Best Time to Visit Yellowstone National Park

Yellowstone National Park is worth a visit no matter the time of year. It's the first national park in U.S. history, established in 1872, and encompasses the supervolcano known as the Yellowstone Caldera. This dynamic landscape is home to one of the largest collections of hydrothermal features in the world. And this collection of geysers, fumaroles, and mud pots draws over four million visitors every year.

The best time to go to Yellowstone National Park depends on the desired experience. The summer months bring beautiful 70-degree weather and extended daylight hours. Half of the park's annual visits also occur during these months. Summer visitors should expect crowded boardwalks, backed-up traffic, and difficulty with finding lodging.

The shoulder seasons offer some respite from the crowds, making the fall and spring an excellent time to travel to Yellowstone. Visitors will want to pack warm clothes in the shoulder seasons and a rain jacket for the spring. But the new colors in the park are well worth the travel. Between wildflowers blooming in the spring and the crisp air of autumn, spring and fall are beautiful seasons to go to Yellowstone.

Winter also offers a magical time of year to visit Yellowstone. The park's many fumaroles, hot springs, and geysers are true natural beauties when covered with snow. Although, freezing winter temperatures and few operating facilities deter some visitors to Yellowstone in the winter. For these reasons, winter is one of the best times to visit Yellowstone National Park to avoid the crowds.

Make no mistake, Yellowstone is a special place to visit any time of year. But spring and fall are the best times to go to Yellowstone thanks to fewer crowds and comfortable weather. Specifically, the months of May and September cater to great visitor experiences.

Road closures in Yellowstone begin in late October, and many roadways remain closed until April or May. The time between these road closures and Memorial Day and Labor Day are great windows for visiting. Colder temperatures and rain or snow are present during early spring and late fall.

Despite the crowds, the summer is also a great time of year to visit Yellowstone. With near perfect 70-degree weather throughout the day, summer also lines up with many vacation schedules to make for a busy park. Arriving early to the park or exploring some longer trails can help navigate the growing crowds of Yellowstone during the summer.

If you had to narrow down the best month to visit Yellowstone, though, it would have to be September. Crowds thin out after Labor Day in Yellowstone (the first Monday in September), and temperatures remain in the 60s, and autumn foliage gives some fantastic color to the park.

All roads typically remain open in Yellowstone National Park throughout September. Popular lodges like the Old Faithful Inn and Mammoth Hot Springs Hotel also accept reservations throughout the month. Crowds still exist during September, but dropping temperatures and school schedules lead to a decline in visitors by the end of the month.

But no month is a bad month to visit. Steaming features like Steamboat Geyser, Grand Prismatic Spring, and Black Growler are active throughout the year. However, many avoid Yellowstone in the winter months thanks to below-freezing temperatures and unplowed park roads.

Spring (April - May): Every road in Yellowstone National Park is typically accessible by the end of May. A few prominent roadways open as early as April. Rain and mud are common in spring, but with far fewer crowds and full accessibility of the park, spring is a great season to travel to Yellowstone.

Wildflowers bloom throughout the park beginning as early as April, and the open meadows of the park really gain some color in May. Bison calves are also spotted within their herds during the spring, as well as many other animals that become more active as temperatures warm up. Visitors should pack for the weather, including a rain jacket, as well as shoes that can handle a little mud.

Summer (June - August): The summer brings fantastic weather to Yellowstone and extended daylight hours. Every facility and roadway within the park operates throughout the summer. Many of the towns and communities surrounding Yellowstone also host celebrated weekend events.

Between these three months of summer, Yellowstone receives upwards of two million visitors. Resources like lodging and campgrounds are something to plan for in summer.

Fall (September - October): Roads in the park remain open throughout September and October. And many lodges still accept guests into November. Fall is still a popular time to go, but crowds tend to thin out after Labor Day. Logistics like parking and lodging are easier to navigate in September and October.

Wildlife is still active this time of year as the animals prepare for a long winter. Yellowstone shines with fall colors from approximately the last week of September through the first week of October. Snow is a possibility in October and dropping temperatures dip well below freezing throughout the night.

Winter (November - March): With freezing temperatures, less-active wildlife, and snow-covered trails, winter is the least popular time to travel to Yellowstone National Park. For those that like to avoid crowds, this is what makes winter the best time to visit Yellowstone. Alongside fewer crowds, the scenic beauty of a geyser steaming next to a snowbank is inspiration enough for repeat winter visits.

The summer offers the best weather in Yellowstone. The season encompasses 70-degree daytime temperatures, extended daylight hours, and pleasurable weather to sleep at night.

The months of July through September are also some of the driest months in Yellowstone. Nighttime temperatures are also comfortable for enjoying sunsets and starry nights. And much of the park's wildlife is spotted enjoying the nice weather this time of year.

