Going-to-the-Sun Road

The Going-to-the-Sun Road is one of the most spectacular mountain drives in the world — a 50-mile ribbon of road that crosses the heart of Glacier National Park, climbing from the forests and turquoise lakes of the valleys to cross the Continental Divide at Logan Pass, 6,646 feet high, amid a world of glaciers, hanging valleys, waterfalls and jagged peaks. A National Historic Landmark and a marvel of engineering, it is the only road to traverse the park.

Completed in 1933 after a decade of perilous construction, the road clings to sheer cliffs along the Garden Wall, passes the Weeping Wall where snowmelt cascades onto the pavement, and offers staggering views at every turn — from Lake McDonald and McDonald Creek on the west to St. Mary Lake and the Wild Goose Island overlook on the east. Open only in the short summer season (after a massive spring plowing of Logan Pass), the Going-to-the-Sun Road is a bucket-list drive and a treasured icon of Glacier and Montana.

Driving the Going-to-the-Sun Road is itself the great experience — a slow, jaw-dropping journey with pullouts and overlooks at Lake McDonald, the Loop, the Weeping Wall, Logan Pass and the Wild Goose Island viewpoint over St. Mary Lake. The road is also the gateway to the park’s finest hikes, with trailheads at Logan Pass (the Highline Trail and Hidden Lake Overlook) and along the route, plus the free park shuttle that lets visitors hop on and off. Cyclists ride the road in spring and early morning. Taking in the overlooks and reaching the high trailheads are the signature draws of this legendary route.

The full road over Logan Pass is open only in summer — typically late June or early July until mid-October, depending on snow (plowing the pass each spring is a huge undertaking) — with July and August the prime, and busiest, months. Early summer brings roaring waterfalls and wildflowers; September offers crisp air and thinning crowds; fall brings golden larch. The lower road sections open earlier and close later. Summer for the full crossing is the highlight; come at dawn or take the shuttle to beat the crowds and parking crunch, and check the road status and any vehicle reservation requirement before you go.

The Going-to-the-Sun Road was conceived to open the heart of Glacier to visitors, and built between 1921 and 1933 in one of the most ambitious road projects of its era — a perilous feat of engineering across cliffs and avalanche slopes, designed to follow the landscape’s contours. Its name comes from Going-to-the-Sun Mountain, rooted in Blackfeet tradition. Dedicated in 1933, the road is now a National Historic Landmark and a National Civil Engineering Landmark. The Going-to-the-Sun Road preserves both a triumph of engineering and the gateway to Glacier’s grandeur, a treasured icon of Montana.

The Going-to-the-Sun Road is a tour through Glacier’s geology, crossing ancient billion-year-old sedimentary rock of the Belt Supergroup uplifted along the Lewis Overthrust, and carved by Ice Age glaciers into the dramatic landscape it traverses. The road climbs glacier-carved U-shaped valleys, skirts cirques and the knife-edged Garden Wall arête, passes hanging valleys whose waterfalls plunge to the road, and crosses Logan Pass on the Continental Divide. Every overlook reveals the work of ancient seas, mountain-building and ice. The uplifted ancient rock and the glacial sculpting created the spectacular landscape the road was built to reveal.

The Going-to-the-Sun Road offers some of the park’s best roadside wildlife viewing, especially around Logan Pass, where mountain goats and bighorn sheep graze the alpine meadows, marmots and ground squirrels scurry the rocks, and grizzly and black bears are sometimes seen on the slopes. Along the route, deer, elk and moose frequent the valleys, and golden eagles and other birds soar the cliffs. The road climbs from forest to alpine, crossing the full range of the park’s wildlife habitats. Watch from pullouts, keep your distance and never feed wildlife — the high country along the road is superb for spotting goats and sheep.

