I'm doing a little pre-scouting for a visit to Glacier National Pk. I'm unfortunately limited to a visit between October and Early April so I'm questioning timing as well as lodging and perhaps camping or a short organized trip. I would also appreciate any info on side trips outside the park as well. My available time is unfortunately only a week and I'll probably rent a car after flying up from Fla so that cuts into the time as well unless I cash in some sick days. Thoughts?
