I was able to book this campground for the same day online. I know it was just luck that they had a site open, but it is one of the campgrounds that takes reservations inside the park. The campsites themselves are a bit too close for my liking. I prefer a little space, maybe some trees between sites, but these were just stacked side by side, back to back. The shower/laundry/office area was nice. It is convenient to all the other amenities at Fishing Bridge including restaurant, gift shop, gas. I wanted this location due to the grizzly sightings at nearby Yellowstone Lake. It was the closest campground to that area.
