The off-leash dog park at Westwood Lake is under the power lines on the far side of the lake and the trails to get to it are all on-leash. The closest access point is a parking lot on the corner of Arbot Road and Ridgepoint Drive.
As you are hiking, keep your eyes peeled for the shortcut. It makes the on-leash hike from the parking lot to the power lines significantly shorter.
The hike itself is very nice but this “dog park” is not one of our favourites. We appreciate cities adding dog parks wherever they can, but the off-leash area is a little too far out of the way and not particularly scenic or pretty.
