The Catalina Highway provides the only paved access to attractions on Mount Lemmon and the Santa Catalina Mountains, and has become a popular destination for tourism in the region. According to the Federal Highway Administration, the Catalina Highway is traveled over by more than one million visitors every year. Among the many recreational opportunities in the Coronado National Forest, through which the highway travels, are numerous campgrounds and picnic sites, multi-use trails, and scenic views. The Mount Lemmon Ski Valley, located at the summit of the highway, operates a ski slope during the winter months and remains open during the summer, offering summer "sky rides" on the ski lift. It is billed as the southernmost ski resort in the continental United States.
