Eastbound — North Cascades Highway (WA-20) to Winthrop first, then south to Chelan and west over Stevens Pass to Seattle
Over the American Alps
Turquoise glacial lakes, a hairpin over the North Cascades, an Old-West town, and one of America's great fine-dining rooms to finish — all in two days.
The Cascade Loop crosses the wildest mountains in the Lower 48 and comes out the other side in a different world. This run takes the North Cascades Highway — SR-20 — east over the range, drops into the sunny Methow Valley, runs down a fifty-mile glacial lake, and loops back to Seattle. One thing first: SR-20 closes every winter for snow and avalanche, and there's no through-route when it's shut — in 2026 it didn't fully reopen until June 14, the latest since 1974. So this is a summer-and-fall loop; check WSDOT before you go.
Day 1. Breakfast at the Calico Cupboard in the Skagit Valley tulip country, then climb into the North Cascades — the "American Alps," three hundred glaciers, walls of old growth. Walk the easy Trail of the Cedars at Newhalem, then stop at Diablo Lake, an unreal turquoise from the glacial rock-flour suspended in it. Up to the Washington Pass overlook at fifty-five hundred feet, with the Liberty Bell spires above and the highway hairpinning below. Drop into Winthrop, an Old-West boardwalk town in the high desert (the cowboy theme is deliberate, dating to 1972), for dinner at the Old Schoolhouse Brewery and a night at the Mt. Gardner Inn.
Day 2. Down to Lake Chelan, a fjord-like glacial lake fifty miles long and nearly fifteen hundred feet deep — the third-deepest in the country — for a lakeside lunch. Then the run back toward Seattle (the Bavarian-themed village of Leavenworth makes a fine detour on the way) and the finale the whole loop earns: dinner at Canlis, the mid-century Seattle landmark over Lake Union that's been one of America's great restaurants since 1950, and a night at the Inn at the Market, the only hotel inside Pike Place.
And hold the plan loosely — the Cascades give you a hundred reasons to stop. The plan's a backbone, not a cage: the trailhead to a glacier view, the fruit stand in the Methow, the larches going gold over Washington Pass in October, the winery above Chelan. This loop rewards the driver who lets a turnout or a trailhead rewrite the afternoon. Just confirm SR-20 is open before you commit, fuel up before the long no-services stretch over the pass, and pull over when the lake goes impossibly blue. The best stop is the one that wasn't on the list. Go find it.
