Wouldn’t say is hard- solid moderate. Short. Trail crosses rock slide which is fantastic. Trail takes you to back of first flatiron, which cool, is bit of anticlimax...

When I go to Colorado, I get excited thinking about summiting this peak. I absolutely love this trail!

We hiked with a five and ten year old with light snow on the ground and it was awesome.

Beautiful trail. Not as easy during winter due to no sun. snow takes longer to melt causing the trail to be muddy and icy in some places.

beautiful easy hike

cool. nice views.
a lot people trail running, so might be good for that

easy breeze hike. nice views.

windy at top. amazing views.
nice cool hike

Difficult & steep trail run, but well worth the efforts

Climbed 11/10/18 - Sanitas generally stays drier and more snow free compared to nearby mountains like Green or Bear which makes this a great mountain for a workout hike or trail run. Quick and easy. Always seems to be more crowed than Green or Bear. Views from the summit are only of Boulder and you cannot see anything west:(. Additionally the summit block is small and crowded which was an annoyance both times I climbed it. So this is a great workout mountain and is fairly fun but the views and solitude are lacking compared to neighboring mountains..

Going counter clockwise on the trail was a bit difficult, the trail was tricky at times. Unfortunately I went on a cloudy day but if you are looking for a trail to get a sweat going this is a great one.

Did this trail when first visiting the area..definitely was a little challenging on the way up! Was a great workout and the view at the top is awesome.

This was a great workout. The views are amazing. There is lots of stairs and boulders to go over. A bit missing and icy on the back loop going down.

beautiful peak, but tougher than expected. saw a lot of other hikes even though the weather wasn't great. I'd probably do it again though!

Amazing hike with good technical areas. Go in the snow if you really want a good challenge, but to get to the peak you’ll definitely want trail spikes. Lots of trails to link onto too. definitely one to add to the books!

Really great views of Boulder. Definitely an asskicker at times, though not always. Trail was in good condition, with lots of people taking advantage of perfect hiking conditions.

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

Visiting Boulder from New Jersey, and a few hours after landing my friends and I did this trail. Absolutely stunning scenery. Easy enough considering we are not used to the altitude. We decided to go farther and do the Chapman Dr trail which loops back into the same parking lot that we started for tenderfoot! Nice little hike with beautiful views, I would love to do it again!

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.

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

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.

lit trail, scaled the face

This hike will probably take longer than you think. It is quite steep. Views at the beginning are expansive, the middle section is a tough climb in the trees with few views, and the end section once you gain the ridge has views back towards Boulder and also east to the Indian Peaks. From the Bear Peak summit you can probably pick out your house if you live in Boulder, the view is that unobstructed.

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

Great hike.

A standard for a quick trail running workout in Boulder. Have encountered mud and wasps on the McClintock section in spring, but overall good conditions especially in summer and fall.

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