This is a wonderful park, and we've often hiked along the other trails, but this one was completely new to us, and what a treat. Sadly dogs are not allowed on some parts of the trail, because much of it lies close to farm land, and there have been issues with dogs harassing the farm animals. 
Well worth a visit though, even without Fido.
The Provincial Parks caches have to comply with the Parks guidelines, as to position, labelling and owner ID, and this cache is in compliance.