The Going-to-the-Sun Road climbs through the full range of Glacier’s ecosystems — from the cedar-hemlock forest and turquoise lakes of the west, up through montane spruce-fir and larch forest, to the subalpine meadows and fragile alpine tundra at Logan Pass on the Continental Divide, where wildflowers bloom in the brief summer. The road crosses watersheds flowing to different oceans. Built to tread relatively lightly across this landscape, the road reveals the park’s ecological sweep. Protecting the meadows, waters and wildlife along the route sustains both the ecology and the spectacular beauty of this legendary drive.

The Going-to-the-Sun Road holds a treasured place among America’s scenic icons — a National Historic Landmark, an engineering legend, and for many the very symbol of Glacier National Park and the romance of the open road through the high mountains. Named for a peak rooted in Blackfeet tradition and built in the grand era of national-park development, the road embodies both human daring and the overwhelming grandeur of the ‘Crown of the Continent.’ Crossing it is a rite of passage for park visitors. The Going-to-the-Sun Road is a cherished icon of Montana and one of the great drives on Earth.

The Going-to-the-Sun Road runs about 50 miles across Glacier National Park between West Glacier (near Kalispell) on U.S. 2 and St. Mary on the east, climbing over Logan Pass in the middle. A park entrance fee applies, and in peak season timed vehicle reservations are required for the corridor — or ride the free park shuttle. The full road over the pass is open only in summer; vehicle and trailer size limits apply on the alpine section. Visitor centers sit at Apgar, Logan Pass and St. Mary. Check the National Park Service for the road’s open status, vehicle reservations, fees and conditions before driving.

The National Park Service maintains and protects the historic Going-to-the-Sun Road and the landscape it crosses. Visitors help by using the shuttle or arriving early to ease congestion, parking only in designated spots, staying on trails and boardwalks at Logan Pass to protect the fragile alpine meadows, keeping a safe distance from wildlife, carrying bear spray, and packing out everything. The road’s ongoing restoration balances preservation of a historic landmark with protection of the park. Protecting the meadows, waters and wildlife along the route sustains both the ecology and the spectacular beauty of this legendary drive.

The Going-to-the-Sun Road is a narrow, winding mountain road with steep drop-offs and few guardrails — drive slowly, watch for cyclists, pedestrians and wildlife, use pullouts to let traffic pass and to take in views, and never stop in the roadway. Vehicle and trailer size limits apply on the alpine section. Weather changes fast, with snow and ice possible even in summer at the pass. At Logan Pass, stay on trails (this is bear and steep country) and carry bear spray. Keep back from cliff edges and waterfalls. Respect the narrow road, the mountain weather and the drop-offs.

A park entrance fee applies, and timed vehicle reservations are required for the Going-to-the-Sun Road corridor in peak season — check before arrival, or use the free shuttle. Vehicle size limits (length, width, height) apply on the alpine portion between Avalanche and Rising Sun. Park only in designated areas; do not stop in the roadway. Stay on trails and boardwalks at Logan Pass. Pets are not allowed on trails. Drones are prohibited. Keep your distance from wildlife. Pack out all trash. Check the National Park Service for road status, reservations, size limits and current rules before driving.

The road connects West Glacier, Apgar and Lake McDonald on the west with St. Mary on the east, and links to Many Glacier, Two Medicine and the rest of the park, the Flathead Valley and Whitefish to the southwest, and the Blackfeet Reservation to the east. The peaks of the Continental Divide define the region. The Going-to-the-Sun Road is the spine of Glacier National Park, the centerpiece of a Northern Rockies adventure, easily combined with the park’s great lakes, the high trails at Logan Pass, and the gateway towns of West Glacier and Whitefish.

Drive the road early in the morning or in the evening to beat the crowds and find parking at Logan Pass — or take the free park shuttle and skip the parking stress entirely. Reserve a timed vehicle entry in peak season. Allow several hours for the 50 miles with all the overlooks (Wild Goose Island, the Weeping Wall, Logan Pass), and pack layers, water and bear spray for a hike from the pass (the Hidden Lake Overlook or the Highline Trail). Check that the full road is open over Logan Pass, mind the size limits, and savor one of the great drives on Earth.
