Overview
Oregon Caves National Monument and Preserve is a very famous area established in the early 1900s that protects over 4,000 acres of old-growth forest and geological wonders. The highlight is the marble cave system formed over hundreds of thousands of years by acidic groundwater seeping through limestone.
Unlike lava tubes commonly found in Oregon, this is a rare marble cave, filled with underground rivers, stalactites, flowstone, and other fascinating formations. Above ground, the area is part of the Klamath-Siskiyou mountain range, making it just as beautiful above ground as it is below.
