Such a awesome park it was my first time taking my dogs and they had alot of fun

This is the best dog park Ive found in the East Valley. There are so many individual off leash gated areas for your dog to play in. If there needs to be a separation, its easy to step into a different gated off leash area with your pooch. There is an amazing beach area for water play, there are picnic tables so you can eat while dog plays. My favorite is the large area with about 25 tennis balls scattered around. Its easy to play fetch there.

Is dog park is awesome It has a great swimming area for the dogs to run around a plan. They also have nice cleaning stations to get all that sand and dirt off of them before you go home! We drove 40 minutes to get here and it was well worth the drive!

My boyfriend and I used to take our dog here a lot, however I recently found out about the dead body found in the water in 2018, and the condition of the water is very concerning, which with this new knowledge makes me very hesitant to let my dog swim. The grass side is kept nice most of the time, but the last time we took our pup here he contracted kennel cough and brought it home to the rest of our 4 dogs. It’s always a risk you take at dog parks but please, keep your sick puppies at home.

New grass. Park was clean. Beautiful day to swim and fetch his snowman.

Great dog park that really goes beyond the standard. Different areas separated from each other, one with a large slopes pond for swimming. Really top notch park, hard to believe its free

Amazing dog park, and free! Moved from Chicago where youd have to pay a yearly subscription for something this nice. There are 4 fenced off areas: 1 for timid/small dogs, 1 lakefront section where dogs can swim in the lake, 1 large park area, and on medium sized hill section. People pick up after their dogs well here and its honestly gorgeous. I now come back every weekend with my 6 month old dog and its the same energy and fun atmosphere each time

This is one of the nicest dog parks in the East Valley. Water dogs love this place. The park also features a small playground, a walk-around water feature, paved bike paths, and some steep hills for workouts. Parking can get tight when it gets crowded, so be prepared.

It would be nice if they had a water section for small dogs. My dog doesn’t get along with small dogs, so we can’t take him to the water to cool off because everyone brings their tiny dogs into there.My dog was also bit and the owner denied it, despite the fact we literally had to pull their dog off of him...Please watch your dogs.

I loved it dogs were friendly and there was water and a nice to place to run! Been here before loved it just as much!

Great place to exercise your dog, multiple sections to accommodate dogs of different sizes and temperaments, there is a pond with a sandy beach and a place to rinse off or bathe your fur baby. Grassy areas, too. There is also an obstacle course Plenty of parking and shaded places.

I highly recommend this dog park. So glad I did not listen to the naysayers. This is by far the best dog park. The water was clean and the grounds are beautiful. I did pick up several bags of poop, better to take action rather than complain about neglectful dog owners.

Considering this park does not make the city any money, they do an excellent job keeping it clean! Multiple gated grass areas as well as a dog beach! The water for the dogs can get caught up with algae easily, but for the most part it stays clear enough for the pups (and pups ONLY) to enjoy! If your dog likes water, this is the best park in the valley!

Multiple very cool places for dogs to play, plus a basketball court, and a playground for kids.

Big/small dog areas! Picnic tables. Lake/pond as part of the smaller dog park. has a hose off area for when you’re ready to leave.

Hot dog days deserve a pond and a ball. This park has plenty. Cement pond with slopped edges for easy entrance and exit for shy swimmers.A bit of a drive from Scottsdale, but my guy’s worth it.

If you have a dog, you have to visit cosmo park. 2 dog runs and 1 even has a beach! Lots of other dogs to play with too. Highly recommend

My Labraddor had a blast. Park is separated into 3 sections. 1 with the lake, 1 with Grass for big dogs and 1 with grass for small dogs.

Awesome day! Lots of doggie friends and Kool people too! Molly plunged in the nice little pond, but they have showers and someone left some dog shampoo!

Friendly dogs & people all around. Great spot to socialize our puppy. Well taken care of grounds.

We and our dogs enjoy the other canines and humans in the “shy dog” area. There are benches for relaxing. There is water for the dogs. Great place to socialize your pouch with others.

