A shimmering turquoise reservoir threading through the glacier-carved peaks of the North Cascades, Ross Lake National Recreation Area follows the Skagit River corridor and protects the 23-mile-long lake behind Ross Dam. The NRA is a gateway to backcountry boating, peaceful paddling, and lakeside hiking, with old-growth forests rising from the water’s edge and jagged summits like Jack Mountain towering overhead. It offers a serene, mountain-locked escape where the only access to many coves is by boat or trail.
Best season — July through September, when snowmelt stabilizes, water conditions are calm, and backcountry access is at its best; clear-sky nights also allow for stargazing over the lake.

Managed by the National Park Service, this area of Washington state provides access to a remote wilderness experience along the Skagit River corridor. The recreation area’s unique setting preserves a quiet atmosphere where forested shorelines and steep peaks define the landscape.
