One star because I'm comparing it to the one in Scottsdale. This place is sketch-ee!!!
Dimly lit, so the only dog I'd bring here is a German Shepherd or Doberman... and that's to protect me! Since I have a tiny Morkie, I pack my 9mm instead.
Like most dog parks there's a big/active dog section and a little/passive section. Thanks for the signage City of Phoenix, too bad no one pays attention. Big dogs in the small dog section ALL THE TIME.
Usually what I end up doing is driving here (5 minutes away) to feel it out, and then 9 out of 10 times I make the 20 minute drive to Scottsdale.
One star awarded because it exists. That's about it. On a nice day it's worth walking around the area. There's a cool duck pond nearby. I'll rate that separately.