A major appeal of the entire Yellowstone ecosystem is the diverse amount of wildlife the habitat supports. Wildlife sightings in Yellowstone include bison, mule deer, elk, and bighorn sheep. Both black and grizzly bears also live in the park.

Wolves have made a dramatic resurgence in Yellowstone, and the winter is the best time to see these stealthy creatures. Wolves are easier to spot in the winter, especially with binoculars, thanks to the stark white backdrops of a snowy landscape.

Bison calving typically occurs in mid-April in Yellowstone. Bears tend to be more active this same time of year following winter hibernation. The summer is a great time to spot big animals like moose and elk. Resident bison herds sometimes block traffic throughout the season.

Dawn and dusk tend to be one of the best times for wildlife viewing in Yellowstone National Park. It's extremely important for the safety of the visitor, and the safety of the animals, to never feed, approach, or otherwise interact with wildlife at Yellowstone.

Best Time to Visit Yellowstone National Park for Fall Colors

In a typical season, the best time to go to Yellowstone for fall colors is from the last week of September to the first week of October. Variable weather conditions adjust these dates, but if you aim for this time in autumn, the chances of seeing fall colors are high. Park roads typically remain open until the second week of October.

Some of the best areas for fall colors in the park include the Lamar Valley and Mammoth Hot Springs. Hikers and backpackers go the distance on hiking trails throughout the Lamar Valley to indulge in the changing scenery. Visitors in the fall should plan for below-freezing temperatures throughout the night.

The winter is the best time to go to Yellowstone National Park to avoid the crowds. The snowy landscapes and road closures keep winter visitors to a minimum. The only road in the park that is open year-round is from the Gardiner, Montana entrance down to Mammoth Hot Springs. Beginning in January, other roads in the park are only navigable by cross-country skis, snowshoe, stagecoach, or snowmobile.

To enjoy the full accessibility of the park with fewer crowds, spring and fall are the best months to go. Larger crowds gather in the weeks before Memorial Day in May and began to thin after Labor Day in September. The weather this time of year has variable conditions with more rain in the spring than in the fall.

The beautiful weather and idyllic conditions contribute to Yellowstone National Park's two-million-plus visitors in the summer. When traveling during this peak summer season, arriving early to trailheads makes a big difference. Checking out popular areas in the evening can also help beat daytime crowds.

Best Time to Visit Yellowstone National Park for Photography

While every season provides stunning photographs, the shoulder seasons, between April and May and September and October, are the best times to visit Yellowstone for photography. These seasons provide fewer crowds in the viewfinder and plenty of lush scenery with less snow. Nearly the entire park is still open during these times of the year, including campground and lodging options, making it easier to capture sunset and sunrise shots. Fall colors are also a favorite with photographers.

The summer season is also a good time to visit Yellowstone for photography. The park is fully abuzz with wildlife, foliage, and daylight. Crowds this time of year are something to contend with, especially if trying to photograph prominent attractions like Old Faithful or Grand Prismatic Spring. Either try to incorporate crowds into the shot, or consider visiting these destinations at the break of dawn.

Winter provides a captivating time to visit Yellowstone. Much of the park sits under snow, except the several geysers, fumaroles, and other hydrothermal attractions. This combination of hot water and glistening snow offers rewarding shots for photographers willing to brave the elements.

How Many Days You Need to Visit Yellowstone National Park

With the distance required to travel to Yellowstone National Park and a total land area that's twice the size of Rhode Island, Yellowstone is never completely experienced in a single trip. Visitors should plan for at least two days minimum to explore Yellowstone National Park.

Not including travel time to the park, two days allows for enough time to see iconic attractions like Old Faithful, the Grand Canyon of the Yellowstone, and Grand Prismatic Spring. The Grand Loop Road in Yellowstone, a figure-eight loop that encompasses 142 miles at the heart of the park, is far too scenic to drive in a day.

However, two days only makes a small dent in the Yellowstone landscape. Numerous stops line the Grand Loop Road, as well as impromptu wildlife viewing opportunities. Five days is an optimal vacation length at Yellowstone. Five days gives enough time to make plenty of roadside stops and discover new points of interest. Five days also allow some flexibility in the schedule to account for weather.

Depending on where you are traveling from, winter and spring tend to be the most affordable time to travel to Yellowstone National Park. Limited park facilities are available in the winter, but the surrounding communities offer a real deal on lodging. Places like Cody, Gardiner, and Jackson offer special rates for winter visitors.

Early spring is also historically a cheaper time to visit Yellowstone. Roads in the park begin to open by mid-April, and all roads are typically accessible by Memorial Day. Alongside the park thawing from winter temperatures, park facilities, and local businesses also begin full operations. Visitors can expect lodging and airfare rates to climb beginning Memorial Day Weekend and throughout the rest of summer.
