We stayed at this RV Park two nights. We were in Site 102 backed up to the train tracks. The noise really didn't bother us as we have a white noise machine.  Site somewhat level. Had to use blocks under front tires.  Very nice laundry facility. Cable included.  We drove to the Grand Canyon from here. Took about an hour to get there.  Must see! Downtown Williams is within walking distance and has lots of restaurants, shops and bars.  We also walked over to the Grand Canyon Brewery for beers and pizza one evening. Very unique, beautiful place as well. Only big Con for this park was a lot of rocks/gravel and my dogs had no where to do there business comfortably.  Also, sites are close to one another.  Would recommend though if you stopping in Williams!
