Or Vancouver to Vancouver Island. Depends where you want to start, and when you want to arrive. The Port Angeles ferry ride is pretty boring, the other two routes take you through the San Juan Islands or the Gulf Islands.OK, Vancouver Island, got it.

Vancouver is much more cosmopolitan, it's a world-class city by any standard. Vancouver Island is a quaint backwater in comparison, which is why I like it here.
