Full disclosure - I only hiked like 5 mins of this trail, but that's because it was closed for the winter still despite being Sunday June 29! The trail actually opened in full that Wednesday, so I came just slightly too early. That said, I hiked the loop trail up to the intersection of the highline trail, and walked along to near glacier junction. You can see the continuation of the trail in the distance and it is obviously a gorgeous trail - and quite challenging given the distance, although I'm told the incline is actually fairly gradual. Overall: I'm planning a trip back to glacier next summer a little bit later specifically to do this trail out to grinnell glacier overlook along the garden wall. My trip along the loop was absolutely stunning, so I want to make it out to granite peak chalet again another way. And while it likely won't come as a surprise to anyone planning to hike this trail, do bear in mind the warnings about safety including taking enough water/food, bear spray, and ideally going with someone else (particularly given doing this trail takes pretty much all day). read more
