Our loop though the Kootenay region last year was very nice.
If looking for an out of the way place, from where you can access spectacular alpine hikes, take a look at some of the hikes into the Purcell's from the west side, base camping at Duncan Lake.
I suggest that you get the book, "Where Locals Hike in the West Kootenay" by Kathy and Craig Copeland.
Another book that you might consider is "Mountain Footsteps - Hikes in the East Kootenay of Southeastern British Columbia" by Janice Strong
Have fun,

p.s.; maybe your wife would like multi-day rafting or canoeing as there is no pack to carry?
