Four middle-aged adults are planning a June trip to the west coast. We will arrive in Seattle, rent a car, and visit Washington state, the Oregon coast, and the northern California coast, then depart from San Francisco. We have established our routes in Oregon (mostly coastline) and in California (Redwoods, Napa Valley, and San Francisco). In Washington, we are interested in Seattle, Mt. Rainier, Mt. St. Helens, and Olympic National Park, but we are having trouble deciding on a sensible route to include these stops. So my questions are: 1) What IS the most sensible route to drive to these places? 2) Is the coastline in Washington a must-see, or should we cut inland in order to make the most of our time? We have 12 days to drive this route, but would like to spend a day in Seattle and 1-2 days in San Francisco.
Thanks for any advice!
