Mammoth Campground is a great base of operations if you are exploring the North Section of the park. There isn't much for trees so your privacy is LOW. It is a little on the noisy side as you share your space with plenty of RVs and generators. But the scenery is breath taking, and its very handy to have the... More

We were surprised to find that there weren't showers at this campground. We found out later that the showers at the Mammoth hotel are open to people who are camping. Our site had plenty of space for our two-person tent and vehicle, and then some! We didn't spend a lot of time at the campground-we mostly just slept there. It... More

And I actually enjoyed it, our 1st choice of Canyon was filled fast so we got our 2nd choice. I thought the location was perfect and our site was very big, much better than anything we have had at a KOA size wise. It was extremely windy and got down to the low 30's but we were warm and slept... More

Almost the perfect campground. Not too many sites, excellent for RVs as spaces easy to get into and not close together. Water at most sites, excellent views, close to hot springs and Gardnier. When it is snowing in June or July or even August, this is the place to be. 10-15 minute easy walk up to Mammoth. Our favorite campground... More

I loved it here. We stayed 6 nights in a great pitch set back and uphill from the road (which gets busy from 6am onwards) overlooking the valley. It's less than a mile to get to mammoth springs where there are showers and concessions. Also you can get out to Gardiner really easily for shopping and laundry/internet. You have to... More

We stayed in this campground for 2 nights in September. It's warmer than other campgrounds because the elevation is lower. It's close to mammoth hot spring. Visitor center, restaurants and general store are close by. The campsite is spacious and there is no time restriction for campfire. Every morning, a herd of Elks come here to eat their breakfast. You... More

Spent two nights here while touring the northern part of Yellowstone National Park. This campground does not take reservations; simply show up and check with the volunteer camp hosts to see what's available. We arrived around 9 a.m. and secured tent site #85, a spacious site with a parking spot, picnic table, campfire grill and, lucky for us, a gravel... More

This NPS-run campground is a great alternative to the many run by Xanterra, the private concessionaire. Not only is it substantially cheaper, but it's a more reasonable size (under 100 sites) and is staffed by great volunteer campground hosts. There aren't many trees, but the views north toward Gardiner are great. Be prepared for the ground squirrels to start squeaking... More

We stayed 2 nights here & 3 at Bridge Bay. We got here early & were able to pick our spot. Check in is quick & easy. Campground was clean yet rustic. The mountains were right across the road from us. It was the best of both worlds - camping in the mountains yet close enough to modern conveniences.The road... More
