Lava River Cave was at one time a major lava conduit. The cave features over a mile of impressively tall and broad passages. Look for interesting flow features on the floor and frozen lava drips, or "lavacicles", on the shiny linings that coat walls and ceilings like the glazed surface of pottery.

It is located in the Newberry Volcanic National Monument within the Deschutes National Forest.

Stop by the U.S. Forest Service Visitor Center at the turn-off to Lava River Cave on U.S. Route 97 to learn more about the cave and its environment, and to rent a lantern for the self-guided cave tour. Bring an alternate source of light, in addition, and carry a sweater or jacket. The cave , maintains a temperature close to 41 degrees F year round.

Inquire at the Visitor Center about visitation guidelines for other caves in the park, including Skeleton Cave, Charcoal Cave, and Lavacicle Cave.

Unlike most show caves, the Oregon Caves are formed in marble, or limestone that has been cooked and crumpled deep beneath the Earth's surface. The marble has since been uplifted and fractured, allowing for the development of cave passages where water charged with weak carbonic acid from the soil flowed along zones of weakness in the rock. The Oregon Caves are very well-decorated with a variety of dripstone formations, many of which are still activiely growing.

The guided cave tour lasts about 75 minutes and covers 0.6 miles of passageway, including 550 stairs. An additional 0.3 miles on the surface, some covering steep terrain, completes the loop tour. Bring a light jacket, as the cave varies between 38 and 45 degrees F. The tour is not recommended for anyone with heart, breathing, or walking difficulty. Canes, crutches and tripods are not allowed in the cave. Children under six are not permitted in the cave unless they pass a height and physical ability test. The concessionaire does not provide child care services during the tour.

Above ground, visitors can enjoy the ecologically diverse transition zone between mixed and evergreen forests along several nature trails, many of which connect to trails in the adjoining Siskiyou National Forest.
