Located on Tucson's east side is the Rincon Mountain Wilderness Area of Coronado National Forest. The most popular way to experience the Rincons is at Saguaro National Park East, which offers numerous trails, and Colossal Cave Mountain Park, a massive underground labyrinth and one of the largest dry caves in the world. https://www.visittucson.org/things-to-do/hiking/rincon

Located on Tucson's north side, the rugged Santa Catalina Mountains in Coronado National Forest are Tucson's most prominent range with the highest average elevation. The highest point is Mt. Lemmon at 9,147 feet, noted as the southernmost ski destination in the United States. A trip from the Tucson valley to Mt. Lemmon takes you from 2,000 to about 9,000 feet, with scenery that resembles a trip from the Mexican to the Canadian border. https://www.visittucson.org/things-to-do/hiking/santa-catalina
