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.

It was great to be so close to the Mammoth Hot Springs. We had a cool view at our campsite.

Nice campground just outside town. All sites are pull throughs. Good open views. Only a few sites have a good spot for a tent.

We enjoyed our stay at Mammoth, the camp hosts were very friendly and even helped fill our tent trailer water tank from their site when our tap couldn’t fit the hose. Gardiner is only 5 miles away and we enjoyed a good meal at Wonderland Cafe. The campground is very close to the Mammoth Hot springs so we were able to explore the upper and lower areas later in the evening with less crowds. After our stay we drove the upper loop to Tower Falls across the Dunraven Pass with no problems.

Great campsite next to an amazing village. Great mountain view. Amazing. The best campsite we've ever stayed in the entire Yellowstone.

Campground hosts failing to maintain bear safety regulations. Large amounts of wildlife attractants available throughout campground including when everyone is aslepp- this includes food preparation gear, coolers stacked OUTSIDE bear boxes, and more. I am following up with regional officials to stop the sloopy management of these campgrounds before someone is killed and a bear has to be destroyed.

Beautiful campground with easy walking access to Mammoth village and Fort Yellowstone from the amphitheater area. Wildlife viewing and v clean bathrooms (not vault toilets!) a plus. Sites are small but well designed so you don’t feel like you’re right on top of your neighbor site, which was nice in the busy season with full sites. The generator free times were appreciated by us tent campers!

Beautiful views of the valley at every site. Host was very friendly and helpful at check-in. Site was clean, level, and the nearby bathhouses were nicer than I’ve seen in similar campgrounds. Would absolutely camp here again.

We love national park campgrounds. We wish those with reservations they cannot make would cancel rather than just not show up, so those waiting for a site could get one. Each campground we have stayed at has had 5-7 no shows which were not cancelled so the site could not be used by someone else. We wish there was some way you’d give away sites that no on shows up to. Other than that, Mammoth was one of our favorites. Thank you.

This campground is really convenient because of its proximity to the Mammoth hot springs. It also looks out over a really beautiful valley. However, the tree coverage isn't great during hot summer days. It's also not really a secluded campground, so if you're looking for a campground that feels like it's in the middle of nowhere, you may not want to choose this campground. That being said, the bathrooms are great, the views are beautiful, wildlife is nearby, and the camping spaces include plenty of space. We enjoyed our time here.

Great to sleep inside the park. The campground was clean, with a nice view on the hills around it.
