September trade-offs
- ↓Larch Valley parking is even worse than summer Moraine Lake — go pre-dawn or shuttle only
- ↓First snow possible above 2200m; alpine huts (Egypt Lake, Skoki) need winter gear
October trade-offs
- ↓Lake Louise and Moraine Lake roads close by mid-October for the season
- ↓Snow line drops to 1500m — many alpine routes already winter
