Oregon Caves Centennial Celebration 1909-2009
Cave tours are seasonal and are offered late March through the end of November.
We have several hiking trails that weave in and out of the old-growth forest on the monument. You can see vast views, waterfalls, and widest girthed Douglas fir tree known to exist in Oregon.

Climate
The Monument is located at an elevation of 4,000 feet (1,220 meters) on the wooded slopes of the Siskiyou Mountains, part of the coastal mountain range of Oregon and California. When you visit, expect comfortable summer temperatures, snowy winters, and rain during spring and fall.
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.
