I did this exact trip in late Feb / early March 2022 with my GF (now wife), a friend, and my sister and brother-in-law. We flew into Calgary on a Saturday and rented a car, then were based at the Moose Hotel in Banff until departure the following Saturday. I like to lock-in lodging early but with the get-out-of-jail-free option of free cancellation, which was easy to come by. However the Banff areas had a strong start to the season that year, so I was confident in our itinerary by December. We did luck out some as a major cold spell struck in late Feb but was on its way out by the time we arrived. Three of us had IKON base basses good for 5 days total across Sunshine, Lake Louise, and Norquay.
Here was our itinerary:
Saturday: Fly into Calgary, drive to hotel in Banff, arrival by late afternoon.
Sunday: Skied Sunshine. Surface conditions were excellent with 1-2 inches of fresh over packed powder, though we had off-and-on snow showers with limited visibility in the upper elevations.
Monday: Ski Lake Louise. Again excellent surface conditions with scattered snow showers. Visibility was good enough to avoid vertigo in the alpine, but unfortunately no
Tuesday: off day, rented microspikes in town and hiked Johnston canyon to the lower falls, watched ice climbers for a bit. This was a great short hike, and sees enough traffic that you generally only need microspikes rather than snowshoes. Then continued up to Lake Louise (the lake) to enjoy the Chateau and slide around on the ice.
Wednesday: Sister and brother-in-law departed for Calgary via shuttle. Friend and I skied Sunshine again in 3-4" fresh snow and only high clouds for better visibility. GF enjoyed a spa day at the hotel.
Thursday: Skied Lake Louise again, with more snow showers but very brief cross-valley views.
Friday: Half-day at Mt. Norquay. Conditions were inferior to the other two areas (as expected, more like dust-on-crust) but we enjoyed some variety and the change of scenery. In the afternoon we hiked up Tunnel Mountain just outside town for some great views of the valley and surrounding peaks.
Saturday: morning departure to Calgary and fly home.
Hotel: There are plenty of options in Banff, but I was very happy with the Moose. It's a little unconventional in that the corridors are open-air balconies (like you'd find in a motel) but that somehow makes the rooms feel more like individual cabins. The main selling points for our group were the rooftop hot tub and sauna (which we used daily), and the spa. I was also able to book in advance with free cancellation up until the week before.
Dining: Again, plenty of options here, but one that really stood out was
Bear Street Tavern: great pizza served with sides of honey and chili oil to drizzle on top. On Sundays they had a pizza + stein deal that was an absolute bargain.
If I were traveling solo or with my college buddies the Calgary-Castle-Fernie-Banff loop sounds great. But for a group that wanted a base that combined good skiing with plenty of other options, Banff was ideal.
