Going-to-the-Sun Road

State: Montana. Type: 50-mile scenic mountain road bisecting Glacier National Park, crossing the Continental Divide at Logan Pass (6,646 ft), the road's highest point. Built 1921-1932, formally dedicated July 15, 1933; a National Historic Landmark (designated 1997) and on the National Register of Historic Places (1983). The alpine section over Logan Pass typically opens roughly early July and closes around mid-October, snow and weather permitting; lower sections stay open year-round. Vehicles over 21 ft long or 8 ft wide are restricted on parts of the route.

Going-to-the-Sun Road is a 50-mile engineering landmark that carries visitors across Glacier National Park in northwestern Montana, climbing from the cedar forests around Lake McDonald on the park's west side, over the Continental Divide at 6,646-foot Logan Pass, and down to St. Mary Lake on the east side. Built between 1921 and 1932 and formally dedicated in 1933, the road was designed by National Park Service landscape architects to follow the contours of the Garden Wall escarpment rather than cut straight through the mountains, minimizing its visual impact at the cost of a more difficult, expensive build. It is the only road that crosses the park and is widely regarded as one of the most scenic drives in the United States, passing glacially carved valleys, waterfalls, alpine meadows and frequent wildlife, including mountain goats and bighorn sheep near Logan Pass and grizzly bears near Two Dog Flats. Its historic and engineering significance earned it simultaneous National Register, National Historic Landmark and Historic Civil Engineering Landmark status.

Going-to-the-Sun Road runs through the heart of Glacier National Park in Flathead and Glacier counties, in far northwestern Montana near the Canadian border. It connects the park's west entrance near West Glacier, close to Glacier Park International Airport in Kalispell, to the east side near St. Mary, crossing the Continental Divide at Logan Pass roughly 32 miles from the west entrance and 18 miles from the east.

Glacier National Park has a mountain climate with short, mild summers and long, snowy winters; snowfall at higher elevations like Logan Pass can be substantial, which is why the alpine section of the road closes seasonally. Summer daytime temperatures in the valleys are generally mild (60s-70s Fahrenheit), while Logan Pass and other high points stay noticeably cooler and can see snow even in summer months. Check current road and weather conditions on the park's website before any visit, since conditions can change quickly at elevation.

The road is only open in its entirety, over Logan Pass, roughly from early July through mid-October (the 2026 season opened fully on June 22); exact opening and closing dates depend entirely on snowpack and are announced by the park each year. Before the alpine section opens to vehicles, cyclists and hikers can often access sections of the road during a spring hiker/biker window. Mid-summer (July-August) offers the most reliable full-road access but also the biggest crowds; September offers cooler weather and thinner crowds if the road is still open.

Going-to-the-Sun Road was conceived by Glacier National Park superintendent George Goodwin around 1917, and construction proceeded from 1921 to 1932 under a design ultimately shaped by National Park Service landscape architect Thomas Chalmers Vint, whose alignment along the Garden Wall reduced switchbacks and visual impact at greater engineering cost (the finished road cost about $2.5 million). It was formally dedicated on July 15, 1933. The road's blend of scenic design and civil-engineering achievement led to later recognition on the National Register of Historic Places (1983) and as a National Historic Landmark (1997), making it the first road recognized simultaneously as a National Historic Place, National Historic Landmark, and Historic Civil Engineering Landmark.

Driving the full 50-mile road, roughly a two-hour trip without stops, is the central activity, with numerous overlooks such as Jackson Glacier Overlook offering some of the park's best glacier views. Hiking trailheads along the road, including access to Hidden Lake near Logan Pass, let visitors get out of the car for alpine scenery. Cycling sections of the road is popular, especially during the spring hiker/biker window before the alpine section opens to cars (note the mid-afternoon cycling restriction near Logan Pass in peak summer, roughly May 24-September 8). Wildlife viewing, particularly for mountain goats and bighorn sheep near Logan Pass and occasional grizzly bears near Two Dog Flats, draws many visitors to pull off at overlooks.

Logan Pass, at 6,646 feet, is the road's highest point and the access point for the popular Hidden Lake Overlook trail. Jackson Glacier Overlook offers a long-range view of one of the park's namesake glaciers. Lake McDonald, on the west side, is the park's largest lake and a scenic anchor near the road's western end, while St. Mary Lake anchors the east side. The Weeping Wall, a roadside waterfall that runs over the pavement in early summer, is a well-known feature along the alpine stretch.

