I am looking for help with an itinerary for a Glacier National Park. We have never been. It’s a little bit of a late minute trip - I know I might have a problem finding reservations( hoping to get in on any cancellations) but any ideas would be very helpful. I will be traveling with my husband and our three children ages 18, 14, and 3. We will be leaving from Yellowstone National Park on Wednesday, June 27 and driving up to glacier. We have about four days to explore the park until we fly home from Spokane on Monday. My first question would be should we drive to the east end of glacier or the west end from Yellowstone? And should we add Waterton to the itinerary? Also can you cross into Canada with only an enhanced drivers license or do you need a passport.? A coworker of mine has suggested that the views from Waterton area are magnificent. Also as far as hikes go, what would be the best family hikes with the 3 year old?
