Half the park is after dark! From animals to plants and water to volcanoes, Lassen Volcanic National Park protects many different natural phenomena. One of the most spectacular is frequently overlooked -- our incredible, dark, night sky. Lassen Volcanic is one of the best places to learn about and enjoy the splendor of the night sky. Far from the light pollution of civilization, Lassen is one of the last sanctuaries of natural darkness. Whether you have yet to experience the grandeur of the Milky Way, or you are a dedicated amateur astronomer, Lassen's dark skies offer unparalleled view of the celestial wonders. Experience Lassen after dark:

  • Attend a Starry Night ranger-led program at various locations throughout the park
  • Join us for Lassen's Dark Sky Festival
  • Pick-up a night sky viewing book or sky chart from the Lassen Association bookstore, and explore the night skies on your own
  • Learn more about Night Skies online
  • New! Watch Lassen's Dark Sky video
