After reading all of the wonderful reviews, I was a little underwhelmed. Perhaps it is because we arrived after a rainy period. Many of the sites in the A Loop were flooded or muddy and there was only one site occupied. B Loop was a bit better and there were a few more people there. Some sites in the A Loop overlook the river valley through trees but they are directly over railroad tracks so you will hear loud trains. No flush toilets but for pits (A Loop has sinks and a shower), reasonably clean. However I would not choose sites closeby because the fans are quite loud. Bison viewing road was cool and leads to the rebuilt granary (all that remains from a mill). Waterfall (across the street and about a mile from campground) is nice. Unless you hike the Minnesota River Bluff trail, you could easily see the bison, granary, and waterfalls in half a day, making this good for just a one night stay.
