Whatever kind of trail you like, it's here. While everyone else is crowding Piestewa and Echo Canyon and North Mountain, you have plenty of parking and your choice of straight up, level elevation or anything in between hikes. There are a few ramadas for hanging out, which makes the weekends busier with more than just hikers.
The trails are pretty well maintained and mostly free of litter. You'll see lots of cacti, chaparral and some snakes, lizards and lots of dogs on leashes. Arrowhead Point or Sunrise Trail will take you up so you can see from Univ of Phoenix Stadium to downtown Phoenix. One of the few hikes south of the Rim in AZ which afford you a water view- thanks to my neighbors down in Arrowhead Lakes.
I'd like to get a better pair of hiking shoes and take on some of the steeper trails from time to time. As always- bring plenty of water (some of the round trips on the roundabout trails will cover over 3 miles) and dress in layers if it is cool out.
