Lake McDonald, located within Glacier National Park, West Glacier, Montana 59936, is world-famous for its rainbow-colored pebbles. The eastern shores near Apgar Village and north of Lake McDonald Lodge offer the most spectacular viewing. Dropping to 472 feet at its deepest point, Lake McDonald holds an almost incomprehensible volume of cold, clear water. Lake McDonald Lodge And Its Timeless CharmBuilt between 1913 and 1914, Lake McDonald Lodge is one of those rare buildings that feels perfectly placed in its setting. If Lake McDonald is the heart of Glacier’s west side, Apgar Village is the pulse that keeps everything moving.