Glacier Park International Airport (FCA), in Kalispell, is the nearest airport, roughly 30 miles (about 40 minutes) from the park's west entrance near West Glacier. From West Glacier, the road runs directly into the park; the east entrance near St. Mary is reached via US Highway 89. As of the 2026 season, the park reported no vehicle-reservation requirement for park roads, though this policy has varied by year and should be reconfirmed before a visit.

The lower-elevation sections of the road (near West Glacier and St. Mary) are accessible year-round, weather permitting, but the alpine section over Logan Pass opens only seasonally, generally by early July and closing by the third Monday of October, with exact dates set annually based on snow-clearing progress and no fixed calendar date. Check the park's Going-to-the-Sun Road status page (nps.gov/glac) for current conditions before any visit, especially in late spring or fall.

As of research, Glacier National Park's standard entrance fee was $35 per private vehicle in summer ($25 in winter, Nov. 1-April 30), $30 per motorcycle ($20 winter), and $20 per person on foot or bicycle age 16+ ($15 winter); a park-specific annual pass was $70, and America the Beautiful annual passes ($80 resident/$250 non-resident) are also accepted. Non-US residents age 16+ pay an additional $100 per-person fee unless holding an annual pass. The park does not accept cash. Confirm current fees on nps.gov/glac before visiting.

Driving the full road takes about two hours without stops, but most visitors budget a half to full day to include overlooks, a short hike near Logan Pass, and time for wildlife viewing and photos.

West Glacier, at the road's west end, has motels and cabins just outside the park entrance, while several historic lodges operated by a park concessioner, including Lake McDonald Lodge and the Village Inn at Apgar, sit inside the park along the route. On the east side, the Rising Sun Motor Inn sits directly on Going-to-the-Sun Road a few miles from St. Mary, and the town of St. Mary itself has additional lodging just outside the park boundary. Kalispell and Whitefish, both within about an hour of the west entrance, offer a wider range of hotels for visitors preferring a larger town.

West Glacier Village, at the park's west entrance, has a cluster of casual restaurants and gift shops just outside the gate. In-park lodges such as Lake McDonald Lodge and the concessioner-run properties along the road offer their own dining rooms, while the St. Mary area on the east side has additional casual restaurant options. Kalispell and Whitefish, roughly 30-40 miles from the west entrance, provide a broader selection for visitors staying outside the park.

Lake McDonald, the park's largest lake, sits near the road's west end and offers boating and lakeside trails. Many Glacier, on the park's less-crowded east side, is a short drive from St. Mary and known for dramatic peaks and wildlife. The town of Whitefish, about an hour from West Glacier, adds a resort-town base with its own ski hill, shopping and dining for visitors extending their stay.

Glacier Park International Airport (FCA) in Kalispell, about 30 miles from the west entrance, is the closest airport with commercial service. Amtrak's Empire Builder line stops near West Glacier and East Glacier, offering rail access near the park's entrances. A seasonal shuttle service has operated along Going-to-the-Sun Road during peak summer months in some years; check current shuttle availability on nps.gov/glac.

The road's alpine section has narrow lanes, steep drop-offs and hairpin turns, particularly on the west side approaching Logan Pass, so drivers should heed vehicle size restrictions (21 ft length/8 ft width limits in places) and drive cautiously, especially in fog or rain. Wildlife, including bears, are commonly seen near the road; keep a safe distance and never approach or feed animals. Weather at elevation can shift rapidly even in summer, so carry layers and check conditions before hiking near Logan Pass. For any emergency, dial 911; park dispatch can also be reached through headquarters at 406-888-7800.

Layered clothing is essential, since temperatures at Logan Pass are noticeably cooler than the valley floors and weather can change quickly. Sturdy footwear helps for any stops at trailheads like Hidden Lake Overlook, and sunscreen and sunglasses are worth carrying given the high-elevation sun exposure. Bear spray is recommended for anyone hiking away from the road, and a full tank of gas is wise before starting the drive, since services are limited along the route itself.

Because the alpine section opens on a weather-dependent schedule with no fixed date, check the park's current road-status page before planning a trip timed around driving over Logan Pass. Early-morning starts help avoid the heaviest traffic and parking congestion at popular pullouts like Logan Pass in peak summer. Cyclists should note the seasonal mid-afternoon riding restriction near Logan Pass, and drivers of larger vehicles should double-check the road's length and width restrictions before setting out. Fueling up before entering the park is worthwhile, since services along the road itself are limited.

Dial 911 for any emergency. Glacier National Park's headquarters, near West Glacier, can be reached at 406-888-7800; the Apgar Visitor Center's information line is 406-888-5441.
