Nobody drives this 50 mile Montana road without stopping and you won’t either

It’s the only road through the park

Going-to-the-Sun Road runs 50 miles through Glacier National Park, from West Glacier on one side to St. Mary on the other. It’s the only road that cuts all the way through.

You could drive it in two hours without stopping, but nobody does that. The overlooks, trailheads, and lakeshores pull you over again and again.

Most people spend half a day or more on it, and the highest point sits at 6,646 feet on the Continental Divide.

Workers spent 11 years blasting through the mountains

Construction started in 1921 when crews began carving what they called the Transmountain Highway through some of the roughest terrain in the Rockies.

They worked for more than a decade and spent about $2.5 million before finishing in 1932. The formal dedication drew over 4,000 people to Logan Pass on July 15, 1933.

Landscape architect Thomas Vint redesigned the upper route along the Garden Wall escarpment to cut switchbacks and let the road follow the shape of the mountains.

The road became the first in the country registered as a National Historic Place, a National Historic Landmark, and a Historic Civil Engineering Landmark.

Rainbow rocks line the bottom of Lake McDonald

Lake McDonald stretches about 10 miles long and drops 472 feet deep, making it the largest lake in the park.

Look down through the water and you’ll see pebbles in deep red, maroon, green, and blue scattered across the lakebed. The colors come from iron in the ancient rock.

Red stones formed in shallow, oxygen-rich water. Green ones formed deeper, where oxygen ran low.

Cold temperatures keep plankton down, so the water stays clear enough to see the bottom. On the eastern shore, Lake McDonald Lodge dates back to 1913 and 1914, built in a rustic Swiss chalet style.

Walk through old-growth cedars to a turquoise lake

The Trail of the Cedars loops about one mile on boardwalks through old-growth cedar and hemlock near Avalanche Creek.

You cross a bridge over Avalanche Gorge, where water has carved a narrow slot through red mudstone over thousands of years. If you want more, keep going.

The Avalanche Lake Trail picks up from there and runs about two more miles to a turquoise glacial lake sitting at the base of towering cliffs. Small waterfalls drop into it from hanging valleys above.

It’s one of the most popular and most accessible hikes along the road.

Eighty feet of snow buries Logan Pass every winter

West of Logan Pass, the road narrows and climbs directly into the mountainside. The Loop is the one big switchback, a sharp hairpin turn where you can look south at Heavens Peak.

Farther along, the West Tunnel punches straight through solid rock. Workers blasted it in the 1920s using 6,000 pounds of dynamite.

Above, the Garden Wall rises as a steep ridge carved by ancient glaciers along the Continental Divide.

Up to 80 feet of snow piles up near Logan Pass each winter, and crews spend about 10 weeks every spring plowing the road open.

Water pours off the Weeping Wall onto your car

The Weeping Wall is a stretch of cliff where water seeps through rock and falls directly onto the road. Construction crews created part of it when they blasted rock and exposed natural spring-fed veins.

In June and July, during peak snowmelt, the water comes down hard. By late summer, it tapers to a trickle.

Nearby, Bird Woman Falls drops nearly 500 feet from a hanging valley between Mount Oberlin, Clements Mountain, and Cannon Mountain.

Several pullouts on the west side of the road give you a clear line of sight to the falls.

Wildflowers carpet the tundra at Logan Pass

Logan Pass sits at the top of the Continental Divide, 6,646 feet up, where the landscape opens into alpine tundra.

In summer, wildflower meadows spread across the pass with species tough enough to survive the harsh alpine conditions.

Two of the park’s most popular hikes start here: the Hidden Lake Overlook trail and the Highline Trail. You’ll find a visitor center with exhibits, ranger programs, and restrooms.

Logan Pass is 32 miles from the west entrance and 18 miles from the east, so you can reach it from either side.

Mountain goats graze the trail to Hidden Lake

The Hidden Lake Overlook trail starts just behind the Logan Pass Visitor Center and covers about three miles round trip.

You begin on boardwalks through fragile alpine meadows, then the path shifts to gravel as it climbs. At the overlook, you look straight down on Hidden Lake with the sharp profile of Bearhat Mountain behind it.

Mountain goats and bighorn sheep show up along this trail regularly.

If you want to keep going, a side trail drops down to the lakeshore and adds about 2.4 miles to the hike.

A cable in the cliff keeps you on the Highline Trail

The Highline Trail starts directly across the road from the Logan Pass Visitor Center. The first stretch hugs the cliff face above Going-to-the-Sun Road, with a cable bolted into the rock for support.

From there, the trail follows the Continental Divide north along the Garden Wall, with views dropping into deep valleys on both sides.

Most hikers do it as a one-way, 12-mile walk from Logan Pass to The Loop and catch a shuttle back.

You’ll pass through prime mountain goat, bighorn sheep, and marmot territory, and an optional side trail leads to the Grinnell Glacier Overlook.

Wild Goose Island rises 14 feet out of St. Mary Lake

Coming down from Logan Pass toward St. Mary, you pass through the East Side Tunnel, a 408-foot passage built entirely by hand in 1931 and 1932.

Jackson Glacier Overlook is the only spot on the road where you can see an active glacier. Then St. Mary Lake opens up, more wind-swept and exposed than Lake McDonald.

Out in the water, Wild Goose Island rises just 14 feet above the surface, surrounded by peaks over 8,000 feet. The overlook above it is one of the most photographed spots in the park.

Grizzlies, goats, and 270 species of birds live here

Going-to-the-Sun Road passes through habitat that supports mountain goats, bighorn sheep, grizzly bears, black bears, moose, elk, and deer.

Near Logan Pass and along the Garden Wall, you’ll see mountain goats and bighorn sheep most consistently. Grizzlies sometimes appear along the east side of the road in open valley areas.

The park holds more than 70 species of mammals and over 270 species of birds. Dawn and dusk give you the best chances, so time your drive if you can.

The 1930s Red Buses still roll with canvas tops down

A fleet of 33 vintage Red Buses still runs guided tours on the road.

The White Motor Company built them between 1936 and 1939, making them the oldest touring passenger fleet still in service in the country.

Drivers go by “Jammers,” a name from the days when they had to jam the manual gearbox into low gear on steep grades. The buses have roll-back canvas tops painted to match ripe mountain ash berries found in the park.

Ford Motor Company donated over $6 million to rebuild the fleet after safety concerns pulled them off the road in 1999.

Before the road opens to cars each year, cyclists and hikers get access during the spring hiker-biker season.

Explore Glacier National Park in Montana

You can reach Glacier National Park in northwest Montana from either side of Going-to-the-Sun Road. The park covers over one million acres and holds more than 700 lakes, over 200 waterfalls, and 25 named glaciers.

Most facilities and the full road open from early summer through mid-October, though the park itself stays open year-round.

Check the official National Park Service website for current road conditions and entry fees before you go. Areas like Many Glacier and Two Medicine give you even more trails and scenery beyond the main road.
