Oregon Caves National Monument
Deep within the Siskiyou Mountains are dark, twisting passages that await your discovery. Eons of acidic water seeping into marble rock created and decorated the wondrous “Marble Halls of Oregon.” Join a tour, get a taste of what caving is all about, and explore a mountain from the inside and out.

Oregon Caves National Monument Nestled deep inside the Siskiyou Mountains, the caves formed as rainwater from the ancient forest above dissolved the surrounding marble and created one of the world’s few marble caves. The highly complex geology found on the Monument contributes to the unusual and rare plants and animals found nowhere else but here. Experience the extensively decorated and adventurous “Marble Halls of Oregon.”
