The great Mount Lemmon is named after one of its first recorded conquerors: Sara Plummer Lemmon, a botanist who in 1881 became the first woman to reach its summit. Nowadays, you don’t have to be a pioneer to reach the 9,157-foot peak, but a daredevil streak doesn’t hurt. The Catalina Highway winds up, down and around Mount Lemmon, roller-coaster-style, coming to a halt in the little mountaintop town of Summerhaven. Gorgeous overlooks along the highway—with such curious names as Hoodoo at Windy Point, Sykes Knob and Inspiration Rock—afford mileslong views of the city and desert below.
