Protecting the Night Sky

Creating a magical evening experience

The night sky over Grand Canyon reveals a cascade of luminous stars and planets. These ancient constellations have shaped the arts, sciences, and ideas across the millennia. The night sky is inspiring. It is primordial. It is also imperiled.

Grand Canyon National Park is one of the last places in the United States where one can experience a star-filled night sky. One-third of the world's population - including 80% of Americans - can no longer see the Milky Way.  

Grand Canyon National Park is seeking International Dark Sky Park status and is replacing light fixtures and bulbs throughout the million plus acre park to minimize light pollution and provide a pristine view of our galaxy.  

What's been completed

  • All of the park's 4,740 lighting fixtures have been inventoried and catalogued. 3,500 of these do not meet dark sky guidelines.
  • Light fixtures and very-low-lumen LED bulbs have been tested for a wide variety of installations.


What's planned

  • To achieve designation as an International Dark Sky Park, 1,500 fixtures will need to be replaced by 2019, the Centennial year of Grand Canyon.
  • Expanded Evening Programs and new night sky viewing areas are being developed.

Improvements and projects in Grand Canyon National Park are only possible because of the generous support from people like you.

Current Priorities

Dark Sky Preservation

Grand Canyon has some of the most pristine night skies on the planet. We're working to keep it that way. 

Desert View Inter-tribal Heritage Site

Members of American Indian tribes are working with the park to celebrate the tribal heritage of Grand Canyon. 

Trails Forever

More than 400 miles of historic backcountry trails lead into the canyon. We want to ensure that they remain welcoming and accessible.
