If it were me with two weeks to give, I would take a few days and route myself out to the Eastern side of Glacier, drive north across into Alberta, Canada - WATCH OUT for roaming horses and cows around every corner!! The must see visit is to Waterton Lakes National Park. It is simply outstanding. Canoe/kayak on a glacier clear lake, see loads of bears and high tea time at the Prince of Wales Hotel. Quite the experience! Had my mother and two teens in tow and loved it! Beautiful scenery on up north through Pincher Creek (Hwy 6). Route yourself west on Hwy 3. You'll find some great coal mine tours and one of the Alberta's deadliest landslides (still visible in the town of Frank). Then you'll pass through Crowsnest on up to Sparwood - gorgeous scenery! From Sparwood, Hwy 3 turns south. Connect on to north Hwy 93 in Elko and then you'll head back over the border at Roosville and find yourself back on the west side of Glacier National Park.
To be honest, we did the route starting in Roosville going in reverse and the scenery was spectacular. Either way, you would love it!
