Where is the closest dog park to Mount Ommaney?

Boat Ramp Park, by the river off Mount Ommaney drive has a small dog park. A little further away but worth the drive is Windermere Park, with a large area for bigger dogs and an ample separate one for small dogs. To get there, follow along as though going to River Rocks Park, but instead of turning right into it, go a short distance and turn left (into an industrial area). There's lots of parking there and you can follow the walkway along until you get to the dog park.
