Did this hike 11/30/18, started around 10 am. Was beautiful. Spikes and poles were helpful to about St Mary lake. Went a little further but snowshoes definitely are recommended for heading up any further. I will definitely be back with my snowshoes!

Absolutely beautiful hike. I went early Friday morning and had the trail / glacier all to myself. I was glad I had my spikes and hiking poles. I was able to get quite a ways up the glacier. Snowshoes would have been helpful toward the top.

Beautiful. Trail is packed down at this time. Microspikes are helpful but probably safe without them. Beautiful.

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.

Snowshoed the North trail on 11-18-18. The road is deep with snow and chains are recommended to get to trailhead. We drove a Toyota 4Runner with big tires and made it, but our friends Subaru wouldn’t have made it without the chains. We had to pull three other cars out that were stuck.
We used snowshoes almost the entire way. Top is icy. Yaks trax needed. We got married on top with the most beautiful views of the surrounding ranges. Round trip in 6.5 hours.

Beautiful and easy hike. A bit uphill in the beginning. I was happy I had microspikes but snow shoes would’ve been helpful, especially if you want to explore around. It’s windy once you get there. A face cover would be wise to bring in fall/winter. Also was envious of the smart folks who brought sleds for the downhill back!

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.

amazing hiking, even in the winter!

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!

Summited 2009-08-01, with my lovely wife. We camped at half moon and then left right at dawn. It snowed the night before on the upper reaches. This is an easy Class I hike but still can be an ass-kicker. Poles are helpful. Exposure above tree line at 11k means you gotta be aware of the incoming afternoon storms in the spring and summer - you still have 3k vertical to go when you leave the forest. This hike will also throw you a few false summits, hahaha. Keep on trucking because the views up top are amazingly worth it.

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.

Great trail and beautiful views.

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

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.

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.

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.

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

Best short hike I’ve ever done. Don’t worry about getting lost. You are always able to see the visitors center from the dunes.

great hike, beautiful views, and a frozen lake.

Gorgeous little area, nice view from the top! Had my blood pumping but was still easy for sure.

Great short trail. My only complaint is there was a guy with a very noisy drone at the lake that he kept flying around for at least 45 minutes. Sort of took away from the experience.
