Ross Lake National Recreation Area

Overview

Bisecting the two sections of North Cascades National Park in northern Washington is Ross Lake National Recreation Area. The incredibly scenic Highway 20 (closed seasonally) cuts through the mountains here, less than two hours from Seattle. The rainshadow effect is readily apparent to anyone who crosses these mountains from the lush west to the arid eastern portion of the state. Access to the only boat ramp on Ross Lake actually requires a drive through Canada, but you can also pick up a water taxi near Diablo Dam.

Must-Do Activity

If coming from Seattle, start your visit at the North Cascades National Park Visitor Center on the scenic North Cascades Highway (20). Ross Lake National Recreation Area contains three hydroelectric reservoirs, which have an interesting turquoise color due to glacial silt, especially evident at Diablo Lake Overlook. Nearby, Colonial Creek Campground offers a peaceful forest in which to spend the night and a good jumping off place for a day hike on Thunder Creek or Fourth of July Trails through old-growth forests with colossal mushroom conchs and giant banana slugs.

Best Trail

Summiting Desolation Peak is often found on the bucket lists of the writer Jack Kerouac’s biggest fans, as he did some of his best writing while stationed as a fire lookout here in 1956. The observation tower is not far from the Canadian border and the trek is a daunting task, typically utilizing a water taxi to cross Ross Lake.

Instagram-worthy Photo

Do not drive past Diablo Lake Overlook, an awe inspiring and usually gusty stop along Highway 20. The craggy heights of the geologically young mountains surrounding this spectacular reservoir are magnificent to behold, yet forbidding to enter.