Nice park, but not enough shade. They have one awning and a couple small trees. The water made my dog smell like sea world, even after rinsing him at the supplied hose area.

Dog pond was fun for the dogs. They have a water spout and hose to clean your dog after swimming. The dog park section did not have any shade or seating. But it was still a nice park.

Wish we had more dog parks like this in Arizona. My dog loves running in the man made beach with her ball.

The park was nice, but the water was gross and had lots of stuff growing on the surface. I didnt want my dog swimming in it. Also, half the people werent wearing masks.

Awesome place for dogs. Plenty of different places for the to play

My review might change once the park fully opens up again. But for now it is just fenced in grassy area. Everything is blocked off and closed due to covid It is a pretty cool space if it was open but closed there is not much of a point

The water isn’t fenced in all the way so my dog would only have to swim a few yards to get out so it’s not good for dogs that are good swimmers and don’t have good recall. They also don’t post anywhere when they close down the water so I was a bit disappointed to get there and it was closed. It’s a good park, it just could use more fencing and maybe a social media page that posted any alerts like the water being closed.

This place is awesome. Even after 2 hours we almost literally had to drag our puppy out of here. If you have a very social and high energy dog, this is the park you wanna go to. Theres even a washing station here and 4 individual play areas to meet your pups needs.

Our pup loves this place! Only problem weve had is the gate were the water meets the dirt, if your dog is smart enough, they may find that as the perfect way out!Overall, we love this park, so much fun!

The park has seen better days, it looks that ot needs more maintenance. Other than that the layout of the place is great.

My dog starts to Happy Bark as we nearDogs can play in the waterGated small and large dog play areasGreen grass

Dogs all well behaved..separation areas good ..clean .

Nice dog park. Open, training courses, good seating and water. The dogs can play in the pond and there is a water fountain for dogs to drink and rinse off. Water is a little dirty. Barely any Shade.

Great park! Not just for dogs.. But for the whole family... WE WILL BE BACK!

Great place to socialize and train your pup. Beautiful park!

Fun place for dogs. I just hope that the water doesnt have any floating algae’s because my dogs likes to eat them and get diarrhea after

This place is so cool! Who would have ever thought a dog need a water park

Nice park for big dogs, especially those that like water. I have a small dog though and theres no shade in the small dog area. Also people bring big dogs into the small dog area to wash them with the hose there.

You need to see it for yourself. Lakes, grass, trees and sand for you and your pet to wander in. Very well maintained.

What a fun and wonderful place to take your dogs. The pond was so much fun and the sandy beach was great. It also has a place to wash your dog off before you leave.

OMG My labrador puppy loved this park so much, its huge and all pets that come here are super friendly, I thought my dog how to swim!!

Well done and dog owners are very respectful! Will go back.

Only water park around that Ive heard about my lab loves to retrieve. About a year ago they replaced gravel rocks with sand around water feature. Rock is much less messy the sand gets into everything.....! It might be easier for the maintenance people but sucks for dog owners......gp

GREAT PLACE FOR DOGSLOTS OF ROOM TO RUN AROUNDPOND FOR DOGSCLEAN

My dog Mello loves this park and so do I. The historical significance of Cosmo and her contribution as the first police K-9 cannot be understated as it allows a diverse group of individuals and dogs to come play together under her name.This park features a couple obstacles, one being a set of stairs, and a body of water that dogs are able to play in.

Lots of wide open space and a pond too! There are four separate fenced areas which is nice.

Our pup loves it here. There are always plenty of other dogs there as well. Its one of the few places that she can swim in. The water can be pretty nasty but Im giving it 4 stars because recently it has been clean. There are also plenty of grass areas to play and run around in. The shade is a bit limited though.

Such a wonderful dog park with several areas for dogs at different temperament levels, from timid and quiet dogs to active and playful ones. The dog beach and lake are rare in a dog park and a nice feature. The park is well maintained and there are multiple walking trails too.

Great park friendly people and dogs we love it

Took my dog for the first time, and she had so much fun.

Our back yard patio lol, we love it, our dog more!

