The unique geology and climate of the region surrounding Oregon Caves National Monument provide a rich di- versity of plants, animal life and rock formations to see along several hiking trails and along the road to the Oregon Caves. There are regular guided tours of the caves from spring to fall. There is plenty to see and do for people of all ages and interests in and around the monument of natural and historical significance. Magnificent columns rise in Miller’s Chapel, one of many striking rooms within Oregon Caves. (Photo provided by National Park Service) 12 Southwestern Oregon’s Illinois Valley
