Mammoth Campground — Yellowstone National Park
Reviewed Oct. 16, 2021

Great Campground - Lots of Wildlife - No AT&T Service

Great campground with plenty of sites (keep in mind this is October) but I arrived at 7pm and had no problem getting a spot, it was $25 for the night. Bathrooms were clean and flushing toilets were nice. Woke up in the morning to an elk in my campsite eating off some trees, very cool way to be greeted.

One thing to note at this time there was no AT&T service at the campsite so I had to leave the park and drive into the town to the north (about 15 min) to get service.
