North Cascades

Arguably one of the most scenic routes in the United States, Highway 20's ascent from the remote high desert of the Methow Valley brings the craggy peaks of the North Cascades into sharper view. This portion of the North Cascades Highway on Washington Pass traverses the heart of the North Cascade Mountains. Look for the distinctive pinnacled granite ridges owing their formation to eons of fracturing, creating massive cracks in the rock.

Heading east as you descend Washington Pass, the road winds through the heart of North Cascades National Park, skirting the emerald waters of Ross and Diablo Lakes before mimicking the path of the Skagit River on its journey to the pastoral valley below. For over 8,000 years, Native Americans used this corridor as a trading route from the Eastern Plateau country to the Pacific Coast. Beginning in the mid 1800s white settlers arrived in search of gold, fur-bearing animals, and a place to call home.
