The definitive Boulder workout. One of the first to try if you are only here for a short while!

This was my first 14er. I chose this for my birthday and did it 10/19/18. I did not complete it because I underestimated the snow and attempted it 24 hours after leaving an elevation of 10 feet above sea level. I made it to 13,523 in about 6 hours and back down in 3 hours. I had to turn around because I was going alone and I left a deadline with friends and needed to make it back before they sent a search party. I will do this again in June after acclimating for a few days.

I had 4wd so I got to drive to the trailhead at 5:30am. I met 3 young men walking up the road and gave them a ride and learned they had just flown in from Miami a few hours earlier. We all struck out at 6am but they turned back after realizing they were too tired and in no shape to hike. I learned it is really cold at 6am there, I still have fingertips that tingle.

I learned a lot and can't wait to do this again when I am a little more prepared. The mountains were beautiful covered in snow but man that snow sucked to walk in. I questioned myself all the way down then decided I was coming back to conquer the mountain as soon as I could.

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

Beautiful trail but as previous reviewer mentioned, at some point near the end, the foot path in the snow deviates from the actual trail. I had a GPS with me so was able to figure this out (coupled with clues based on the trail just not seeming right). We never actually made it to the lakes but the hike was still beautiful. I would say if you don’t have a GPS, be careful as just following the footprints in the snow isn’t actually the trail & gets a bit sketchy.

Beautiful short hike although it does get crowded. Everything was frozen over and we walked across the lake. You can get some beautiful photos up here! Hiked in November and microspikes were definitely helpful.

Trail is all snow, most packed by skiers. Final ~1/4 mile to the lower lake is unpacked snow (unless we took a wrong turn, we were definitely off trail on deep snow following footprints).Great hike but with the current conditions if you don’t have snowshoes or skis you won’t make it all the way up.

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.

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

Good trail for all age groups. However, it’s a bit rocky but that should be fine. Took us 2-2.5 hours from car to car including breaks. The views at the top are pretty good and picturesque. Would highly recommend during fall season.

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.

Beautiful hike with lots of lakes and pretty views. Hiked this back in September. Saw mother and baby mountain goats. Not too many people on the trail, but definitely some traffic.

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.

Hiked this 3 weeks ago and needed crampons to make it to the top. There are two ways to make it to the lake. One of them requires a rock scramble; but both are a steep climb. It's beautiful country and worth hiking it in the snow.

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

lit trail, scaled the face

sick trail

large crowds, leg burner, beautiful trail and views

Went in early October on a cloudy day and got some snow near the top. The lakes were incredible though. Lost the trail on the way to the furthest lake, and ended up doing some rock scrambling that we weren’t prepared for. Saw a moose alongside the road on the way to the trailhead! Def want to go back on a clear day.

The views were incredible, but the trail itself was not very well marked (except for the trailhead). We were essentially just following footprints in the snow, and at one point reached a fork in the footprints. We decided to follow a set of footprints that ended up taking us off the trail, and into very deep snow drifts. Microspikes aren’t necessarily required, but waterproof snow boots and multiple layers are essential. It gets very windy up there!

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 hike! We went last Friday and it was a beautiful day. The trail was icy and snow packed in some areas and even more so the closer we got to the lake.
