The best months for Banff, Canada: weather, crowds and prices through the year.
Spring and autumn usually bring mild weather and fewer visitors to Banff: the light is softer and rooms are easier to find.
The high season is busiest and most expensive; book early, or travel at the edges of the season for the best of both.
