Hi, my wife and I are planning a trip to southern AZ in December. It's a 4 night stay, 2 nights in Cochise and 2 nights in Tucson. We are definitely going to Chiricahua NM and doing the Big Loop (which should take 5+hours), and we definitely want to check out Saguaro NP during a sunset.
Everything else is up for grabs, would you recommend Wasson Peak over Sabino Canyon? Is Kartchner Caverns a must see? Anything would help, thanks.
