Road access within the Park is good during the summer months. There are several loop roads that connect the popular park attractions. There are 465 miles of roads within the Yellowstone Park, and 310 miles are paved.

While Yellowstone can be crowded during the summer, most of the people are on the roads and in the “front country” around the developed sites. If you want to experience the backcountry and get away from the crowds, their are over 950 miles of trails and 287 backcountry campsites.


Elevations within the park range from a low of 5,282 feet at Reese Creek to an upper elevation of 11,358 feet on Eagle Peak. Due to the high elevation of the Yellowstone Plateau, and the range of elevations, the temperature extremes throughout the year can be dramatic. On average, January is the coldest month with an average temperature of 9 degrees F. July is the warmest month with an average of 80 degrees F. Both the low and high temperature extremes were recorded in the 1930’s. The record low was -66 degrees F and the record high was 98 degrees F.
