Really enjoyed this hike and was very challenging!! Once I reached the base of Andrews it was hard to find the trail!! I went up the middle which was not the best route but it was tracked by others. Many boulders and very difficult to find the beaten path so pick a line and go!! Made it to the Glacier it was pretty amazing and thank god there were a few experienced hikers of this trail on top top show me the best way down. Would like to try again and summit Ottis!!
