Coming from the west, follow the Going to the Sun road up over Logan's Pass and down past Sunrift Gorge. The Sun Point Trail winds to a large rocky outcropping in the middle of St. Mary's Lake.
Make sure to take time and set down the camera in order to just take in the beauty of this place. It's truly breathtaking.
This image was taken at Sun Point in Glacier National Park. St. Mary's Lake beautifully reflects the mountains and cliffs rising up out of her. I have yet to see a 360 degree panorama that equals the majesty of Sun Point.
