Hit up Whidbey Island. Most scenic spot after Mt Rainier is Deception Pass at North End of the island. There’s a nice campground at Deception Pass State Park. If the weather is clear you get awesome views of both the Cascade and Olympic mountain ranges, driving up the island, especially from Greenbank Farms, about halfway up the island. This time of year, though it can vary, daytime temps tend to be in the 40s, and no snow. Any supermarket in the region will have a selection of smoked salmon options.
