The state's signature
Saguaro crown bloom
The state flower opens on top of fifty-foot cacti — and each waxy white bloom lasts less than 24 hours. Late May, whole saguaro forests wear crowns for the bats and doves that pollinate them.
Seasonal RV-timing verdict
When Arizona is at its best
Arizona's prime RV window is October to April. Desert heat becomes unbearable in summer; winter and shoulder months bring pleasant days for hiking and camping in the south. Shoulder-season play: May and September can work in higher elevations like Flagstaff but plan water carefully everywhere.
Know before you go
Monsoon thunderstorms July-September bring flash floods in canyons and washes. Summer highs regularly exceed 110F in the south.
