North Cascades National Park Travel Guide
When to Go
The spectacular, craggy peaks of the North Cascades—often likened to the Alps—are breathtaking anytime. Summer is peak season, especially along the alpine stretches of Highway 20; weekends and holidays can be crowded. Summer is short and glorious in the high country, extending from snowmelt (late May to July, depending on the elevation and the amount of snow) to early September.
The North Cascades Highway is a popular autumn drive in September and October, when the changing leaves put on a colorful show. The lowland forest areas, such as the complex around Newhalem, can be visited almost any time of year. These are wonderfully quiet in early spring or late autumn on mild, rainy days. Snow closes the North Cascades Highway from November through mid-April.
