The Mega Flood Route - The Washington Coast to Missoula Mt

If I had choice for a long term campsite, I'd choose the Keller Ferry Campground. It's a waterfront campground with shade trees in an otherwise hot and dry landscape. The drive back up to US2 is a bit windy and steep. But the ferry ride gives access to the lesser known Colville Reservation area, with access north to Canada, west to the Grand Coulee and Okanogan, and east to Gifford Ferry and NW Washington.
