What Guests Are Saying
Mammoth Campground is praised for its beautiful scenery, convenient location near Lamar Valley, and friendly hosts who maintain a clean environment. Many campers enjoyed the spacious and accessible sites, as well as the wildlife sightings, particularly elk and bison. However, some visitors noted that only one bathroom was open during their stay, leading to inconvenience, and there were occasional issues with campsite reservations. Overall, it's considered a great spot for exploring Yellowstone, especially in the off-season.

Awesome camping ground with beautiful views and close to mammoth hotel and other facilities like gas stations and ect. Perfect camping ground if you are traveling with kids.

During our stay in June 2024, Mammoth Springs Campground impressed us. Despite being fully occupied, the atmosphere remained pleasant and respectful among campers. Generous spacing between campsites provided privacy, and the view of the hillside across from the campground was both peaceful and mesmerizing. The morning birdsong at sunrise added to the natural charm. Additionally, the shared bathrooms were clean and conveniently accessible.
Overall, Mammoth Springs Campground is a great choice for families seeking a tranquil outdoor experience. 🏕️🌲

Raised tent platform is a great idea. Rangers were both friendly and helpful. After seeing a bear near the campsite, it was comforting to see constant patrolling by rangers. Bathroom was clean and portable water was available. Dump station and WIFI is needed.

I loved this campground. The views were breath taking. We had elk come right up into our campsite while we cooked our dinner. The bathrooms were well maintained. I would stay there again.

We love Mammoth campground, clean, concerned staff although the older campground host seemed overly suspicious when we checked in. She needs to chill a bit.

I love the level site for my 8x8 tent.
It would be great to have some facilities for dish washing as other campgrounds in the Yellowstone National Park. Given the likelihood to attract bears, we cannot wash/pour used water outside, yet we need to cook.

Realize that distances in the park may seem short....i.e. 20 miles...but that can take much longer than highway or freeway miles. Slow moving traffic ahead of you that doesn't use pullouts, bear or buffalo jams can stop you for extended periods of time. Come with patience and follow park rules about distances from certain animals, etc.

This was a great campground. The area was clean and well maintained. Restrooms were in good order. Most of the noisy RVs and youth was quiet at a reasonable hour. The staff working there were very, very friendly and our site was quite large. We used a tent and they had dedicated tent pads for our site that were soft and level. I watched other people try and pitch larger tents, and they did not fit the pad. Ours was a 4-person tent and fit just fine, that might be the limit. The fire pit was right on the driveway, so you might have some issues with smoke in your car or whatnot. The were hiking trails nearby, wildlife running through the campground and Mammoth Springs is next door. In MS you can find basic supplies and shopping, a restaurant or two and the visitor center. The actual springs are on the other side of the village so there are some good hikes with geysers. The town of Gardiner is a short drive for major resupply. Unfortunately, just after we left, major rain did a lot of damage to this area and that town…hopefully everyone is ok and they are able to rebuild the area.
