As a photographer that lives 30 minutes outside the west entrance to GNP, I would suggest visiting both sides, if not camping in both. The west side of the park has the tall glacier-carved peaks and lots of forest. The east has more waterfalls and open prairies. The Going-to-the-Sun Road connecting east to west is 52 miles long. If you camp on just one side for your whole week, you will traverse this or the longer highway 2 route many times. I would suggest splitting your stay equally between east and west.
We enjoy camping at the St. Mary Campground (east) and Apgar Campground (west) inside the park, but they are primitive. If you want more amenities, try the St. Mary KOA and West Glacier KOA. Enjoy your trip!
