I am spending a week in GNP in August, and will be staying in
St. Mary's most of the week and definitely want to go to Waterton.
I'm interested in short (under 5 mile) hikes and possibly the lake
cruise. Should I plan 1 or 2 days there, realizing, whatever time I take there will subtract from my time in GNP? Any suggested itinerary? Also, do rental car companies in Kalispell generally allow entrance into Canada?
