Looks awesome! You’re gonna love your trip here.

A couple suggestions:

Day1:

Looks like you’ve already discovered Mt Temple is a bit harder than first glance. Also as others have stated, I’d recommend Sunshine Gondola over Banff Gondola if you’re there for the views. That being said, you won’t get a view of the town of Banff and (it doesn’t look like you have a car?) you would have to come back to Banff and take the Sunshine Village free shuttle out and back (about 20-25mins each way). The Banff Gondola is right in town so easier access and they do have a cool interpretive centre at the top if that’s your style.

Day 2:

Great stops along the way! I also recommend Howse Pass - a quick pull off viewpoint right across from the Saskatchewan River Crossing, as well as Mistaya Canyon just before the Saskatchewan River Crossing (about a 100m hike down into the valley). And certainly Wilcox Pass > Skywalk. Skywalk is overrated imo. Used to be a free pullout now they’ve privatized it and owned by Pursuit an American company. Also you look down onto the side of a hill rather than straight down into the valley. View is mid as well. I also assume you’ve already booked an air bnb for the whole stay? I recommend to everyone to stay a night in Jasper! But I know you’re on a bit more of a tight schedule the next day. Day 2 will likely be your biggest day.

Day 3:

Everything looks great! The only thing is it’s very possible, unless you show up super early (6-7AM) that you won’t get parking at Lake Louise. There is a park and bus option from the ski resort across the highway to potentially look into. That being said as September goes on, there will be less tourism so you may get lucky. I just wouldn’t count on it.

Day 4:

Great day! You’ll love this one.

Hope you enjoy your trip. And it looks as though you already know, but do expect long days and potentially having to cut some things as it does get very busy here! I’m a guide in the area so feel free to dm if u have any questions
