Madison Campground has a good location in the somewhat center of the park. Of the other campgrounds available, I wouldn’t say it’s my favorite, but we made a last minute booking so I cannot complain too terribly much. The sites are pretty close to each other, and the bathrooms were pretty gross, but there was running water and at least one working sink in the loop we stayed in (some facilities were out of order). No showers, and a little more than I would have liked to pay given the experience, but we were able to sleep in the park and get back to exploring early the next day. I would reccomend looking into some of the other campgrounds in the park before settling with Madison.
