spend at least 5 days on the Bow too. Don't miss out on those fish. Not quite secluded, but the lower bow r valley has quite a scenic appeal, it's a wonderfull river full of fish.
others to hit
N Ram,
Red Deer
Crow
Oldman
Livingstone
If I were you I'd slip into BC and try some of the Elk R , and tribs there... only 2.5 hrs from calgary.
