I'm in the beginning stages of planning a trip next summer (late July or early August) for my husband and me while our kids are at camp. ONP (in particular, the Hoh rainforest) has been a dream for me to visit for a couple of decades. I love to hike, bike, kayak, and sit and watch/listen to the water, especially rivers. My husband enjoys this for 5 days or so, and then is antsy. In the past, I've been able to make our trips longer by combining with things he loves (food, wine, art). For instance, we spent 10 days in NW Oregon by including a few days in the wineries and a few days in Cannon Beach for art/shopping. Same thing with a trip to Maine. From all the reading I've been doing, the Olympic Peninsula seems relatively lacking in food/art/charming towns.
The San Juans look like a great place for us to combine our interests, but I'm really not willing to give up on ONP, and I want to do it well. Rather than staying a week in ONP, I'm considering 5-6 days there, followed (or preceded) by 3-5 days in the San Juan Islands. Is this doable? I realize I could spend a week or more in the islands themselves. Is 3-4 days reasonable, or should we make that a separate trip for (??) in the future? The absolute last thing I want is to have 'seen' it all, but enjoyed none. I can always throw a day or two in Seattle on to a trip to just ONP (we've spent plenty of time there, though none in the past 15 years) for some food, art, etc...
If ONP/SJI combo is advisable, is there an efficient way between the 2 areas? I did a mapquest route search from Port Angeles to Friday Harbor to get an idea, and it included 3 ferries, which I'm assuming would be lots of waiting.
