Glacier in October: what the park service says

October is the month Glacier's alpine road shuts. The park says Going-to-the-Sun Road usually stays fully open until the third Monday in October, weather allowing, after which the west-side gate moves back to Avalanche Creek or Lake McDonald Lodge and the road beyond it is left to hikers and cyclists. The visitor centers close in late September and early October, but the Apgar wilderness permit office stays open through the end of the month. The last color of the year comes from the western larch, which turns yellow in mid-October; the park notes that Highway 2, along the southern boundary, is sometimes the best road for seeing it.
