In A Nutshell:
-The White Tank Mountains are a nice escape from the grid of greater Phoenix.
-If you are seeking a quiet refuge surrounded by a plethora of big saguaro cactus' w/ plenty of trails to walk, run or bike, then this is your place.
-There's even a stand-alone library w/ a small gift shop near the entrance.
Overall, I like this park a lot. The tranquility and remoteness alone is worth it if you need a temporary escape from the pressures of life.
