Phoenix Mountain Preserve is a 7,071-acre big park featuring mountain peaks and deserts but also cacti & native wildlife. It is great for families with kids, solo outdoor enthusiasts, mountain bikers, dogs, and some areas are accessible in a wheelchair.
There are not only wild trails and one of the hardest trails in Arizona - Piestewa Peak, but also great facilities for picnics, bathrooms, a gift shop with some snacks, and benches to sit down and enjoy the peace and quiet.
