Jen...I would highly recommend taking the car ferry through the San Juan Islands to Friday Harbor. You can drive to Lime Kiln and Cattle Point lighthouses once you get there. I know Tammy Wolfe has lots of information on this area since she has stayed there quite a few times.

I liked taking the car ferry from Friday Harbor over to Victoria, BC. Victoria is a beautiful city to explore. The ferry arrives quite close to the Butchart Gardens. Fisgard lighthouse is easy to get to on the out-skirts of Victoria. We took a seaplane out of Victoria and flew over the orca pods around the San Juan Islands.

From Victoria, you can take the car ferry to Port Angeles, WA and you're very close to Olympic National park.
