This is much larger than i had anticipated and could be a full day trip with a picnic. The walk or preferably a cycle around the water's edge is a good starting point but there is so much more to it. Go up to the viewing point to see Vancouver beneath you - cruise liners and sea planes etc. A great way to start a Canadian adventure.
