Thursday through Saturday, September 14-16, 2023

Dark skies are beautiful and scientifically valuable. Humans have been contemplating their meaning for centuries. The National Park Service and its partner organizations invite you to discover the night sky through a series of astronomy programs. Every year, AstroFest provides the opportunity for visitors to experience this threatened resource, and learn about how important it is to protect. Come celebrate with us!

This year will highlight the night skies along the Gunnison River corridor, in three separate public land areas:

  • Thursday, September 14 events will take place in the town of Montrose, Colorado, in cooperation with the Bureau of Land Management and Gunnison Gorge National Conservation Area.
  • Friday, September 15 events will be at the South Rim of Black Canyon of the Gunnison National Park.
  • Saturday, September 16 events will be held at the Elk Creek district of Curecanti National Recreation Area.
