We're finally getting to take our first vacation in 3 years (since the kiddo was born.) Any advice on activities and must-see's in Glacier National Park and the surrounding area? We've already got plane tickets and have 2 nights at a lodge on the east side of the park and 4 nights in Kalispell, MT for early August. How is the trip back and forth each day to the park from Kalispell? Any helpful information would be appreciated!
