More Info

  • Viewing is best on clear nights. “Dark Moon” weekends provide the most optimal viewing opportunities.
  • If you’re an amateur astronomer, you are welcome to bring your own telescope or binoculars.
  • There is a free but primitive Forest Service campground located near the observatory. Campsites are available on a first come, first served basis, although it rarely gets full.
