There is no BC ferry from Victoria to Tofino. If you want to get there by boat, it will have to be a private charter if you can find one. If you fly, it will be from Victoria to Vancouver to Tofino. You can always take the Tofino Bus Island Express if you don't want to rent a car. I usually rent a car myself. Drive from Vancouver to Victoria, then drive from Victoria to Tofino, then drive from Tofino to Nanaimo and catch the ferry back to Vancouver. You can spend a whole week on Vancouver Island easily.
