About Mammoth Campground

The only campground in the park open year-round, Mammoth Campground—elevation 6,200 feet (1890 m)—is located five miles south of Gardiner, Montana and the park's North Entrance. Situated in a high sagebrush steppe, scattered juniper and Douglas fir trees provide shade during hot summer months. The campground is close to fishing, hiking, and the Mammoth Hot Springs Terraces. Great wildlife viewing opportunities abound with elk and bison occasionally passing through the campground.

ADA Access: Five accessible campsites, accessible routes along paved roadway, ramp to amphitheater. The North Entrance Wash Tub in Gardiner, Montana has public showers, including an accessible shower and bathroom. They have a ramp that enters at the side of the building. This would be the closest accessible shower facility to the Mammoth Campground.

We love Yellowstone & this location

Very good location, pretty level, fairly close to other campers but not terrible. We would stay here again.

Centrally Located

This campground is in the northern part of the park, so if you're coming in or leaving by way of Wyoming, this is the most convenient place to sleep! The bathrooms are very well-maintained and have running water. The spots, while they don't offer much privacy, are spacious especially if you have a tent instead of an RV. This campsite puts you at a prime location from which to explore the springs which are a major destination within the park. Since the campground is so close to the springs, you can get a leg up on the tourist bus crowds that start rolling in around mid-morning. The campsite is in a busier area and is surrounded by a road on both sides, so if you're looking for something a bit more remote, try Indian Creek or Tower Falls.

Conveniently Located

Get here early. The campsight is ran as a first come first serve and typically fill up extremly fast in the summer. There are a lot of rvs here but they are very strick on generator use at night. all in all, its a great location with a high change of elk walking through your site.

Boiling River Days

I love this campground because it’s super close to the boiling river and it’s cheap! Its first come first serve so you have to get here early in the summer to get a spot. We came here in late August and got a spot around 4pm. Mosts of the spots have a nice view and are pretty spacious. Be careful of the one with the unlevel tent pad. There is a great ranger program and the bathrooms are decent.

It was mostly ok

There was more privacy here than we were expecting, so that was good. The bathrooms were good, but often really far away. What really sucked though is that a common Yellowstone storm hit while we were away and blew our tent over and soaked everything. We were able to dry everything eventually, but I was a little disturbed that no one helped us, including not a single one of the 3 hosts on site, I also found them to be slightly on the rude side when we checked in. Bring guidelines and rope because there was no easy way to stake our tent in the rocky ground.

Functional

There are different loops on this campground. The loop that is always open, is basically in a field. Blah. The other loops, are in some trees, and often have elk roaming through camp, but they are only open during peak season. Speaking of which, good luck ever getting a spot at this campground. If you do manage to, it is close to Mammoth, and also close to Gardiner… it can make a good base camp for exploring the Northern half of Yellowstone National Park.

Such a great place to rest at the end of a long day exploring the park.

Get there super early during peak season it fills up fast. Take a moment before bed to listen to the informative ranger talks it was very informative.

Great views

This camping area is really close to restaurants and stores within Yellowstone, and is only a short drive from the north entrance of the park. We used this site as a base to explore North East Yellowstone. It can be easily reserved early mornings, and the places to set tents are leveled and dry, although someone thought it was a good idea to add lots of stones to the ground where the tents are set. Nice restrooms are close, and lots of elk and other wildlife wander around the area. Highly recommended!
