America’s Alps sit in northern Washington and you can drive straight through them for free

They call it America’s Alps

You can drive 140 miles through some of the most rugged mountain scenery in the country, and you won’t pay a dime to enter the national park along the way.

State Route 20, the North Cascades Highway, cuts across northern Washington from the green Skagit Valley to the dry Methow Valley on the other side.

Snow-covered peaks rise sharply above forested valleys on both sides of the road, and more than 300 glaciers hang from the ridgelines.

The whole route is part of the Cascade Loop, a 400-mile circuit through the Washington Cascades, but this 140-mile stretch through the middle is where the mountains really crowd in around you.

Tribes traded on this route for thousands of years

Long before asphalt, Native American tribes used this mountain corridor to move between the Pacific Coast and the eastern plateau.

The route carried trade goods for thousands of years before white settlers showed up after the California Gold Rush of 1849, chasing gold and fur.

A wagon road went through in 1896, but it fell apart within a decade. The state kicked plans for a modern highway down the road for decades after that.

The route you drive today finally came together in the late 1960s and early 1970s.

No entrance fee for 684,000 acres of park

North Cascades National Park doesn’t charge you to get in.

You can pull over at overlooks, stop at trailheads, and walk into visitor centers without reaching for your wallet. That’s rare for a national park.

Most trailheads in the surrounding national forest do need a Northwest Forest Pass or an America the Beautiful Pass for parking, so keep that in mind.

The park itself covers about 684,000 acres, and with the Ross Lake and Lake Chelan National Recreation Areas added in, the whole complex stretches close to 700,000 acres.

Glacial flour turns Diablo Lake turquoise

Diablo Lake is one of the most photographed spots along the entire highway, and when you see the color of the water, you’ll understand why.

Glaciers grind rock into fine particles called glacial flour, and streams carry it into the lake. That silt gives the surface a turquoise color you don’t expect to see outside the tropics.

The effect is strongest on sunny days in July, August and September when glacial melt peaks.

Pull into the Diablo Lake Overlook right off the highway for parking and wide views of the surrounding peaks and the historic Diablo Dam.

Liberty Bell towers at 7,720 feet over Washington Pass

Washington Pass is the highest point on the highway at 5,477 feet, and you can take in the view without breaking a sweat.

A short, paved, wheelchair-accessible trail leads to a lookout where the mountains fill every direction. Liberty Bell Mountain dominates the scene at 7,720 feet, and the jagged Early Winters Spires rise beside it.

Many travelers call this the finest roadside viewpoint in all of Washington. You can see why.

The whole spread of rock and sky sits right there, a few minutes’ walk from your car.

Seattle still runs this little company town

Newhalem sits along the Skagit River, and Seattle City Light still owns and operates it.

The public utility has run hydroelectric dams on the upper Skagit since 1918, using three of them: Gorge, Diablo and Ross.

You can poke around the Skagit Information Center, step into the historic General Store, and find Engine Number 6, a restored Baldwin steam locomotive sitting on Main Street.

Cross one of the footbridges over the Skagit River and you’re on the Trail of the Cedars, a 0.6-mile loop through old-growth forest.

Colored lights have lit these falls since the 1920s

Near Newhalem, a short trail follows Ladder Creek uphill to a waterfall wrapped in gardens. Seattle City Light first strung colored lights on the falls back in the 1920s to show off what electricity could do.

The original bulbs are long gone, replaced by modern LEDs, but the light show still runs on summer evenings.

During the summer season, park rangers give talks on Seattle City Light’s history in the North Cascades and then walk you out to the illuminated falls. The gardens glow against the dark forest behind them.

Gorge Creek drops 242 feet into a granite gorge

About two miles east of Newhalem, the highway crosses a bridge over a deep granite gorge. Below you, Gorge Creek drops 242 feet in a tiered waterfall.

A pedestrian walkway on the bridge puts you right above it. From the parking area, a short paved trail leads to overlooks of Gorge Lake and Gorge Dam below.

The whole stop takes about 30 minutes and has restrooms, making it one of the easiest breaks on the drive. You don’t even need to leave the pavement.

A paved trail leads to an alpine lake at Rainy Pass

Near milepost 158 at Rainy Pass, a two-mile round-trip trail takes you to an alpine lake surrounded by high cliffs. The trail is fully paved and wheelchair accessible, with only about 70 feet of elevation gain.

At the end, benches sit at the water’s edge, and waterfalls cascade down the rock walls above. In the fall, the shoreline lights up with golden and red leaves.

The walk takes 20 to 40 minutes each way, so it’s an easy stop even if you’re mostly there for the drive.

Over 400 miles of trail for every kind of hiker

If you want to get out of the car, you’ve got options.

The Thunder Knob Trail near Colonial Creek Campground runs 3.6 miles round-trip and gives you views of Diablo Lake and Pyramid Peak.

The Maple Pass Loop covers about seven miles along ridgelines, and in fall, golden larch trees line the trail.

For something bigger, the Cascade Pass and Sahale Arm route passes through wildflower meadows with glacier views.

Altogether, more than 400 miles of trail run through the park complex, from easy strolls to demanding backcountry routes.

Winthrop’s wooden boardwalks and smokejumper base

At the eastern end of the highway, the town of Winthrop greets you with an Old West theme, wooden boardwalks, and a main street lined with shops and galleries.

The Shafer Historical Museum walks you through Methow Valley history from the 1880s to the 1940s in a collection of preserved buildings.

The North Cascades Smokejumper Base, where smokejumping started in 1939, runs seasonal tours led by active smokejumpers.

In winter, the Methow Valley has the largest cross-country ski trail system in North America, with more than 120 miles of groomed trails.

Fill your tank before you cross the mountains

The highway closes every winter, typically from late November through mid-April, because Rainy Pass and Washington Pass can get up to 15 feet of snow.

No gas stations or services sit between Marblemount on the west side and Mazama on the east, so fill your tank before you head into the mountains.

The drive is popular enough that on spring opening day, people line up before sunrise to be among the first across. If you’re planning a trip, aim for mid-April through late November.

Drive the North Cascades Highway in Washington

You can reach the western end of the scenic byway near Sedro-Woolley from Seattle in about two to three hours via Interstate 5.

The 140-mile route runs east to Twisp in the Methow Valley, passing through North Cascades National Park at no charge.

Key stops include the Diablo Lake Overlook, Washington Pass Overlook, Newhalem, Gorge Creek Falls and Rainy Lake Trail.

The highway typically opens in mid-April and closes in late November, though exact dates shift with the snowpack each year. Check the official website for current road conditions before you go.
