This trail is not MODERATE but HARD. I used this trail guide for our hike. When we finished I looked it up again and found another Arapaho Glacier Trail same trailhead, that is listed as HARD. Don't be fooled, this is not MODERATE. Great hike but hard even for us. Lots of rock on trail (feet sore) and steep incline all the way to the top. Weather changes rapidly, take rain gear. Can get very windy once above treeline. Steep/rocky terrain. Great adventure but hard.
