San Juan Islands Bike Tour?

[instatone]

Hey all you knowledgeable bikers,


I am planning a bike-based Labor Day weekend trip all around the various San Juan Islands, using ferries and bike camping. I plan to drive near there from portland and then park my car somewhere,?? then bike around each island and then take ferries...

Does anyone have suggestions for a good route/tour as far as a multi-day bike tour where we could hit a bunch of the islands and have cool bike camping sites, things to do/see, etc? Please include as much detail as possible. I will most likely be doing this as a 3-night adventure /4 day adventure.

Having trouble finding something online...
Thanks
