Less than 200 kilometers northeast of Seattle, North Cascades National Park beckons to hikers with more than 600 kilometers of trails. You can opt for a scenic stroll through the mountain-framed valleys or put your legs to work on paths that lead to views of the park’s more than 300 glaciers. You’ll want to come prepared with several layers of clothing — not to mention, sturdy hiking shoes — as temperatures can change as you climb in altitude. Because there is so much ground to cover (nearly 277,000 hectares), we recommend spending a couple of days here. The park features five campgrounds that can accommodate cars and RVs, three additional campgrounds accessible by boat and 140 backcountry campsites.
