This was a great hike. Although steep in sections, this is more of a hard moderate than as hard hike on a good day. It was a clear day with no trail ice when we climbed it two days ago but the snow falling today.

Did this trail tonight after work with a couple of friends and our dogs. Really fun night hike! Spikes and poles would have been nice, but we didn't have them and were. Views of Boulder were gorgeous!

Microspikes required. I would not attempt without. I saw a few fall on their way down w/o trekking poles or microspikes.

Great trails! We went off the main path unintentionally, but the end result was the same. Gorgeous views. Definitely a tough hike!

We took a few off the path turns which led to beautiful colors of lichen on rocks and nice views of Boulder. Temperature was moderate with a few snow on the ground but crisp, cool air and sunshine.

Short but nice leg burn. If you want to get it in but don't have all day this is perfect one. Less then 2.5 hours while stopping a lot to take pics. Epic views are a perfect reward.

Awesome hike. Gets steep, but taken slowly is a blast. Dog was with me and she did great. Went right as the sun was coming up to avoid full weekend hiking trails.

Very crowded but great workout, short and sweet. Great views, especially if you go around behind.

More on the moderate/hard side. Steady incline but the short distance makes it easier. Perfect, quick hike!

I did the Flatiron Loop portion of this trail. Beautiful views, and not very difficult except for a few areas that required a little scrambling.

A fairly easy trail, with a bit of rock scrambling here and there. The views are beautiful and the trail is well marked. I would suggest trekking poles for those with balance issues or knee problems, and a can of Boost or comparable oxygen would come in very handy for those who haven't acclimated. I came from sea level and did the hike the day after landing, so acclimation was a bit of an issue for me. The oxygen really helped.
