I’m not exactly sure if you are supposed to go to Glacier Falls.  There were some trees across the trail (if you can call it that), but it was certainly worth it.  Glacier Falls is after Alberta Falls and on the trail towards Mills Lake.  Alberta Falls is below Glacier Falls on the river and I believe Alberta Falls is after two smaller rivers come together, one of which is Glacier Creek.

If you do not have a pretty accurate GPS I believe it would be really hard to find the cutoff to Glacier Falls.  On the trail to Mills Lake, about 2.3 miles from the Glacier Gorge trailhead there is a little cutoff on the trail.  The trail that you are on is an “improved” trail, but the Glacier Falls trail is just a little cut.  After you cross a stream on a man made bridge you will go around a corner on the trail with some man made steps and the cutoff is right there.  After that, follow the small trail or follow the sound of rushing water.

The falls themselves are a lot like Alberta Falls; however, it was completely secluded and unlike Alberta Falls with its big granite boulders, Glacier Falls is surrounded by the trees.  You can get right up to the falls and sit on the rocks near the falls.  Glacier Falls is a cascade that falls about 30 feet total.  It is definitely worth it to try and find this one.
