The most important point is that the campground is three miles from the Yellowstone Park East Gate. The East Gate is 26 mi from the Grand Loop junction at Fishing Bridge. Many people stay in Cody Wyoming, but it is 49 mi from Three Mile Campground. Do the math. You will be driving all day.
The campground is very well organized. The camp host was very helpful and present. The sites were pull in and back in and several of them could accommodate longer rigs. The loop around the campground is easy to navigate and the sites are well marked. The amount of shade on the sites varies. Site #3 is void of shade and should not be selected in the summer months. Our sites, #2 and #5 were practically level and required very little adjustment.
There are no phone signals or WI-Fi services in the campsite. This is a Dry Camping experience seen in Most National Forests.
We stayed in Three Mile Campground in a 25 ft Motorhome.
