Yosemite National Park to Close Due to Significant Smoke Impacts and Hazardous Air Quality

Yosemite National Park – Yosemite National Park announces that the park will close to all visitors and vehicular access due to significant smoke impacts and hazardous air quality throughout the park. All park entrance stations and roads will close beginning at 5:00 pm tonight, Thursday, September 17, 2020.

With air quality projected to be in the unhealthy to hazardous range over the next several days, the park anticipates the closure to be in effect at least throughout the weekend. The park will continue to assess the smoke impacts, air quality index, and fire activity throughout the region.  Yosemite National Park will reopen to visitors when conditions improve, and it is safe for visitors and employees to be in Yosemite National Park.

Yosemite National Park’s closure is in alignment with the closure of Sequoia and Kings Canyon National Parks and the surrounding national forests.