My dogs love it here. It is a great place for them to stay cool and burn off energy. My only complaint is that people need to do a better job of picking up after their dogs. The park has many accessible bags and pooper scoopers but there were many poo piles that made the park smell bad.

Love watching the have fun, swim its also a great park to walk ect

Cosmo used to be fun but I feel like park officials abandoned it because it is not well kept. I get that dog parks will smell but Cosmo took it to another level. I can’t even breathe. Also there’s not grass, just dirt. I thought San Tan Village was a nice neighborhood?

Great dog park. Different double gated and fenced areas for large and small dogs. The largest area is on the shore of a small park lake that is great if your dog likes the water. Plenty of area to swim, fetch and run around. Can get crowded on the weekends.There is another separate gated area for general play. It has real grass and is large enough for big dogs to really run. Also contains an agility structure for the dogs to run up and over. Also has a few benches to sit on. No shade inside the enclosure though there are a couple of covered picnic benches outside the gated area where you can watch your dog from. There is a third fenced area for small dogs. Also real grass.Besides the great separate areas there are two dog cool down / rinse stations with water hoses. A really great option during the summer or if your pooch rolls in the dirt after swimming in the lake.Cosmo Dog Park was obviously designed by someone who really knows dogs. It is the best dog park in the Valley of the Sun. Indeed, the best dog park I have ever encountered.

Great park for dogs to run and play and dive! I went there for a project for school and there were lots of dogs there.

My doberman loves it here. Very clean for a dog park keep it up gilbert!!

Fun place to take the dogs. They have an area to wash them off after they have fun.

We visited this park today, as we plan on moving to the area from Chicago in the next year. We found this park to be amazing for the dogs! I think I would still bring my own water for the dogs to drink like we did back at home, in the empty milk jugs and their normal water bowls or a small cooler filled with ice. But this place blows away the parks we have back in Chicagoland! Cant wait to bring my babies here errr- I mean Labs here to swim. And then wash them when done! Then taken then for a leashed walk around the park to dry off on concrete or grass before leaving, perfect!

Wonderful park! Lots of really nice dogs..very busy but dogs all getting along, our dogs had a blast!

Really cool park for humans and dogs alike. They seem to take pretty good care of this place. The weekends are packed with people throwing balls for their dogs into the pond there. Lots of fun and minimal dog issues/fighting.

Very good dog park that will be even better when the lake feature reopens after maintenance.

Its amazing! Its not just a dog park either, it has a park for kids, benches for parents, and it has places where you can have birthday parties! I love it there. My friends and I always hang out there for fun!

Loved this park. There were three separate areas for the dogs, one included the water feature. There were picnic areas outside the park and a kids play area too.

This place is great. There should be more dog parks like this one. Play, swim, or relax...all doggos are happy

My dog loved the access to the lake and playing with the other dogs here. There are areas to hose down your dirty dog after they play. Three areas to choose from - lake access, regular large dog or playful dog area and a more timid dog area.

Great dog park, lake for dogs to play in and 4 different enclosed dog park areas. Plus a nice walking trail adjacent to the 202

This park is fantastic. Many different areas to take your pup. There is a beach area and many stations to get all rinsed off afterward. Plenty of grass and tons of parking. First time we visited this park there was a good collection of dogs. Although, rumor has it that this dog park can be extremely crowded. We will be back for sure!!!

This is a very roomy park with loads of space for activities and relaxation. Its got divided areas for big and small dogs. Friendly faces everywhere! I come here whenever I am in Gilbert with my pup. Its one of my favorite places to visit.

Lots of water and my dog got weared iut

Perfect place for the doggies to cool off and make friends

Good place to take your dog to cool off in the Az heat, also has a wash off station, and a couple other pens with out water

Nice ..well thought out..fun

Always clean and a great way for pets to socialize safely!

I did not go here. The vet said not to take my small dog to these places.

A great dog park. Access to a large dog swimming pond, a timid dog area and two nice dry dog runs. The dog pond does not have a fence surrounding the pond just to the edge, so your dog can swim around the fence. It was busy for the weekend, but it has lots of happy puppies and a couple sour pups, as every dog park will have.

