Mount Lemmon

Mount Lemmon is in the Santa Catalina Mountains located in the Coronado National Forest north of Tucson, Arizona. At the peak of Mount Lemmon is an astronomical observatory. The Catalina Highway, also called the Mount Lemmon Highway, runs up the Santa Catalina Mountains from the east side of Tucson up to Summerhaven, at the top of Mt. Lemmon. The beautiful, curving road is a favorite drive for tourists, motorcyclists, and cyclists, and has been recently designated as the Sky Island Parkway. A dirt access road to the summit on the "back side" of Mount Lemmon offers a secondary route to the top.
