Horseshoe Bay, Whytecliff Park, Shannon Falls.
The first few panos on
West Vancouver show some of Whytecliff Park.
Here is most of what is to see in the Western part of
Howe Sound and
here are some locations further towards Squamish.
If you are in
very good shape, you can go up to the Stawamus Chief (from Shannon Falls), about 700m vertical; excellent view to the entire area, but it takes several hours, so I would rather stay around Horseshoe Bay.
Lighthouse Park in West Vancouver is not really Howe Sound (though there are good views of it from there), but it is a pearl of the entire region; it is ten minutes from Horseshoe Bay (backwards, towards Vancouver).
I don't mean this as showing off, but my panos of this area have almost documentative character.
