The iconic saguaro cactus — which can live 200 years and grow 40 feet tall — defines the Sonoran Desert landscape.
November–April: highs in the 60s–70s°F. Saguaros bloom in May–June, and summer is for sunrise hikes only.
Winter “snowbird” season is busiest; summer is quiet.
Summer highs exceed 105°F, and July–September monsoon storms bring flash floods and lightning.
