. We barely slept the first night we were there because of the noise (I woke up every 4 minutes for several hours), so we ended up leaving a day early because we didn't want to listen to semi trucks all night again. Other than the noise the campsite is nice, but there's not much room for the tent sites. Be careful driving on the one way road through the sites. When we were there people we not following one-way rule and we almost got hit head on a few times.

Super wonderful camp hosts, lots of nearby hikes, and prairie dogs and elk are everywhere. Absolutely amazing experience..the only thing that was a bummer was being next to the road and all the construction trucks come through 24/7. But other than that an amazing time

The view from the campground is beautiful. Very clean and well-maintained facility. The staff was very friendly and knowledgeable about the area. The only drawback is no dump station at this campground. If you plan, it won't be an issue.

This campground is in rough terrain with very few trees so it does get hot. The campground host were awesome, super friendly and helpful. This site gives you full access to the old military outpost and the village of Mammoth Springs (try the ice cream at the general store!). This site also gives you easy access to Gardiner, Montana which is the closest area to get wifi and cell service if you need to check on things back home. We spent a day exploring the Bear Tooth Highway and loved it!
