5 stars for the variety and well kept trails.
I recall a previous time when this was called "Squaw Peak" but the new name commemorates the "first nation" female soldier lost in the Iraq war.
Most visitors think about he 1.2 mile hike to the top of the summit. While that is a good hike for those with limited time and it is also a great workout, there is much more to be seen in the park. Much more.
Once you've done the peak and are looking for more variety and fewer people, explore the rest of this vast park. I suggest you drive to the very North end of the road where it dead ends. Park there and head North along one of two routes, enjoy a nice loop trek West with a big choice of routes and distances.
I think the nature trail stops with plant identification are great to help folks understand what they're around. Piestewa Trails wander through a landscape of ocotillos, saguaros, barrel cactus and palo verde trees.
Don't forget to bring water.
