Grand Canyon Conservancy (GCC) recently spent $1 million converting all light fixtures to be dark sky-friendly, which should give Grand Canyon’s five million annual visitors a great view. It’s now officially an International Dark Sky Park. Although it’s the South Rim’s populated area that’s been made dark sky-friendly, for really great views head to the remote Desert View or Lipan Point.

Where the Great Plains meets the Badlands meets the Milky Way. More than 30 miles from the nearest large city, Theodore Roosevelt National Park’s northern section in particular is very dark. The Dakota Nights Astronomy Festival is held from Aug. 30 through Sept. 1, 2019 for an even better experience.
