Worst Time to Visit Yellowstone National Park – Avoid These Months

Millions of people go to Yellowstone every year, making it one of the busiest national parks in the United States. Yellowstone National Park spans the area of three states (Wyoming, Idaho, and Montana) covering over 2 million acres of breathtaking geological and geothermal phenomena. Many people go to Yellowstone to witness famous landmarks such as Mammoth Hot Springs, the Grand Canyon of Yellowstone, Old Faithful, and the Fishing Bridge.

Yellowstone National Park is a fantastic getaway for most of the year, but there are a few months out of the year that is considered the worst time to visit Yellowstone National Park. The park’s atmosphere and accessibility might be significantly altered by inclement weather.

The Worst Time to Go to Yellowstone National Park

The winter months, December to February, are the worst time to visit Yellowstone National Park, especially for the less daring tourists. The main reason is that temperatures drop far below freezing and the trails are blanketed in snow.

Due to the intense cold, animals follow their normal migratory patterns, and fewer paths are accessible for exploration, therefore fewer animals can be seen. Travelers should pack warm clothes and anticipate long delays due to road closures caused by bad weather if they plan to come during this period.

It also starts snowing early, towards the end of October on average, and the park’s sensitive ecosystems start to suffer from erosion caused by the freeze-thaw cycle. Because of the weather, going outside to take photos or explore is hazardous or impossible.

There will not be any working restrooms during the off-season, and there will only be a few ranger stations staffed. To some, it may seem like paradise; but, the cold here is unlike any other. Your “winter” coat will not keep you warm. Yellowstone National Park in northern Wyoming has harsh winters.

You will not be able to spend hours at a time hiking or touring outdoors. Looking out the vehicle window as you drive through Yellowstone will be one of your most memorable experiences there. The park will be closed and frozen over, and so will you.

Advice for Tourists: Yellowstone in the Winters

Due to the snow and ice, several of the roads leading to the park are blocked. It is also more challenging to discover the wildlife that attracts tourists at this time of year. So, if you are thinking of visiting Yellowstone in the winter, here are some things to think about.

Dangerous Roads

When visiting Yellowstone in the winter, you must take all necessary safety measures. It is not uncommon for snow and avalanche hazards to block the roads going into the park, making getting there a risky proposition.

If you must drive yourself, invest in all-weather tires and any additional equipment, such as chains or tire studs that will improve your vehicle’s grip on ice roads. In case of an emergency, you should also let someone know your exact whereabouts and anticipated return time.

Pack Accordingly

It is no secret that Yellowstone’s winters can be frigid; in fact, it is not uncommon for the mercury to drop below freezing. It is crucial to pack warm clothing in layers, including sweaters, down coats, caps, and gloves, in case you find yourself in such a climate.

Also, if you can, get a pair of waterproof boots to protect your feet from the heavy snow drifts and puddles you can see on milder days when the snow melts. To be toasty and comfortable during your journey, it is recommended that you pack a thermos with some hot tea or chocolate.

The weather in Yellowstone during the winter may change rapidly. This is the time of year when snowstorms and blizzards are common, so it is important to know what to do if you get stranded in the wilderness. This includes knowing where shelter is located along your route in case you need it and having a plan for what to do if you get lost.

Follow the right rules and regulations as well. Earlier, the baby bison issue at Yellowstone National Park sparked a debate on social media. It’s better to follow the guidelines and don’t interact with park animals.

Carry Extra Food and Equipment

Restaurants are operating in the park throughout the winter, but if you plan on venturing far from civilization, there is a chance of unavailability or shortage of food. It is better to pack your provisions in case you end yourself in a region far from civilization with no means of obtaining food or water.

Bring along enough food and drink to satisfy everyone who will be accompanying you on your journey. Extra provisions, water, batteries, lighting, a means to make a fire, a first aid kit, a whistle in case of an emergency, a compass or GPS, a map, and a guidebook are just a few examples of useful equipment.

Other Worst Times to Go to Yellowstone National Park

Other than the coldest months of the year, there are other seasons of the year that we consider the worst times to visit Yellowstone Park.

Early Spring

In March, the majority of the park’s services are unavailable. This month sees the change from winter accommodations to summer ones. The few lodges that are open throughout the winter close for a few months so that the roads can be plowed, and snowmobile traffic comes to a halt. Even in May, snowfall is common. Up to the first week of June, winter storms are still a possibility. Spring weather is often fickle, so it is best to be ready for everything.

The weather is also quite unpredictable, with fluctuating temperatures, occasional snowstorms, and muddy conditions due to snowmelt. Limited accessibility and reduced services may also be a factor.

Until late April, most park roads will remain blocked, and the park will be blanketed with snow. This is not the best time to come unless you plan on doing any winter sports like skiing or snowshoeing.

Opening months for most hotels are May and June. Staying in Gardiner or Cooke City outside the park and driving into the Mammoth or Lamar Valley regions is your only option if you want to visit in early to mid-April.

Rainstorms and Wildfires in Summer

Summers are another one of the worst times to visit Yellowstone because of abnormal weather. Storms are frequent and usually bring rain. Thunderstorms are common in the afternoon throughout the summer. Avoid the wet weather by beginning your explorations before daylight.

In addition to that, the wildfire season has been growing worse, unfortunately. Wildfires on the west coast (even as far west as California!) can have a significant impact on air quality and visibility, although this can vary widely from day to day. Notably, there have been several wildfires in this park in the past, which is why we recommend you avoid them.

Most Crowded and Expensive Months to Visit Yellowstone

The peak season for tourists to Yellowstone National Park is summer. Since schools have holidays for the summer, families from Texas and Florida are flocking to the dry, cool climate of Wyoming, Montana, and Idaho.

Crowds at renowned destinations like Old Faithful tend to peak between the middle of June and Labor Day. The first month with over 1 million views was July 2021. Because of the tremendous demand, hotels are best reserved well in advance. If you wish to stay in the park during the summer, for instance, you need to make your reservations roughly a year in advance.
