One of my favorite outdoor activities is hiking. We have beautiful weather for 9 months out of the year, why not take advantage and get outside? And if it is too hot in the valley one can always head north to Prescott, Sedona, Flagstaff, or the Grand Canyon. Arizona offers hiking trails for all levels. Locally, my go to hiking parks are Usery Mountain Regional Park in Mesa and Lost Dutchman State Park at the foot of the Superstition Mountains. And just 2 hours north of the Phoenix Metro Area is Sedona. I haven't been on a trail in Sedona that I did not like. It truly is a magical place. For information on Sedona hiking trails click here.
Because we hike quite a bit in the cooler months, I like to purchase annual passes. Arizona State Parks and Maricopa County Parks offer great trails and keep us busy. We also like to get the Tonto National pass as well. Information on purchasing passes can be found on their websites below. A few things I will say about hiking in AZ is to always hike with plenty of water, don't hike when it's hot, have proper hiking gear, and always let someone know where you will be hiking.
