We have stayed in Glacier NP's St Mary's campground on the east side of Glacier. It is close to the park HQ and is typical of a NP campground with smaller Aspen trees as I remember. Last time in Glacier we stayed in the Fish Creek campground on the west side. Again, a typical NP campground but is among tall pine trees which were to our liking for shade.
Can't speak to any commercial campgrounds there as never used them.
Happy camping there as Glacier NP is a favorite of ours!
