it would be 37, sentinal pass but you don't have to go up the pass. I have taken out of shape 50 year olds from ontario up to the meadow.
Parks Canada - Trail Report
that is where the trail conditions are, looks like it will have some snow, you can call and ask if the meadow has snow. It will also tell you if there are bears in the area. I would get and bring bear spray anyway.
I don't' think you need any climbing experience to get to any of the huts although climbing is fun so take the course anyway.
