What to pack for Banff and Lake Louise in December

Lows around 3°F. Goes under the shell when the wind picks up.

Highs below freezing. A puffy alone won't do it.

Wear one, dry one. Cotton stays wet all week here.

Lows drop to -16 C and wind chill makes exposed skin dangerous within minutes.

Fingers go numb fast at -16 C without insulation between skin and air.

Snow covers the ground and new boots plus wet feet is how day two goes sideways.

Snow reflects sunlight and 7.9 hours of daylight concentrates UV into your eyes.

Check ankles and, if there's a dog, paws and ears every night.

Altitude sickness and slips on ice are both real risks in the mountains.

Daylight ends by 4 pm and your phone drains faster in cold than in summer.

Set it up before you land. Signal drops for long stretches outside cities.

Dark by 5:30pm. Every campsite chore after that is a two-hands job.

Single overhead bin space and checked-bag lines are long in peak season.

Daylight is 7.9 hours so you hike in darkness without a pack to carry a headlamp.

Fits the overhead on every airline that matters. Skip the checked-bag line entirely.

For the passport, the chargers, and the one dry pair of socks.

Rain days number 12 and wet snow soaks regular gloves through in hours.

For the mornings and the nights.

Wind at 12 km/h across your face turns -11 C into something much colder.

Wet socks freeze. Thermal ones keep moisture away from skin even when damp.

Tap water is safe but heating snow for drinking takes fuel and time.

One brick charges the laptop, phone, and camera.

Hotel and cafe wifi is shared with everyone else in the building. A VPN keeps your banking and email to yourself.

International travel and mountain terrain make it easy to lose a bag.

Heavy winter gear fills fast and rolling luggage handles snow better than dragging.

Wet snow soaks through fabric and packing cubes keep damp gear separate.

Checked luggage holds the bulk of winter clothes that won't fit in carry-on.

Humidity at 86 percent plus snow melt means clothes stay damp for days.

Lows around 3°F. One blanket that packs small covers the car, the campsite and the beach at sunset.

Steep mountain terrain and snow cover make footing uncertain without poles.

Snow gets into regular boots at the ankle. Gaiters seal that gap.

Altitude at 2126 m plus snow reflection burns lips fast, even in December.

Mountain roads wind through passes and altitude affects inner ear balance.

Altitude and dry cold air stress your immune system before you touch anything.

Cold batteries die mid-charge. Short cables let you swap devices without unplugging.

Crossing into Canada requires your passport and border lines move slowly in winter.

International flights mean your luggage passes through multiple hands.

Winter coats and boots compress down, giving you room for layers underneath.

Hanging bags keep toiletries accessible when you shower after wet snow hikes.

Hands get cold even in gloves when you stop moving on the trail.

Sitting still outside at -16 C numbs toes despite good boots.
