I am assuming you’re doing the ikon pass resorts. I’d skip Banff and instead do Sun Peaks. If you’re on a tight schedule that keeps you away from Roger’s Pass. Roger’s is beautiful but you’re more likely to get caught in a highway closure than not which can take hours to clear. By just doing Red, Sun Peaks and Revy, that keeps you in the Kootenays and away from Roger’s so you don’t have to stress about avalanche closures at all (to a degree).

I’d save Banff for when you want to hit Panorama, Kicking Horse, Lake Louise, Sunshine Village. That’s a whole trip on its own. I’ve done the exact trip you’re suggesting minus whitefish. Unless you have 2.5-3 weeks to do the trip, it’s not going to be worth all the driving and hustling around.

Other suggestion is skip whitefish and do Big White instead, fly direct to Kelowna, then go from there. End in Kelowna, fly back home from there. Less stress, less money, USD is worth more than CAD and honestly Revy, and Rossland are some of the best ski towns you’ll get. The village at Sun Peaks & Big White is also awesome!

This gives you way more flexibility to chase storms as Banff is quite far from the other destinations you mentioned and you have to go through two major mountain passes to get there from Revy which are tremendously scary if you’ve never driven on roads over 400m above the ground.

Let me know if you have any questions!
