We have finally made all of our reservations. So, as promised, here is our itinerary. We start off at Greyland Beach SP, move to Washington City Park in Anacortes, then to Birch Bay SP, Rasher SP, and end up at Camano Island SP. Arriving Greyland SP July 11, departing Camano Island SP August 5th so we average about 5 days per park. Gives us lots of time to explore.
We have planned day trips to Deception Pass, Whidbey Island, and a ferry trip to the San Juan's. Anything else you recommend near these campgrounds or along this route - restaurants, attractions, etc. We hike, bike ride, and will do day trips up to 50 miles or so one way.
Thanks again for all your input. It helped a lot! Safe travels.
