Oregon National Caves National Monument and Preserve

Nestled in the rugged beauty of the Siskiyou Mountains, Oregon Caves National Monument and Preserve offers a journey through time and space—both beneath the earth’s surface and under its dazzling night skies. Located in southern Oregon, this 4,554-acre sanctuary protects a labyrinth of marble caves and an expansive wilderness teeming with biodiversity, where endangered and endemic species flourish in old-growth forests. The Park’s unique ecosystem is a testament to the region’s rich geologic history, a saga of shifting mountains, evolving climates, and thriving life.

Now, Oregon Caves National Monument and Preserve (ORCA) celebrates a new milestone: recognition as an International Dark Sky Park by DarkSky International. This certification underscores the Park’s commitment to conserving its pristine night skies and preserving the nocturnal environment for generations to come. ORCA joins an exclusive network of only 128 Dark Sky Parks worldwide and stands as Oregon’s second such destination, following Prineville Reservoir State Park.

Amber Harrison, Program Manager for DarkSky International’s Dark Sky Places Program, hailed the achievement: “This designation highlights ORCA’s dedication to conservation, offering visitors an unparalleled blend of natural and celestial wonders while fostering community engagement and environmental stewardship.”

A Commitment to Night Sky Preservation

The dark skies over ORCA remain a sanctuary from the creeping glow of urban light pollution, thanks to the Park’s efforts to safeguard its nocturnal environment. Over the next decade, the Park will implement a three-phase lighting retrofit that adheres to DarkSky International’s Five Principles for Responsible Outdoor Lighting. By reducing artificial light and preserving natural darkness, ORCA ensures that its ecosystems and nightscapes retain their timeless character.

Buffer zones of undeveloped land around the Park further protect it from light trespass, creating a haven for stargazers and nocturnal wildlife alike. This initiative not only honors the ecological integrity of the region but also inspires educational outreach and scientific collaboration. From community programs to global partnerships, ORCA shines as a beacon of what’s possible when nature and human effort align.

A Legacy of Exploration and Wonder

Established in 1909 to protect its stunning marble cave systems, ORCA has long been a destination for discovery and recreation. Today, visitors can explore its fascinating caves, hike scenic trails, and marvel at the wildlife thriving in its old-growth forests. The addition of the International Dark Sky Park certification enhances the Park’s appeal, offering opportunities to witness some of the clearest night skies in the region.

Seasonal events, including guided cave tours and summer stargazing programs, invite visitors to connect deeply with the natural and celestial wonders of the Park. Star parties in ORCA’s Historic District and other nighttime activities bring the cosmos to life, fostering an appreciation for the beauty and significance of unspoiled night skies.

A Bright Future for Dark Skies

The recognition of ORCA as a Dark Sky Park is a testament to the tireless work of Park staff, volunteers, and collaborators like DarkSky Oregon. Their efforts ensure that the star-filled skies above the Siskiyou Mountains remain a source of inspiration and wonder, free from the encroaching haze of artificial light.

Whether you’re a curious explorer, an avid stargazer, or a wildlife enthusiast, Oregon Caves National Monument and Preserve offers a rare chance to step back in time—both to the geologic past beneath the earth and to a night sky as our ancestors saw it. Plan your visit and experience the magic of one of Oregon’s most extraordinary treasures.
