Kartchner Caverns State Park
Kartchner Caverns State Park is home to one of the great natural wonders of the American west. There is no known record of the huge living cave being seen before the 1970s and the pristine conditions within have been carefully preserved. A remarkable feature of this cave is that it's a 'wet' or 'living' cave; the calcite formations are still growing and display a stunning variety of multicoloured cave formations. Two different tours of the caves are available and there is a visitor's centre which details the history and geology of the caverns with interesting exhibits. Tours take between 90 minutes and two hours. Photography is not allowed in the caves but there are postcards available.
