Oregon Caves National Monument & Preserve Dark Sky Park
A Celestial Sanctuary in the Siskiyou Mountains
Tucked away in the rugged Siskiyou Mountains, Oregon Caves National Monument & Preserve offers not only a journey beneath the Earth’s surface but also an unparalleled experience of the night sky. Recognized as an official International Dark Sky Park, this unique destination in the Sisikiyou Mountains provides visitors with breathtaking views of the cosmos, free from the intrusion of artificial light. Here, the sky comes alive with dazzling stars, planets, and celestial phenomena, making it a haven for stargazers, photographers, and nature enthusiasts alike.
Why Oregon Caves is a Dark Sky Park
Designated by the International Dark-Sky Association (IDA), Oregon Caves National Monument & Preserve meets strict standards for preserving natural darkness. This commitment to protecting the night sky ensures minimal light pollution, allowing visitors to experience a sky much like the one seen by early Indigenous peoples and settlers centuries ago. Through conservation efforts, sustainable lighting practices, and public education, the monument champions the importance of dark skies for wildlife, human health, and cultural heritage.

Stargazing at Oregon Caves
When night falls, the sky above Oregon Caves transforms. On clear evenings, visitors can spot the Milky Way stretching across the sky, observe meteor showers, and witness the glow of distant galaxies. The best stargazing opportunities occur during new moons, when the absence of moonlight enhances the visibility of countless stars.
Best Stargazing Locations
- Bigelow Lakes Area: A short hike from the monument, this serene location offers an unobstructed view of the night sky.
- Monument Headquarters: While slightly affected by minimal facility lighting, this area still provides an excellent view of constellations and planets.
- Bolan Peak Lookout: Offering a panoramic vantage point, this high-elevation site provides stunning, uninterrupted views of the night sky. After a cabin rehabilitation during summer of 2025 is complete, the iconic fire lookout with four walls of windows and a wrap-around deck will become rentable once again.
Dark Sky Programs & Events
To celebrate its dark sky status, Oregon Caves National Monument & Preserve hosts special night sky programs throughout the year. These events, led by park rangers and astronomy experts, include guided constellation tours, telescope viewings, and discussions on nocturnal wildlife. Visitors are encouraged to check the park’s calendar for upcoming events, including the popular annual Perseid Meteor Shower Viewing.
Plan Your Visit
While access to Oregon Caves National Monument & Preserve is free and open year-round (though may be limited during winter months due to snowfall), access to the caves is only available through ranger-guided tours which are offered seasonally.
- The best time to experience the dark skies: During the New Moon and the 10-day window bookending the New Moon when the moon is below the horizon for most of the night. Seasonally, late spring through early fall is best, when clear conditions and mild temperatures make for comfortable stargazing. Be sure to bring warm layers, as mountain nights can be chilly, even in summer.
- What to Bring: You can see many stars with your naked eyes, especially under a dark sky. Binoculars or a small telescope can make your trip even more extraordinary. Also, bring a red light flashlight or headlamp to avoid disturbing your night vision.
- Prepare for Limited Cell Phone Service: Connectivity can be spotty in the vast open spaces of the Illinois Valley. Ensure you have a physical map to guide your journey. Maps are readily available at the visitor center and here, providing detailed information to help you explore safely and get the most out of your visit.
