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!

We had the best time at Mammoth Campgrounds. We were there in early May when temperatures were still 40 during the day and 20 at night. Even though we were in camping spot #3, right next to the entrance, we were never bothered by road noise or traffic. The best part of this campground is the bathrooms!! They are by far the best bathrooms from any National Park; well-lit, heated and flushable toilets. We were here four nights and loved every day of it!

Absolutely wonderful! We had a great stay. There were sites that fit our fifth wheel without an issue. Nice views and loved the elk! There is a bit of road noise because of location but that didn't really bother us since we were exhausted at the end of every day. One of our favorite areas of the park to be sure!

Awesome views. Nice proximity to the historical town (Mammoth) and Gardner (outside the park). Sites were small but easy to navigate. Unfortunately no place to wash dishes or shower. The campground did suggest a place in Gardner though. Not all sites have a gravel leveled area for tents. It was nice being in the park and not having to deal with the gate. Felt overpriced though for the amenities it provided. Especially when compared to other National Park campgrounds I’ve been to.
