So much to do in Seattle - great food, coffee, parks (Kerry Park for a viewpoint, Gas Works Park, and Discovery Park for a seaside nature trail), and obviously the Space Needle.
Beautiful coastal views without having to hike (although lots of trails nearby if you want to!). Drive through Deception Pass (lots of stunning lookouts to stop at), get lunch in Anacortes (we love the fish & chips at Rockfish Grill and Cinnamon rolls at Calico), and stop at Washington Park for a scenic loop.
