What Guests Are Saying

Mammoth Campground offers clean facilities, friendly staff, and a beautiful location near Mammoth Hot Springs, making it an excellent base for exploring Yellowstone. Many reviews highlight the well-maintained bathrooms and accessible water spigots, as well as the stunning views and quiet atmosphere. However, some campers noted a lack of shade, noise from nearby traffic, and limited trail access, but overall, the campground is highly recommended for its amenities and scenic surroundings.

My visit was lovely. The camp hosts were excellent. My only complaint is my camp site. It had originally been a camp site for tent campers. I parked my 24 foot in the assigned spot with no problem as far as my length or width. The problem was the inability to level my unit. That’s hard on heating and cooling devices. Needed a little more room to level out.
