Special Volunteer Events
Join us for one of our annual volunteer events when we provide a real service to Oregon Caves by picking lint and bits of trash along the cave tour path! No experience is necessary to participate, just a desire to restore the cave and ability to perform light physical work. Advance registration is required, as these events can fill up.

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.