My dog loves this park. The only thing I dont like is that they need to clean the water a little better.

I love this place. It’s great to take the dogs, the family, or just by yourself. It’s fun to just sit and watch the sunset even. Well kept and beautiful!

This is a cool little park but the town should definitely maintain it better. Especially the lake for the dogs. There is an area where you can wash your dog off before you leave, definitely use it.

What a great place to be a dog. Lots of green grass to run in, Even a pond for those that like to swim. My furry friends love coming here. Many nice people to talk to for the humans while the K9s frolic.

So much fun for the pops to run and swim. The water is a great way to cool down. There are actually several enclosed area in the park...one for little and shy dogs...one for obstacle training... and of course the lake and beach area.Be prepared as the dogs do get very dirty and sandy, however there are several wash stations to give them a bath before you leave.

Love this place for my dogs, it’s clean and it’s not too packed so the doggies have room to run and play.

Nice park. Went to take my dog swimming but the dog pond is closed.

My dogs absolutely love this place! It’s pretty & has a lot of options for dogs of all sizes and interests.

My dog loves this park!

I always bring my furry baby here. The layout of the park: large and small dog section. The large dog section is segmented into 3 parts.One segment has an extended concrete pier for dogs to launch their happy-go-lucky selves into the pond. In this section is an sanded beach area for the trotters or fetch & play.2nd section of the large dog park has obstacle courses. 3rd section is another play area.

Absouletly loved that they got to run free and go crazy!!! Had a few issues with people not alot of ppl happy that the dogs were barking at each other . i mean their dogs their gonna play. Def coming back tho this is the first time i see my dogs swim and they just loved it.

Really nice park and something for the whole family.

This is our absolute favorite dog park! It is very well organized and planned out. There are several separate dog areas so you can decide which would fit your dogs personality best. The gated area my huskies enjoy has a beach and a lake so they can swim all they want. There is a place for them to jump off into the water, plenty of shallow water for them to play, as well as deeper water for the brave swimmers. There are tables and shaded areas for the parents to sit and watch the pups play. There is a dog shower area as well to clean them up after they swim and play. The whole park is very pretty and overall is a great park!

This is a really nice dog park. It has a beach for dogs who like the water, a regular dog park area, an agility training area (which was closed for repairs when we were there but should be open in a couple weeks), and another area for timid or smaller dogs. Its very active, at least on Sunday afternoons!

My dog loves this place and we had a very positive experience.

Many different areas to take your dog, small playground, and a basketball court. Has a large pond attached to one of the dog areas. However this park lacks shade in all dog park areas but one. The only part with shade is frequently closed, and the water is nasty looking.

Great area for all size dogs

I love taking my dogs to cosmo dog park and thy love going! i try to bring my friends and their dogs, too. they love swimming in the lake and running around the park in general. its very nice and well-kept.

Great place to let your dog run freely. My dog loves wading in the pond.

Overall, this park is amazing. There are just some owners who think their dog is the perfect little thing. There is a dog does not play with any other dog at the park. We saw it get into a fight today, and the owner literally picked up the opposing dog and told the owner to take their dog and leave. As they were leaving, he made some remarks.Our dog loved the other dog quite frankly; sweetest little thing. Beware of an young man and his Belgian Malinois. Super rude to other owners and their dogs.Also please, PLEASE don’t bring your small dog into the big dog area. You are just asking for trouble at that point. Be respectful of the dog breeds. Just because I have a black German Shepherd, does not mean it’s aggressive.But yeah. Good park, just some owners who need to respect other people’s pets.

Been going to Cosmo before they even officially opened it, I miss having the agility course but its still a great park. They keep it generally clean and lots of fairly nice dogs.

No path lights turned on near the dog park area. Small dog park only has 2 benches to sit on. 2 benches were removed so seating is limited and very dark

Fantastic dog park, it has plenty of shaded and play areas. Atleast 2 areas to hose sand or mud from your pet and legs
