Off-trail tours are only offered between June and September and must be reserved in advance, with space limited to 8 per tour. See the Oregon Caves information page to make a reservation. The three-hour off-trail tour provides an introduction to caving and visits areas not seen on the general cave tour. Visitors will have to scramble over boulders, squeeze through tight spaces, and will have only a headlamp for illumination. All equipment is provided by the park service.
Built in 1924, this visitor center is adjacent to the Chateau and offers exhibits about the cave and items for sale. Cave tour reservations must be made at the desk, and cave tours start from the visitor center.
The center provides information about the area, including up to the moment cave tour information at the Oregon Caves National Monument. Same day tickets for cave tours are available at the center Memorial Day Weekend through Labor Day. Afternoon wait times can be long in the summer. Buying tickets before driving to the park can save a lot of time and hassle. (Reservations can be bought up to one day in advance of the day of visit on Recreation.gov.)
