After arriving at Campbell River on Vancouver island you must take a five minute ferry ride to Quadra and then drive to the ferry terminal that then goes to Cortes, This is a 45 minute ferry ride. The few on the ferries are very beautful thought.
The community on Cortes Island is very friendly and one of the many methods of transporrtation is Hitch Hiking. Unfortunately things on the island tend to be very spread out, so not everything is in walking distance, but all the wide open space is one of Cortes Islands many draws.
Ok, so your probably going to want to get out to one of the Gulf Island - there's several different departure points but the 2 most popular ones are Horseshoe Bay and Tsawwassen. Our ferries can ship cars as well as foot passengers but they do tend to get busy on the weekends (especially holiday ones ~ so book in advance 1-888-724-5223 ) To get to Horseshoe Bay, you want to get downtown and then cross Lions Gate, once across stay in the left lane and follow the hair pin. At the first major intersection make a right, you'll be on Taylor Way. Follow TW up the hill for a while till you see a sign for Whistler / Horseshoe Bay etc. Stay on the upper levels highway till you see signs for HB, take the exit !! (it's well marked so don't worry) To get to Tsawwassen take highway 99 (accessible from Oak Street) and once your past the tunnel start looking out for signs that say Tsawwassen / Ferries ~ 10-15 after tunnel ( not too long ). I'm not quite as familiar with the Tsawwassen terminal, sooooo ---->www.bcferries.com
Vancouver is surrounded by a number of different islands that are linked to gether by a ferry system. Taking your car to the various islands is expensive but possible. You can even reserve a spot in advance. This is a small ferry to one of the smaller islands (Bowen). The tourists love taking the ferries because it affords you an excellent view of the islands and sealife as you travel.
