When we arrived at Buffalo Crossing RV Park, they were full. They did not have any information about our confirmed reservation. We showed them the print out. They said there was nothing they could do about it. This campground is nothing but a gravel lot. Luckily, Grizzly RV Park could accommodate us. I would have written this sooner, but I was going through cancer treatment.
Very nice campground. Well maintained, clean sites. Staff is very friendly and helpful. Restrooms and showers appeared clean. Laundry facilities are decent, $2 wash, 25 cents per 10mins of drying time. Took over 60mins to dry small loads. Need updated appliances. Wifi is lacking, but they warn you about it. Need to run hubs around the park. Sites are level and gravel. Best thing is that your less than 1 mile from Yellowstone entrance, get to the gate early or you'll be in traffic lines for a good 20mins or so.
Has all the necessities, Laundry, Showers, Restrooms, Water, Electricty., WiFi, Sewer hook up, Pet friendly, Very friendly staff, plus 2 free tickets to the Imax. As you can see everything is graveled but clean, no shade but we didn't spend much time there except to sleep. I would recomend it to any one. We will return next time we're in West Yellowstone.
