The Best Time to Visit Grand Teton National Park

The best time to visit Grand Teton National Park is between Mid-May and late-September, when all of the park’s visitor centers, hiking trails, and roads are open and accessible to the public. 

During the summer, beginning in mid-June, most of the entire park is accessible. It’s the best time to enjoy hiking, fishing, boating, river rafting, camping and more without restrictions.

This is why summer is considered the best time to visit by many people. But the park WILL be crowded.

In contrast, winter and spring, between November and April, the harsh Wyoming winter rolls into the area and forces many roads and facilities to either shut down for the season, or have reduced hours of operation, as a result of high levels of snowfall.

If you plan to visit the park during the winter, be sure to check alerts and current conditions for the most up to date information on the weather conditions and closures. 

Park Hours

Grand Teton National Park is open year-round, 24 hours a day.

The visitor centers in the park each have their own operating hours and can provide information about the park.
