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.

This hike has incredible views and is a lot of fun. After you get above tree line it’s a steady but moderate march to the summit. Well worth it !

Amazing trail, this was my 3rd time on this trail. This was the only time that I didn’t go in summer, the conditions were snowy about 2-6 inches for about 5 miles. After it began to get deeper about a foot and approaching the scenic mountains it began to get frigid with windchill below zero. At that point I descended my journey back to the parking lot

We started early morning: around 5:10AM, still in the dark from Rainbow Lake Trailhead, close to the campground. That turned out to be a great idea: as we climbed higher and higher we were greeted with awesome views of the horizon painted various orange/red/yellow colors as the sun was rising. Also saw from different spots Boulder with its lights still on, so great early morning views.
Then the light rain started, which pretty much stayed with us the entire time. Occasional windy spots, such as at Arapaho Glacier. With being wet, the occasionally strong wind was definitely not helping.
Despite of the steady, but light rain, still enjoyed this trip very much! The views with the clouds moving in and partially hiding the surrounding peaks, provided for unique views.
Except for a short section where we still had to go through a snowfield (easy, no issues), the trail was clear from snow, but wet. As we were descending to Arapaho Pass Trail, the lower we got the more often the trail went through thick patches of bushes. Amazing, how much water those bushes can hold: each time felt like taking a shower, so there were not many dry spots on our clothes. Shoes and socks were already dripping wet.
The solitude this trail provided with the light rain was very special and very relaxing, so completely didn't care about being wet, but more enjoyed our time...
With the elevation gain, it is a great workout and the trail most of the time is single track. Above tree line it is very technical, so if you want to work on your foot work and cadence, this is the route for you... :-)
