The Going-to-the-Sun Road (GTTSR) crosses Glacier National Park from East to West. For a good part of its length, it hugs the mountains on either side of Logan Pass, the highpoint of the road, and a three-way continental divide (north, east, west). It is narrow, and twists and turns for miles, requiring slow driving speeds. There are many pull-outs or stopping places, from which you can see mountains across the valleys.
