Welcome - The Dog Park at Echo Lake Park in Mountainside is just under three acres, with fenced areas set aside for large and smaller dogs. It is accessible for people with disabilities with designated parking areas and sloped paths.

Work is continuing at the park to improve parking, along with water fountains and other improvements.


Location - Entry to Echo Lake is possible either from Mountain or Springfield Avenues in Mountainside.

The Dog Park is in the center of the park. For a map of the park, go to: ucnj.org/ELparkmap

Walking your Dog in our Parks – Dogs and their owners are always welcome in Union County’s parks. What better place for a walk with our “best friends?” But there are rules:

With the exception of the Echo Lake dog • park in Mountainside, dogs must be kept on a leash, no longer than 6-feet. This is for their protection, along with other visitors to the park, human and canine.

Should a dog defecate anywhere in the parks, whether on a macadam walking path, or along a hiking trail in the woods, owners are required to remove any dog waste in a sanitary manner.

Other than at the Echo Lake dog park, dogs are not allowed to roam off-leash. Because of the inherent unpredictability of how they will interact with other dogs and humans, as well as the chance of running into a wild animal, that could have rabies.

All dogs must have a collar with the appropriate rabies tag and license tag of the municipality where its owner resides.

Keeping Dogs and People Safe – Dog owners owe it to themselves and their pets to read the American Veterinary Medical Association’s “Dogs’ Social Lives and Disease Risks.” We have it on our website at: ucnj.org/risks-to-dogs

While not intended to scare dog owners, it outlines how the unknown health histories of other dogs can pose problems for your dog, and even you!

Just as people should stay home from work when they are sick, to prevent the spread of infection, it is just as important for dog owners not to bring a sick dog to a public Park.

Union County Parks regulations require all dogs to be on leash. Violations of these rules carry penalties that include fines to the owner.

So for a happy experience in Union County Parks, please respect fellow visitors, whether two-legged or four.
