Best Time to Visit Grand Teton (And Worst)

When is the best time to visit the place where the buffalos roam, where the deer and the antelope play? They actually do in this national park, and you can see them right from the road. 

During my epic 5 month road trip through the Rockies, I went to this Grand Teton twice. First in March, where I shredded on the slopes of Jackson Hole. And then again in May, when I finally got to explore more of the park since a big chunk of it was closed the first time.

In terms of weather, Grand Teton National Park can swing from glorious summers to frosty winters. Here’s a snapshot of the visitor seasons at Grand Teton:

• Peak Season: Summer (June to August) 
• Shoulder Seasons: Late Spring (Late May/early June) and Autumn (September to early October) 
• Off-Peak Season: Winter (October to May)

Next, I’ll delve deeper into the seasonal nuances, highlight any special events, and provide a monthly climate breakdown. Whether you’re planning a day trip to Grand Teton or an extended stay, hiking the Inspiration Point, or taking on a wildlife safari, these are the best times to go to Grand Teton National Park.

Best Time to Visit Grand Teton National Park

Best Time of Year to Visit

The best time to visit Grand Teton National Park is during the summer months, from June to August. It’s when the park is filled with sunlight, the temperature is around a comfy 70 degrees, and the wildflowers are blooming in vibrant colors against the stunning Teton Range. 

The Jenny Lake boat rentals and shuttle only operate in the summer, and it is when all facilities will be open.

Best Time for Good Weather

Enjoy great weather during the summer months. It’s the only season where the park has pleasantly warm temperatures, usually reaching the upper 70s during the day and cooler evenings in the mid-40s.

Best Time for Smaller Crowds

If you prefer to avoid crowds, come in May or October. During these months, the park road will have just opened, but the number of visitors is less than half of what it is during the summer. But, some areas of the park may still be snowy during these times. 

For the absolute least crowded experience, come during winter when the number of visitors is at its lowest, with only 10% of the summer peak. However, many park facilities and roads are closed unless you are interested in winter activities.

Cheapest Time to Visit

This area is famous for summer and winter activities, including a world-class ski resort, so accommodation and tour prices remain relatively stable throughout the year. During late spring or fall, outside of major holidays and the peak summer season, you may be able to find more affordable accommodation options.

Best Time for Stargazing

For stargazing enthusiasts, the best time to visit is during the new moon phase in the summer months. The park’s International Dark Sky Park status ensures minimal light pollution, allowing millions of stars to shine brightly. Summer is the only season warm enough to enjoy this nighttime activity.

Worst Time to Visit Grand Teton

November to April are considered the least favorable time to visit Grand Teton National Park. This is primarily due to the harsh weather conditions, with temperatures often dropping below freezing. Many of the park’s roads and facilities are closed during this period, and outdoor activities are limited due to snow and ice.

Park Closures

Grand Teton National Park remains open year-round, operating 24/7. But, from November to May, most areas of the park are inaccessible by car due to seasonal closures. Visitor centers also shift their hours accordingly: during the summer, they are open from 8 am to 7 pm, while in the winter, it’s shortened to 5 pm.

Seasons at Grand Teton National Park

Spring (Late May/early June)

Spring in Grand Teton National Park often lingers on the chillier side, especially in early May. As the snowpack melts, the wildflowers, like the Indian Paintbrush and Lupine, start to bloom.

This season is particularly appealing as it’s prime time for animal sightings. Black and grizzly bears emerge from their winter hibernation, and herds of elk and bison graze in the meadows. 

Weather in the Rockies can be unpredictable, and spring snowstorms are not uncommon. The opening times for some park facilities and certain roads, like the Moose-Wilson Road and Jenny Lake Scenic Drive, are typically not fully open until late May or early June. 

Summer (June to August)

Summer is the undisputed champion in Grand Teton National Park. The warm and sunny days supply perfect conditions for outdoor adventures. 

Trails are all open and ready for hikers of every level. And if you’re a water baby, the warmer temperatures make it a perfect time for white water rafting or a serene float down the Snake River. 

However, it’s not all sunshine and rainbows. With the park at its busiest at over half a million visitors a month, expect the popular sites to be crowded and accommodation to be booked up quickly. 

Fall (September to November)

Fall in Grand Teton National Park dons a riotous array of fall foliage colors. The weather is pleasant – it’s cooler than the summer, but not yet the biting cold of winter, and the trails are less crowded.

Fall is the mating season for elks, and witnessing the ‘rut’, is an absolute must. It’s common to hear the elks’ haunting bugles echoing through the valleys.

Winter (December to April)

Winter in Grand Teton is a sparkling white paradise for those who love the cold and aren’t afraid of a little snow. Winter activities here are plentiful. Skiing, snowshoeing, and cross-country skiing are popular pastimes. You can also take a peaceful snow coach or sleigh ride on a winter wildlife safari.

Wildlife viewing is still possible in winter, but it requires a bit more patience and a keen eye. You may encounter moose foraging in the snow or spot a bald eagle soaring above. 

The park faces several road closures due to heavy snowfall. Also, visitor centers and other park facilities often operate on reduced hours.
