Really nice park hidden in plain sight! If you're driving on Northsight by the Vanguard offices, you'll see the sign for this park. I had no idea what to expect but it's really nice!
The park only has about 10 parking spaces so be sure to carpool if you're with a bigger group. Immediately upon parking, you'll see two large sand volleyball courts, one tennis court, a covered Ramada and facilities. Through the Ramada, you'll see a basketball court and playground.
There are two nice fields, one directly west of the parking lot that would be perfect for a small game of pickup soccer or Frisbee. The south field is much larger and can accommodate much larger games and sport. On both fields, the grass is nice and relatively green which is amazing for Arizona. Neither field has many tables surrounding it, so if you're trying to picnic, I recommend snagging the Ramada.
