I was able to snag a spot at Canyon Campground for few days at the height of busy season. (I kept the campground reservation page open on my computer and would refresh every hour. I had one campground per tab. Finally got a cancelation at Canyon, so took it. But it can be done!!)

Our spot was pretty small and right by a water spigot that everyone used, so that was a bit annoying. Lots of small pine trees make it feel more spaced out. Luckily, there was no one camped behind us (no spaces there), so that was nice. We were situated near a screaming kid, so that was not so nice. Not the campground's fault though. It is what it is.

Big bear box to hold everything, but we were told it is also fine to lock stuff in your car. (The bears here allegedly don't break into cars like they do at Yosemite.) Nice picnic table and fire pit. Bathrooms have flushing toilets and a nice room for dishwashing. 

During COVID, the showers down at the shower room by where  you check in are closed. So no showers for us. (If this is important to you, check the Yellowstone NPS site to see if and when they reopen. Showers at all the campgrounds in the park were closed.) They did kick back a couple bucks per night for the lack of showers.

We were able to find a flat enough area for two 2+ tents, but there's no official tent pad.

My favorite part of this campground? You can hear the thundering Yosemite Falls in the distance. Best white noise ever!

Least favorite part of the campground? The bathroom lights are always on, so if you are in a site near the bathrooms, you always have light shining into your site from that building.

There's ice, firewood and a camp store down by the checkin. There's a place to drop off trash and recycling out front, as well.

From our loop (E), the village was a long walk or short drive. I have Verizon and got an okay signal (one to two bars) in camp and a much better signal in the parking lot of the village. (As a professor, I did go down to the village parking lot a couple of evenings and used my phone to create a hot spot so I could do some grading for an online summer class.) 

In the village, the cafeteria seemed to be open until about 10pm. One night, I took a little drive around to Yosemite Falls (no crowds late in the day!) and came across a black bear by the road into the falls, which was cool.

Note that all of this was during COVID times, so it wasn't a "normal" Yellowstone experience. At the time, only a handful of the park lodges were open and only 4 of the park's 12 campgrounds were open.
