Spring
May – early JuneCool, foggy, and raw. Black flies emerge in late May and peak through most of June — this is the one genuinely difficult thing about visiting the region in spring. Lupines bloom along roadsides in June. The landscape is extraordinary but the bugs are real. Fewer visitors than any other season.
Tourism: Very quiet. Most lodging and restaurants operate reduced hours or are just reopening.
Best for serious birders and travelers who don't mind bugs and unpredictable weather.
