  - We checked it out in the Jeep and there were a few sites in the first loop that we could fit our rig, but none of the sites further down the road would work.

  - Unhook at the Flagg Ranch Information Station and then go check which sites are open and the road conditions as they could be rough after a storm.
  - There is no boondocking in Yellowstone.
West Yellowstone, MT: Buffalo Crossing RV Park
- NOTE: We drove through Yellowstone National Park from Colter Bay Campground to get to West Yellowstone.
  - If you launch open this map during the winter some of the roads through Yellowstone are closed so Google Maps changes the route to go around the park. That is not the route we took.

- Our only option due to limited availability in Yellowstone campgrounds for motorhomes our size
- Good Sam discount
