One of my fave mountain preserves to trek on the weekends. You'll never be bored because you'll always be in good company with the fellow hikers. Plenty of trails from easy to moderate and the extreme for the adventurous hikers and runners. I'm all about running up the hills that zig zag back and forth to get your BPM up there. Parking isn't a zoo and accessible from all streets so it's up to you to decide how ambitious you want a workout. Definitely a great spot for mountain bikers whether you are coming up the back trails of Ahwatukee to the front side of Phoenix. Get outside. It's the best kind of playstation!
