Going-to-the-Sun Road is a 52-mile (84-kilometer) road that bisects Glacier National Park in Montana. The drive is about two hours long if you drive without stopping. It actually crosses the Continental Divide at Logan Pass, which is 6,646 feet (2,025 meters) high.

The road passes through just about every landscape in the park -- glacial lakes and valleys, alpine tundra and cedar forests. You can see actual glaciers from the road, at Jackson Glacier Overlook. Because the road was specially built to traverse the park, it's well-populated with places to pull over and admire the view. Dedicated in 1933, officials named the road after a local mountain. It's also a National Historic Civil Engineering Landmark.

Going-to-the-Sun Road is open from June through early fall. In the winter, the area receives too much snow for the road to be passable. Park personnel spend early spring focusing on snow removal. Summer is the best time to visit Glacier National Park and drive the entire road.
