Well, I'm not sure what you mean by camping....there's camping at the various campsites in Yellowstone - some have services most don't. On the back page of the
seasonal newspaper is a list of the campgrounds and what they provide. My favorite one of these is Mammoth, but you have to get to these places early in the day cause they fill up fast.
This is a link to their back country guide if you want to camp in the back country.
And finally
this is a link to all their publications. YNP does a great job of putting out all sorts of planning information. HOpe this helps.
