MAMMOTH HOT SPRINGS, WY – Next week on August 21, a partial solar eclipse will turn day to night for a few short minutes. If you plan to visit the park before, during, and after the eclipse, develop a plan, and keep the following facts in mind.
Yellowstone National Park is not in the path of totality, but Grand Teton National Park is. Yellowstone does not recommend traveling in or out of the South Entrance on August 21. That entrance borders Grand Teton National Park where the center-line of the solar eclipse will pass. August 21 is anticipated to be the busiest day in the history of Grand Teton National Park.

Watch for park staff at popular attractions, entrances and congested road junctions who will provide visitor information and manage traffic.
Expect temporary entrance or road closures if the park experiences gridlock.
Access restrooms at all visitor centers and most picnic areas.

Green & Clean
Consider packing out your recyclables and trash on eclipse day.
Discard trash and recyclables in bear-resistant trash and recycle containers if you leave them in the park.
Keep the air clean. Do not idle your car.
Get required Aquatic Invasive Species inspection and appropriate permits if you intend to watch the eclipse on park waters.
Bring appropriate eclipse viewing glasses (available in park general stores and bookstores) and solar filters for cameras, binoculars, or telescopes.
