Kartchner Caverns are beautiful limestone caverns that were originally discovered by Gary Tenen and Randy Tufts in 1974, known for their 2.4 miles of spectacular underground passageways. The caverns have been operated as a tourist attraction since 1998, open to the public for guided tours. Visitors can explore lovely sites such as the caverns' Throne Room, which is home to one of the world's longest soda straw stalactite formations, and the impressive Kubla Khan column. Other major features that can be explored as part of guided tours include the caverns' Mud Flats, Cul-de-Sac Passage, and Strawberry and Rotunda Rooms. Throughout the summer months, the caverns serve as an important nesting site for endangered Myotis velifer bats. Above ground at Kartchner Caverns State Park, visitors can hike picturesque nature trails such as the 4.2-mile Guindani Trail.
