8. Olympic National Park, Washington St.
A few hours’ drive from Seattle sits Olympic National Park, and the temperate rainforest within it. In fact, it’s one of the largest, if not the largest, temperate rainforests in the world. The wettest place in the continental United States, the scenery is almost overwhelmingly green. You’ll find beautiful coastline, rugged snow-capped mountain peaks and some of the most incredible swimming spots in North America.
