Going-to-the-Sun Road is a scenic mountain road in Glacier National Park in Montana. The Sun Road is the only road that traverses the park, crossing the Continental Divide through Logan Pass at an elevation of 6,646 feet which is the highest point on the road. Construction began in 1921 and was completed in 1932. The road is one of the most difficult roads in North America to snowplow in the spring. Up to 80 feet of snow can lie on top of Logan Pass, and more just east of the pass where the deepest snowfield has long been referred to as the Big Drift. On the east side of the Continental Divide, there are few guardrails due to heavy snows and the resultant late-winter avalanches that have destroyed protective barriers. The road is generally open from early June to mid October, but beware I was at the park on July 3 one year and the road was still closed. If this is the case you will have to take a very long drive around the perimeter of the park to the south to access the western portion of the park.
There are two large lakes on either side of the road Lake McDonald to the west and St. Mary Lake on the eastern side.
From the lake you wind your way up the mountains,
keep your eye open for waterfalls along the way,
the snow drifts can be enormous even in summer,
and of course the mountain scenery is spectacular.
You will eventually make your way up to Logan Pass the highest point on the road.
