Things to Do
Arizona state parks display the Southwest’s dramatic desert landscapes — from Sonoran Desert saguaro forests and red rock formations to mountain forests and archaeological sites. Activities include hiking through canyon country and along desert washes, boating and fishing on desert lakes, camping beneath red rock formations and starry skies, mountain biking on desert trails, horseback riding, exploring ancient cliff dwellings and petroglyphs, birdwatching for unique desert species, and stargazing under some of the darkest skies in the country.
Best Time to Visit
Fall through spring (October–April) is the prime season for lower desert parks, with comfortable temperatures perfect for hiking and camping. Summer (June–August) brings extreme heat (100-115°F) to desert parks — higher elevation parks near Prescott and Flagstaff offer welcome relief. The monsoon season (July–September) delivers dramatic afternoon thunderstorms. Winter is mild in southern Arizona and ideal for snowbird camping.
Visitor Tips
Arizona state parks charge day-use fees of $7-$15 per vehicle. An annual pass is available. Camping reservations through azstateparks.com. In desert parks, carry at least one gallon of water per person per day — dehydration is the number one safety concern. Watch for rattlesnakes and scorpions, especially in warmer months.
