When to Visit:
The park is open all year round, and each season boasts its own reason to visit. Of course the park is undeniably beautiful in the summer, but be prepared for crowds. June-August are dry months, and although the weather becomes ideal for summer vacations, larger wildlife retreat to the backcountry to avoid the heat and tourists.
If wildlife is a must-see, try Yellowstone in the spring. Though April and May tend to cling to snow and colder temperatures, late May and June are much warmer—highs reaching 70°F. Be warned: May-June are the rainiest of months, but with annoyance comes a big payoff—wildlife.
Fall and winter both have their reasons for attendance. Autumn is a bit unpredictable; snow can sneak up as early as September. But it’s a great time to see the great aspen trees turn gold, as well as hear the elks sound off in the lands. Winter typically runs from late November to March and it remains snowy and cold. It may not sound ideal, but the winter is a great time to visit if you are seeking a new perspective of the land without the crowds. Read more about what winter in Yellowstone has to offer.

At over two million acres, it may already be apparent that you need a car. Unless you visit with a specific tour group, note that there is no public transportation within the park. Because you must rely on your own ride, the park has equipped most junctions with gas and diesel, as well as repair and towing services. The park has five entrances from every direction and its seven regions add up to 3,472 miles, so have a map handy at all times.
