Excellent place to bring your dog! The owners here always seem respectful. It's a great place to get some human interaction when you've had a long day working from home too. The place is absolutely huge. Unfortunately, as with every other dog park, the grass is non existent so when I brought my dog here on a rainy day, she was a bit of a mess.
My routine is bringing my dog over to the lake side, let her run around there for a while, play in the water and chase the big dogs, then bring her to the "dirt" side for more running around. They have a special area where you can hose your dog down after she gets dirty. I usually have a towel I keep in the trunk to dry her off before putting her back in the car.
My dog loves playing with little dogs and they have this great (grassy) area for "timid" dogs, but my dog is the least timid in the would and she would probably upset the other dog owners there so we stick with the 2 large parks.
Something else to note, they there is a nice ramada area in case you do find yourself out there on one of the 3 days out of the year it rains. I been going here for a long time and didn't even realize it!!
The bad thing is I do see a lot of dog poop around, I wish dog owners would be more responsible. I hear Gilbert partnered up with ASU to put in this device where you put in dog poop and it exports electricity to power the lights in the park, if that is true, hopefully the owners will be more motivated to clean their dogs ish.
You should for sure bring your dog here at least once, even if you live on the other side of town, it's worth the drive, and you can grab a bite to eat that the famous Joe's Farm Grill, a couple blocks away!
