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.
• Be sure to bring warm clothes. At 6,300 feet the temperatures can drop below freezing even during the summer. Also, wear shoes appropriate for mountain terrain and bring a small flashlight with a red colored shield as well.
