Fish creek campground was listed as “reservation only”. You could reserve on recreation.gov (terrible website) We stopped by around 7:30am - knew it was full but wanted to see what all the hype was about. Turns out they had 5 cancelations for that day - so we grabbed a spot at A16. Nice site - Privite on one side but unfortunately right next to a large RV but that’s not the parks fault now is it? The facilities were kinda bad - men’s bathroom had only one stall and one urinal? With over 20 sites in loop A? Hm. Showers were closed due to covid - a real bummer coming from Teton and Yellowstone where the showers are open. They did have a dump sink that I did appreciate. All in all we got a nice spot near the lake - quiet site - very good location (but also the only campground open in the park) would recommend if you are able to get a reservation online but certainly nothing to write home about.
