Created by Presidential proclamation in 1909, Oregon
Caves National Monument is small in size, 480 acres,
but rich in diversity. Above ground, the monument
encompasses a remnant old-growth coniferous forest
including a Douglas-fir tree with the widest known
girth in Oregon. Three hiking trails access this
forest. Below ground is a marble cave created by
natural forces over hundreds of thousands of years in
one of the world's most diverse geologic realms. The
cave is home to one of the largest exposures of
ultramafic rock in North America and one of the
largest, most pristine, and most complete segment of
old oceanic crust in Western America. The Monument is
one of the most biologically and geologically diverse
caves in the world. -nps.gov

A Tour through Oregon Caves is an adventure in geology. A myriad of calcite formations decorate the cave. You will find striking parachute-like flowstone at Paradise Lost and what appear to be giant ribs as you squeeze through the Passageway of the Whale. Tiny rimstone dams resemble miniature waves on the sea. It is the drip, drip, drip of water that decorates the cave, building the bizarre and erie sculptures.

Touring Oregon Caves has been a tradition for more than a century. Today, tours are conducted by The National Park Service. Guides lead you through a one-half mile marble passage and discuss the cave's natural and cultural history and it's preservation. Tours are scheduled regularly in spring, summer, and fall. In winter they may not be available due to heavy snowfall. A fee is charged and prices are subject to change. Tours last about 90 minutes. Waiting times can reach 90 minutes in the summer. To go on the regular cave tour, a child must be 6 years old, or at least 42 inches tall.
