Things To Do


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. Interestingly, there is a snail that lives on the marble rock outcrops of Oregon Caves that has adapted to use the calcium from the rock to make its shell. The Monument's ancient remnant old-growth coniferous forests contain endemic Port Orford Cedar and a Douglas-fir tree with the widest known girth in Oregon. Oregon Caves National Monument is small in size, 480 acres, but harbors a fantastic array of plants.
