Flightseeing, anyone?
SFO to Vancouver Island (Campbell River, YBL) one way for about 170$, several dates in June. For an extra ~11$ you can add a third, very short segment to YQQ (Comox).
Routing goes with Air Canada to YVR, from where you take Central Mount Air's Beechcraft 1900. :-) Window seats only = great view over Vancouver, Gulf Islands and Vancouver island, if the weather is fine. (Except maybe seat B in row 9, but that row is to be avoided anyway.)
Me, I would love to fly that in July, but the cheapest I can find is a SJC-LAX-YVR-YBL for 255$.
