Our only year-round campground, Mammoth is located five miles south of Gardiner, Montana and the park's North Entrance. Situated in a high sage brush steppe above the Gardner River, scattered juniper and Douglas fir trees provide shade during hot summer months. The campground is close to fishing, hiking, and the famous 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 (5 miles north) 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.
The campground itself is very well maintained and clean with water spouts everywhere, garbage dumps, and (clean) flushing toilets. All pull thru sites which are very spacious. No reservations so keep that in mind, just get here early and you should haven't a problem getting in 😁.
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.
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.
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.
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.
had a great time visiting and loved the area so much to do and see
This campground is always open, but how busy it is always seems to change with the season.
Right by the north entrance and Mammoth Hot Springs (which is awesome) and you'll almost always see some elk, but not as close to other "main" attractions so people will pass it by. Sites are a bit open, so you're not as secluded as some of the other campgrounds in the park, but they make up for that by being bigger than the other sites (which unfortunately can attract some pretty large RVs).
Because you don't have the shading of the forest like other sites it can get pretty warm. You have picnic table and fire ring with potable water and running water facilities.
Mammoth campground is the only campground open all year round. It's not as big as Bridge Bay or Grant Village, in fact it is one of the smallest campgrounds in Yellowstone National Park. It is right by the Mammoth Hot Springs Hotel, the Albright Visitor Center and the North Entrance. There are quite a few short hikes nearby. If you want an easy one mile hike checkout the Boiling River. The parking area is just north of the Mammoth Hot Springs. It's Yellowstone, no campground here can be less than four stars!
Beautiful views from the campground, saw some elk nearby as well. Good spot for seeing Mammoth Hot Springs or hiking in the northern areas of the park. We went to Gardiner, MT one evening for a small bluegrass band as well which was a highlight.
