The City of West Vancouver website says dogs are allowed off-leash on the trails at Klahanie Park. Unfortunately, the only trails we found when we visited the park ran along the river, were very short narrow and primitive.
Avy wanted to run down to the fast moving river to go for a swim, but it is lined with slippery boulders and we were worried she would break a leg so she was quickly leashed up for the rest of the walk.
We don’t recommend using Klahanie Park to exercise your dog, there are much better off-leash dog parks nearby.
