I've only been in Kalispell for 4 years, so my info is limited. But depending on your vehicle a drive past Polebridge to Bowman or Kintla Lakes is highly recommended. You can catch some nice lake trout and cutthroats in either lake by trolling with spinners from a kayak or canoe. Both lakes see very little pressure, but leave Kalispell by 8 AM to find a parking space at either lake. Bring some very good bug spray. One of my renters works in the summer at Apgar Campground and spends a ton of time in the backcountry, and she really likes the eastern side of the Park closer to Canada, like the Belly River area. Don't expect to see a bunch of elk, deer, moose in Glacier. I've seen a few elk along the North Fork in the winter, elk near trout lake in the autumn, and whitetail/muley periodically around Apgar. The bears and wolves have made a pretty big dent on the cervid population, but you can see tame goats/sheep by the vistor center at the divide. It's an amazing park, and you will have a great time.
