Gabriola is an island, so you will have to get here via ferry (check the BC Ferries web site for schedule information), float plane, or your own boat (or the boat of a kind friend!).
One of the Chamber's members (the Haven) has an excellent web page referring to the many ways to get to Gabriola. Click here to read the Haven's instructions on how to get to Gabriola. While you're at that site, take a look at all the programs and facilities offered by the Haven.
Tofino Airlines flies you from the South Terminal at the Vancouver International Airport directly to Silva Bay in minutes.
