The Deem Hills Recreation area is an awesome recreation area with plenty of trails for people in North Phoenix.
Located in north Phoenix, the Deem Hills recreation area features a dog park, playground, soccer field, and trailhead leading into the neighboring hills.
To begin your hike, get around the dog park by starting at the Circumference trailhead on the north side of the parking lot. To complete the circumference loop counter-clockwise, take a right at the first fork in the trail. The path climbs slowly as it wraps around the south side of the first hill. On the opposite side you'll find another junction where you'll take a right turn and continue east. (Here you have the option to go for a shorter but steeper hike to the top of the ridge if you want.) The path takes you around the other hills and loops back around the north side. This hike takes you around the outer perimeter of the before returning to the parking lot on the west side.
From the 101, take 59th Ave north and continue through Thunderbird Conservation Park. Shortly after you go under the footbridge you'll arrive at a traffic light, where you'll turn left. At this point you'll be on 55th Ave which you can follow all the way to the Deem Hills parking lot which will be on the right.
