We would be visiting glacier NP probably from August 10-15, thanks to free flight tickets. We would be flying into either Great Falls or Missoula, reaching glacier on 10th evening and would be leaving by 15th noon. Could someone help us by pointing us to a good itinerary? We love to hike, photograph etc. Also could you tell us cheap accommodation within and outside the park (as required by the itinerary? We are nature lovers travelling on a very limited budget. Any help is greatly appreciated.
