When you make a reservation at Canyon, you do so for a site which is then assigned to you by park staff. You are not told of your site number until 11 am of the day you are to arrive. It was explained to us that this is to prevent people from pushing out those in the site you wish to occupy too early. This campground is HUGE (275 sites in 10 loops)! Since we were assigned to Loop A, we never saw how big it actually was. We had a pleasant stay here for one night (could only make a reservation for one night ANY of the park campgrounds back in March). The bathrooms were clean. Every loop except ours had a dishwashing sink; we were instructed to walk to another loop by the person who checked us in but once in our loop, there was a sign telling us to dump dishwater in the toilet. Since I use very little water when washing dishes, this worked out fine. The one thing that this campground had that differs from every other national park campground we’ve been in is that they have showers (one per person) and laundry facilities. We wanted to get an early start the next morning, so we did not take advantage of either service, but it was good to know. What I appreciated most was the recycling program that included just about everything (except 3-7 plastics), including small propane canisters.
