A hunter, Elijah Davidson, is credited with finding the cave in the fall of 1874. President Taft made it a 480-acre national monument on July 12, 1909, and Congress added the surrounding preserve in December 2014. Entry to the monument is free. You pay only for a tour.

The parking lot is 20 miles from Cave Junction, and the drive takes about 50 minutes. The last 8 miles are narrow, steep, and full of blind curves, and deer are common. The park discourages large RVs and trailers past Grayback Campground (more on Grayback). It also warns against trusting GPS from the east: map apps can route you through Williams onto gravel roads. From the lot it is a 900-foot walk to the visitor center.
