We are new to camping and new to camping near wildlife. We were very impressed at the lengths the Yellowstone rangers go to in order to secure the safety of campers at the Mammoth Campground. We genuinely appreciated the abundance of caution that is taken and enjoyed the peace of mind that following the carefully curated rules brings. We loved the setting of our campsite. Plenty of friendly people around, just enough open space, and just enough privacy. When we return to Yellowstone, we'll pick this campground again! Thank you for a wonderful stay.

Nice pull through site, minimal shade yet private. Tent pad has quite a bit of slope to it. To the point that we did not use it.

Great site with 2 large trees for shade, great bathroom facilities with flush toilets and easy access to the Mammoth Hotel for much needed showers after a long day of hiking! Do bring extra blocks as this site has a bit of a up hill slope to it on the west side.
