Hiked this via the Highline trail from Logan Pass. The 0.6 miles from the highline trail to the Grinnell glacier overlook was quite the elevation climb, but very doable and totally worth it. Decided to adventure up a goat trail to a better view (also worth it), but did not continue south up the ridgeline of the Garden Wall. Stopped at the Granite Chalet afterward, and then followed the Granite Park Trail back to the Loop. A rewarding day to be sure!
Turned out to be a great day inspite of not reaching the original objective.
