This is the most difficult trail I have ever hike until now. The trail is nearly 70% REALLY UPHILL so have prepare for that. It is really cold in this trail and SO MUCH windy so it can be dangerous if you not strong enough. This trail is interesting because I go through a snow path and the scenery is so beautiful. This is 10000 ft so after 8000 ft the air is thin and make you less oxygen and difficult to maintain the breath , be ready to have a good health. There have a path that dangerous because 2 side is the abyss , the strong wind and you can fall down if you look down and have decease relate to the height. The way to go down is easy because it is always down hill.
