Spanning 144.1 miles across northeastern Washington and northern Idaho, the International Selkirk Loop earned its prestigious All-American Road designation for good reason. This extraordinary drive traces a path through the rugged Selkirk Mountains, where pristine wilderness meets small-town charm at every turn.

Beginning at the British Columbia–Washington border on SR 31 and winding to the Idaho–British Columbia border on SH 1, the route reveals a landscape shaped by ancient glaciers and endless evergreen forests. Travelers encounter crystal-clear lakes perfect for kayaking, thundering waterfalls hidden along forest trails, and sweeping mountain vistas that demand frequent photo stops.

Along the way, discover the artistic community of Sandpoint, Idaho, nestled on the shores of Lake Pend Oreille—one of the largest and deepest lakes in the American West. Explore historic mining towns, spot moose and elk grazing in meadows, and find unexpected treasures at roadside antique shops and local wineries.

The best time to drive is late spring through early fall when mountain passes are clear and wildflowers blanket alpine meadows. Allow at least a full day to complete the loop, though the route rewards those who linger with camping, hiking, and genuine mountain hospitality.
