Visitation to Yellowstone National Park in the days before, during, and after the solar eclipse on August 21 is anticipated to be heavier than usual.
On August 21, visitors will see the moon pass between the sun and earth, blocking a part of the sun – a partial eclipse – throughout the park. Yellowstone is not in the path of totality.
Park roads and facilities may be overwhelmed by this large influx of visitors who are here to see the eclipse. Yellowstone does not recommend traveling in and out of the South Entrance on August 21. That entrance borders Grand Teton National Park and the center-line of the solar eclipse will pass over that park, placing it in the path of totality. August 21 is anticipated to be the busiest day in the history of Grand Teton National Park.
In Yellowstone, the partial eclipse will occur between 10:15 a.m. and 1 p.m. The eclipse will “peak” around 11:36 a.m. for a little over two minutes.
