We spent a week there last September, our 2nd trip. It has gotten very people friendly with the bus transports. We stayed in outside the park, in a campground in Columbia Falls. Not much of a drive to the park and we also enjoyed Hungry Horse dam and reservoir. A must see in our opinion. We also went outside of the western boundaries, where there is some campgrounds, albeit on gravel roads. Beautiful park, and certainly enough to keep you busy for at least a week. First time we went in early June, just opened GTTSR , lots of snow still. But did hike to the chalets. Second time, much older, but still enjoyed some hiking and the grizzlies we saw near Logan Point, and down by McDonald Lake. Always wanted to stay late in the season to see the eagles on McDonald Creek, just didn't make it!
