Santa Catalina Mountains looming above Tucson — Coronado National Forest. Sonoran Desert at the base, transitioning up through chaparral, pine-oak woodland, ponderosa pine, and Douglas fir at Mt Lemmon\u2019s summit. Summerhaven for access. Monsoon season (July-September) produces king boletes, chanterelles, and lobsters up high; summer drive from Tucson saves 30°F.
