We stayed at Canyon Campground on our 3rd night in the park. It was great for being in the middle of busy Yellowstone! If you have been on a long journey and are a bit tired of using camp suds in a dry sack for laundry then you should swing by at least for the laundry services. There are over 250 sites available and some are available for reservations. There is a general store and restaurant near by as well. Not the place if you are looking to get away from it all but a nice welcome back to civilization after time in the backcountry. It is pricey for a campground coming in at over $25 per night, but cheaper than area hotels by far! Plus that includes 2 free showers each night. The nearby visitor center has a great exhibit about the volcano that will scare the pants off of you LOL It is a quick jump over to the upper and lower falls and the grand canyon of yellowstone. Great location for those looking to get around the are and see a lot while not always being completely stinky and eating dehydrated food out of baggies :)
