We had family leave from Nashville and their flights were better through Denver, to Bozeman I believe, we flew from Indy through Chicago to Kalispell.The wife has been researching Glacier a few weeks so far, then will get me a list to whittle down and organize. I'd like to hit it this September, she's thinking 2025. I guess it depends on hotel / activity availability.
We will likely fly into Bozeman or Spokane, although it looks like flights and rental cars are cheaper in Spokane.
Going to the Sun Road was closed at the higher elevations.
We stayed in Kalispell the whole 7 days, and the SW entrance was a 45 min drive but required a pass to go up Going to the Sun Road at that entrance (unless you entered before 7). Not that great of hiking IMO at that end either.
The east side of the park was a 2-2:45 hour drive and you could get on the road. Much better hiking and viewing from that end, IMO.
We met quite a few people who spent a couple days entering the SW entrance and then moved over to the east side for the remainder, which I would highly recommend.
