What Is the Going-to-the-Sun Road?
The Going-to-the-Sun Road is a renowned 50-mile (80 km) scenic highway traversing Glacier National Park in Montana, USA. It is the only road that traverses the entire width of Glacier National Park, running from West Glacier near Lake McDonald to St. Mary on the eastern boundary of the park. Completed in 1933 after over two decades of construction, the road climbs to Logan Pass (6,646 feet), the highest point accessible by car in the park, crossing the Continental Divide.
It’s more than a transportation route—it’s a national historic civil engineering landmark. Designed to blend into the rugged mountain landscape, the road is both a feat of design and a gateway to Glacier’s most beautiful sights.

History and Engineering Marvel
The idea for a trans-mountain road in Glacier began shortly after the park's establishment in 1910. Construction started in the early 1920s and faced enormous challenges, including harsh weather, steep terrain, and the need to preserve the pristine environment. Stone guardrails, known as "going-to-the-sun" walls, were hand-built by stonemasons to maintain natural aesthetics.
When the road was completed in 1933, it revolutionized access to the park. Previously, visitors had to travel via horseback or by a series of disconnected roads. Today, it remains one of the finest examples of early park infrastructure and was added to the National Register of Historic Places in 1983.

Route Overview: West to East
1. West Glacier and Lake McDonald:
Start your journey in West Glacier, passing through the lush cedar forests of the Apgar area. Lake McDonald, the park’s largest lake, dominates the early miles of the road, offering reflections of the surrounding peaks and colorful pebbles along the shore.
2. Avalanche Creek and Trail of the Cedars:
As the road begins to climb, you’ll pass Avalanche Creek, a popular stop for short hikes. The Trail of the Cedars is an easy, wheelchair-accessible loop through ancient western red cedars and hemlocks, with a spur to Avalanche Lake.
3. The Climb to Logan Pass:
This is the road's most thrilling stretch. As you ascend the Garden Wall, dramatic switchbacks hug the cliffs, revealing jaw-dropping views of glacial valleys and waterfalls like Bird Woman Falls. This section typically opens later in the summer due to heavy snowpack.
4. Logan Pass:
At the crown of the road is Logan Pass, the highest point on the route. Here, you can visit the Logan Pass Visitor Center, enjoy panoramic views, and hike the popular Hidden Lake Overlook or Highline Trail. Wildlife sightings—like mountain goats and bighorn sheep—are common.
5. East Side Descent to St. Mary:
On the descent, the landscape transitions to wide-open alpine meadows and aspen groves. St. Mary Lake provides postcard views, especially of Wild Goose Island, one of the most photographed spots in the park.

Seasonal Access and Vehicle Restrictions
Due to heavy snowfall, the road is only fully open from late June to early October, depending on the snowpack and spring conditions. The Logan Pass section is the last to open and the first to close.
To protect the narrow alpine section, vehicle restrictions apply:
◉ Vehicles longer than 21 feet or wider than 8 feet are prohibited between Avalanche Campground and the Rising Sun area.
◉ Bicycles are allowed but have seasonal restrictions in the alpine section due to safety concerns.
As of recent years, a vehicle reservation system is required during peak summer months. Visitors must secure both a park entrance pass and a timed-entry ticket for the Sun Road corridor.
