I would say dont bother stopping! We made reservations despite some of the review we had read, it was a big mistake. They would of had to lift the power lines for us to gain access which they have a pole to do. They would of had to lift for us to exit the spot was too small for our motorhome although we had given the the length and there would of been no way to get level. The power poles are an outlet mounted on a tree trunk! My advise just skip it!
I have to say this a a great little campground right on the Madison River. Kelly is great! We arrived without notice on a holiday weekend and he found a spot for us. Having driven around for a while looking for a place with reasonable prices and power and water this was it! We looked in West Yellowstone and $75.00 a night plus 7% lodging tax for being no where near the river was more that we wanted to pay! Slide on Inn here and enjoy your stay like we did.
