Cave Tours Closed for Season
Cave Tours are closed for the winter. Tours will resume April 26, 2014. All trails on the monument remain open.
Due to recent road work on Hwy 46 and steady rain, the road is muddy in spots. Exercise extreme caution while driving to and from the Monument.
We are experiencing technical difficulties with the cameras.
These images are not up to date and we hope to have this issue fixed shortly.
Did You Know?
Carbon dioxide mixes with water that condenses on the wall of the cave to create a very weak acid. Over long periods of time this "acid dew" eats away at the marble walls of Oregon Caves making the cave larger.
