Patience is a must. Long lines, very slow rubber-neckers who stop traffic for even the most common wildlife. Weekdays or very early/very late season is a must if you don´t want to feel like part of a barely moving caravan.
Simply Spectacular sights of Yellowstone National Park, Lakes, Forests, Geysers, Waterfalls and possibilities to see lots of wildlife. This excellent loop is like a holiday all on its own.
