This is one of the best dog parks in the area. I live in Phoenix and drive to this one. It has three different fenced areas. Usually one two are open at a time so there is one for the big dogs and one for the small dogs. I have two small dogs so it is nice to know that my dogs can play with other dogs their size. Most of the time the people are friendly and social. The reason I gave it only 4 stars is because there are those people that will bring their big dogs in with their smaller dogs because they think their big dog is ok with the little ones. There have been instance where the big dogs have bullied the little ones and have made others mad. I also love that this place is very populated most of the time. I usually like to go around 8pm because that's when other start to bring their dogs. It is huge and equipped with a sand area so my dogs always find something to do.
