Mammoth Campground

Great campground, well maintained. Hosts are friendly and amenities are great. Only issue I take is generator hours shutting you down at 8pm. Better have good batteries or solar generator to get you through the evening. Bathrooms were great. Make sure to obey bear rules, otherwise they will cite you. Traveling buddy almost got on 10 campsites away for leaving his grill out while he filled up on water. Otherwise great location, real close to Gardiner. Kind of a windy road but it has stuff if you need it.

Amazing place to stay inside the park. The sites are great, and the restrooms are well kept.

It was a good place to sleep. Wake up and see everything covered in snow, and soon after, about eight bison. It was spectacular. The showers weren't running, and only one bathroom was open during the winter season.

Love the tent pad, the easily accessible water and picnic benches. If there was anything to knock (and this is nitpicky) the tree coverage is fairly light though in fairness it is on the desert side of the park. Also it was a bit of a hike to deal with Grey water. We had a wonderful time though and the morning sun is shielded by the beautiful mountains. Birds and chipmunks are all over the place and sometimes there are visits from Elk in the campground. Hosts were great and it was very peaceful camping.

Love this park! It's close to the Mammoth hot springs and is open all year round. We were at site #22. Great views and the sites are big enough for 30 ft trailers. We drove around Yellowstone and encountered Bison crossing the road. Being that it was April 2, this was the only park open but it was still a great experience because it was not busy at this time. Would definitely come back again for mid April (15th) when all the other parks and roads open up.

The campground is mesmerizing with great views of the mountains just in front of the campsite! Great personal campsites with plenty of space, with a picnic table, bonfire place, and bear-resistant food storage bins provided!

Great location! So convenient to Mammoth and Lamar Valley. Camp hosts were so friendly and helpful. Sites are very large (we have a 34ft 5th wheel) offering good privacy. Plenty of places to fill up with water. So beware: there is road construction in the area and construction vehicles are super noisy traveling past the campground. Would suggest earplugs if tent camping. Lots of wildlife wander through this campground. Be aware and give them some space!

Fix your connection issues to have less problems with campers checking in. The registration system is unavailable to hosts and rangers. NPS is falling behind in this park. Time for needed updates. NPS do better. The campground is 5/5 the Hosts and NPS can only do what they can but management of the campground is 1/5. 3/5 is fair when comparing to other NPS campgrounds.

Although it rained most of the night. We still enjoyed our time at the campgrounds. Made the drive to yellowstone easy

We stayed here for the night before driving through Yellowstone. The location was amazingly convenient for us to explore the area. We arrived at night and quickly found where our tent was, as the initial email had all the details we needed. I liked how the tent site had reservation stickers on them as well, small but great touch. We sat by the fire and were able to see all the stars in the sky. It started raining late into the night and the sounds were relaxing hitting against the tent. When we woke up in the morning, the view was stunning. At night, we couldn't see anything, but in the morning, the sun was radiating over the mountains and canyons. A beautiful sight to wake up to. Overall, a great place to stay. The bathrooms were clean and the staff when we did meet them were friendly.

We stayed here at the end of September 2020 for three nights. We loved staying here and it was probably our favorite campground to stay at in Yellowstone. We arrived at about 6:30am and by 8:15am had a site. The volunteers were great about getting everyone a number in line so that even when they moved cars around out of line in order to fit everyone in the very short driveway, they could still honor who arrived first. There are three levels on the hill with campsites. The top and bottom are near the main park road and you can faintly hear cars passing by. The middle level is for tents, which is where we stayed in #73. Our site had a picnic table under some trees, a fire pit, bear box, and a leveled spot to pitch a tent. There was a potable water station right next to our site. There's a nearby bathroom up at the top of the hill with flush toilets and sinks (pretty well maintained for a campground). There isn't much privacy in any of the campsites, but that is made up for the fact that the views of the surrounding area from any site are beautiful. The Mammoth area has tons of elk walking around the village and campground. We visited Yellowstone during elk mating season, when the male elks get very aggressive. One morning when we were there, a campground volunteer was going around to everyone to make sure they were just aware of the fact that a young male elk was walking close to some tents and to give him some space. I thought that was extremely nice for them to care so much about the safety of their guests and to protect the wildlife (and yes, lots of elk hang out in the area! I even saw some ermines next to our tent early in the morning). Overall, I would definitely recommend mammoth campground for a lovely camping experience at Yellowstone.

There were a few things wrong with this campground starting with the generator hours being allowed only between 8am-8pm even though quiet hours are 10pm-6am. The reason this was a deal breaker for us was because we are avid explorers who want to make the most of seeing the park. Essentially every day we left the camper by 7:30 and returned after dark so we had no use of our generators At all. In addition, our 30' trailer was a squeeze into the spot we were given and we couldn't use the fire pit because it was less than 2 feet away from the camper in the tiny space. The worst part however is the noise from the surrounding roads, you feel like you are next to a highway all night! I guess that's what you get for $20 a night-which is why we left early. On the plus side-the bathrooms were very clean and well maintained and showers are available at Yellowstone Hotel which is a 1/4 mile walk from the campground by a footpath (cost $4.42). AdditonLly the boiling river and the hot springs are literally a minute up the road to the north and are a must do activity!
