My Son is very fortunate to work at Glacier, and I was very fortunate to be able to visit him last August. OMG, it is beautiful. He lives on the west side in the park. Highly recommend the Crown of the Continent tour on the red bus, leaving from west Glacier going across Going to the Sun road to east Glacier. We also did the zipline at Whitefish Mtn, the 7 zipline was awesome. Your teenagers would love that. Also, went on a rafting trip with West Glacier Rafting, would recommend them. Although, I was staying at a lodge, I made him drive me through the KOA in West Glacier, it looked very nice and close to the west entrance.
