Another question. In planning I see some campgrounds around Yellowstone are first come first serve. Am I likely to have problems getting a site that way and is there a viable backup option if I get turned away? Thanks
Best way to get one of those first-come, first-served sites is to show up at the campground about 9:30 AM and wait. Kind of a hassle. You can make reservations at Yellowstone campgrounds, though if there are no sites showing available now for your timeframe, you may have to call back periodically to see if there are cancellations. You can also reserve a site at a West Yellowstone or Gardiner RV park (private, outside the park).
