A trip to Yellowstone National Park must be planned 6-12 months in advance. Hotels, motels, campsites, resorts, and car rentals all book months in advance. Consider visiting after the snow melts or before it falls. Better yet, consider visiting in winter.

In keeping with environmental concerns the infrastructure cannot keep up with the amount of visitors the park receives each year. Be prepared for large crowds and slow moving traffic. The park is enormous so careful planning of how you will spend your time is crucial. Be certain to schedule a trip to the Grand Tetons which is located just south of the park.
