Tough trail for beginners. Definately a good workout. This is also a very popular trail.

A fantastic climb with a great summit.

Great trail and beautiful views.

Beautiful trail with some nice views near the top. The Flatirons are really cool-looking peaks! The trail is really well maintained and manageable to walk on, even during the steeper points. Lots of switchbacks toward the top made the ascent easier than I anticipated. Only one very brief scrambly section.

We stopped at the very top of the second Flatiron (the trail seemed to peter out a few meters behind it) and came down via Bluebaird Trail. Passed lots of other people in the morning, but no congestion.

Amazing fog this am with snow flakes. Trails dry with friendly people and amazing views. Happy Thursday m8y's Oiiiii

Short and steep, a good workout, with some good views. Not so crowded, but it was a weekday in early November.

great hike. took the kids 3&5. I would say this is a moderate hike only if you are doing the final climb to see the cave entrance.

Awesome hike. Not overwhelming hard but tough for moderately in-shape folks. Mostly climbing steps. Gorgeous view at the top.

Great hike! 'Moderate' rating is appropriate. Signs and trails can make it a little confusing at the beginning, so following the mesa trail signs not the ncar trail signs. It's a pretty steep hike in general. 2.4 miles OUT and 2.4 miles BACK. Last 100' was too steep for our group of 2nd graders. Beautiful views amongst the flatirons. Still worth going even though we could see the cave at the top.

Lots of steps up (45 min) but worth the reward. Easy hike down.

Trail was not super tough. I would highly recommend using spikes. I did not and was fine. Just watch where you’re stepping. Though my wife did use spikes and said she felt much more comfortable coming back down. There was an incident with a dislocated hip. Not sure if it was from a fall or whatnot, but it is better to be safe than sorry. As you get further up trail you run between dry land/rocks and icy areas. The end is def worth the hike up. Just be careful!!!

Awesome hike. Leg burner for sure!

Great views of Boulder. Decently trafficked by people and easy to find the trail. Around the peak it does get pretty rocky so good shoes and sure footing is highly recommended. Haven’t hiked in awhile and did the loop in a 1 1/2 hours with a longer break at the top.

Gorgeous trail. Strongly disagree with the "hard" rating-- it's difficult for a relatively short period of time, so I think it's more in the moderate category. It was actually rated moderate on alltrails until about a month or two ago.. not sure why it was changed.

This trail is short, energizing and has better views than some of the even harder trails in Boulder.

Good, easy hike - little surprised to see it was moderate. Nice views! Only negative was a good chunk of the drive up was unpaved, and it had rain/snowed so an unanticipated muddy car.

This hike was amazing. The first half was very smooth and simple, then it turns pretty rocky for the last mile or so. The very last bit was absolutely the best part though. I saw other people posting that the last 100 feet or so was a climb, so I was expecting something along the lines of boulder hopping. Boy was i wrong! It was a legitimate climb! I would say it was about a 60ish degree angle, which was exactly what i was hoping for! Most of the trail is great for most dogs, and older kids too! I will 100% be going back!

Beautiful trail. well maintained and not much traffic on the trail today because of the cold may be. But the parking lot is full as there are lot of trails starting at the same place. I have parked on a close by street. It snowed a bit while I was there and it was beautiful

Gorgeous, nice short walk with some stairs.

Fun dirt trail through many cities/neighborhoods of the Front Range. Good views of the mountains and nice terrain to keep a good pace.

If you are going to do this hike as a loop , I would recommend going up Mount Sanitas and returning Sanitas Valley .

Great hike.

My favorite trail in Boulder. I do it several times a year in all different seasons. Traction is definitely a good idea in winter. Can be crowded. It is steep. But I still love it. On clear days, one can see out the expansive eastern plains, and the city of Denver in the distance appears very small and isolated.

Great local hike. Lots of doggos on the trail enjoying the best of life.

Great trail! The last 100ft up to the cave is a pretty steep climb up rocks... not very kid or dog friendly, but the trail leading up to that point is great. Definitely recommend boots.

Pretty awesome hike close to home.
