Experience Oregon Caves National Monument
Deep inside the Siskiyou mountains lies the “Marble Halls of Oregon.” The caves formed when acidic rainwater dissolved the surrounding marble, creating one of the few marble caves in the world. The Monument’s ancient forests contain endemic Port Orford Cedar and one of the largest Douglas-fir trees in Oregon.
Explore the marble halls of Oregon Caves
Cave tours are seasonal and are offered late March through the end of November.
Tours are considered moderately strenuous. For their safety, children must be 42 inches tall to go on the cave tour. For more information, please visit Accessibility.
We have several hiking trails that weave in and out of the ancient forests on the Monument. You can see vast views, waterfalls, and one of the largest Douglas-fir tree known to exist in Oregon. You also might see some of the native wildlife found in the forest such deer, bats, cougars, black bears, and the elusive relic species of mountain beavers, Aplodontia rufa.
Food and Lodging
Dining services, gift gallery and lodging are available from early May through mid-October at the Oregon Caves Chateau. The Chateau opened in 1934 and is now a National Historic Landmark.
The Monument is located at an elevation of 4,000 feet (1,220 meters) and nestled in the wooded slopes of the Siskiyou Mountains. The Siskiyou Mountains are part of the coastal mountain range of Oregon and California. When you visit, expect comfortable summer temperatures, snowy winters, and rain during the spring and fall.
