A grouse hunter stumbled on this remarkable cave in 1907. It has been opened to the public since 1947. The US Forest Service offers a tour through a wondrous half-mile of stalactites and stalagmites from Memorial Day (weather permitting) through Labor Day. This is the largest developed limestone cave in Idaho. There is no handicap access, and the site tour does include climbing stairs. This tour is not advisable for people with heart or respiratory conditions. Sweaters and shoes with a good tread are advised. Maximum per group is 30. Arrive early in the day. An entrance fee is charged.
