Updated November 12, 2026 · By the RoamPlanned team
Short answer: For the famous turquoise lakes, visit from late June through September. July and August are the busiest months. Mid to late September brings golden larches and fewer crowds. December through March is winter sports season, when the lakes are frozen and the scenery is snowy.
Banff by season
| Months | What to expect |
|---|---|
| Late June–August | Lakes ice-free and turquoise, long days, warm afternoons and cool nights. Peak season, so book lodging and shuttles early. |
| September | Cooler days and fewer visitors after Labour Day. Alpine larches turn gold, usually in the second half of the month. |
| October–November | Quiet shoulder season. Snow is possible, some trails and the Moraine Lake road close for the season. |
| December–March | Winter: skiing and snowboarding at the area's resorts, frozen lakes, very cold spells possible. |
| April–early June | Spring thaw. Lakes are often still frozen into June, especially higher ones like Moraine Lake. |
When do the lakes turn turquoise?
The color comes from fine glacial "rock flour" suspended in meltwater, so it is strongest in summer once the ice is gone. Lake Louise usually thaws earlier than Moraine Lake, which is higher. In a typical year, both are ice-free by late June, but it varies with snowpack.
Getting to Moraine Lake and Lake Louise
Moraine Lake Road is closed to personal vehicles. Visitors reach Moraine Lake by Parks Canada shuttle, Roam public transit, commercial tour or bicycle, and the road is typically open from early June to mid-October. Parking at Lake Louise fills early in summer, so shuttles are the easiest option. A Parks Canada pass is required to stop in Banff National Park.
