About the Park
At the corner of East Warlow Drive and Hannum Road in Gillette, The O-SO Fun Dog Park pairs a splash pad and a pond with plenty of open ground. A double gate opens into the fully fenced space, which is split into small- and large-dog areas so play stays sensible. A shelter and seating give owners shade and a place to rest, a walking trail circles the grounds, and there is a parking lot right there. Entry is free, with hours from 6:00 AM to 10:00 PM daily. Gillette sits in northeast Wyoming's high plains, where summer heat and open wind are the norm, so the water features and shelter earn their keep. Clean up after your dog, as bag stations are not noted here.
infoWhat to Know Before You Go
The O-SO Fun Dog Park is fully fenced, so your dog can run and play off-leash without worry. This makes it a great choice for dogs still working on recall or for owners who want extra peace of mind.
There's a separate area for small dogs, which is perfect if you have a smaller breed that might be intimidated by larger dogs. This is a feature many dog owners specifically look for.
Dogs can enjoy water features here — great for cooling off on hot days. Bring a towel for the car ride home, because your pup will probably get soaked.
Walking trails are available, so you and your dog can enjoy a walk beyond just the off-leash area. Trails are a great option for dogs who enjoy sniffing and exploring at their own pace.
Best of all, The O-SO Fun Dog Park is completely free to visit — no membership or daily fees required.
backpackWhat to Bring
Fresh water and a bowl
Even parks with water fountains can have them out of service. Bring your own to be safe.
Poop bags
Most parks provide them, but don't rely on it. Always come prepared to clean up after your dog.
A towel
Your dog will likely get wet at the water features. Save your car seats with a quick dry-off.
A reflective collar or light-up leash
If you visit near dusk, visibility gear helps you keep track of your dog and stay safe.
High-value treats
Useful for practicing recall in a distracting environment and rewarding good social behavior.
Your dog's favorite toy
A familiar toy can help shy dogs feel more comfortable and give them something to focus on.
