Well, almost impossible. You can take the Saturday early morning direct ferry to Tsawwassen. Drive the Coquihalla race track to West Kelowna and arrive by noon. Visit a few wineries and get back to Salt Spring via the evening direct ferry.
Our getaway included an overnight in West Kelowna. And we did visit Quail’s Gate (best modern architecture), Little Straw Vineyards (more our speed with great lunch and wines), and Mission Hill (best views, grounds and artwork).
Both photos are from Mission Hill.
Mission Hill looks lovely!
I have of course a great many images of the place, but I think all the green stand out in the brown of the Okanagan Valley.
