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...

hiked early morning 12/9. The hike to mills lake is a nice boot pack, crampons or microspikes reccomended. After mills lake, the trail mostly vanishes and its time to pull out the snowshoes. Great snowshoeing out to black lake. The views from the frozen lakes are astounding. Mild crowding on the way out to mills, very few after that. I would highly reccomend this trail, be ready for some pretty exhaustive snowshoeing the second half.

First time hiking to Black Lake in winter. Trail from Bear Lake to Mills Lake was perfectly packed down, microspikes made it easy. The lake was frozen solid and it was so cool to walk straight across! Softer snow between Jewel Lake and Black -- changed to snowshoes about 20-30 min before reaching Black Lake after post-holing a few times. Luckily there were clear ski/snowshoe tracks to follow all the way. The distance between Jewel Lake and Black Lake always feels farther than it actually is. We walked around the shore of Black Lake to continue snowshoeing up to Blue Lake (used a GPS watch because we didn't see signs of a trail). SO worth it! The views from above the lake were stunning. Even better, Blue Lake was sheltered from wind making it a perfect spot for a snack break. Will definitely come back in the summer to find Green/Frozen and climb the Spearhead.
12.5 miles in 6.5 hours roundtrip

On a beautiful Sunday, it was relatively calm and I had the trail to myself for large portions of the trip although traffic increased toward late morning. Packed snow after the final creek crossing and used traction for most of the ascent. Removed for the downclimbing rock scramble 'cause the rocks were clear then put them back on for the last portion to the Arch. Repeated on the descent.

Beautiful day, perfect for a winter hike. Plenty of fresh snow, animal tracks, and evergreens. First mile and a half or so is well packed and I did just fine with microspikes, but snowshoes would be better for the rest.

I did not finish the hike due to the last half-mile out being past your knees. It was beautiful but at times I was too hot or too cold with how I was dressed. I passed two dummies that were walking around in Boots and jeans and were covered in snow up to their hips essentially punching holes in the ground with their feet and ruining the blazed trail. Please do not do this. this ruins the trail for everyone who actually planned ahead and knew when it snowed you should bring snowshoes.

I went to hike this yesterday morning/early afternoon (12/7/2018) and the road we came in on was closed about 6 miles out. I did not try to loop around to the west nor did I head back east to go over and up and see if that pass was open. Beware.

Completed this hike (+ a little extra) with my girlfriend in late summer. We did not set out with a definitive plan...got a late start, around 10am. We attempted to reach Green Lake after Black Lake, but turned around halfway (around 11,150ft) due to approaching storm clouds, and wanting to be back before dark.

Hard is an accurate rating, especially the last half-mile to Black Lake, and the extra mile we did after. I'm in moderate shape, and my girlfriend was visiting from sea level (her first hike above 10,000 ft!). We took a fair number of breaks for snacks and pictures...our Fitbits said 12 miles, 36,000 steps, in ~9 hours. The hike itself was not daunting, but we were exhausted by the end, and sore for a few days after.

Top pros were that the views were spectacular, and that the trail was mostly well marked. The exceptions are that we never saw the turn to Shelf Lake and Solitude Lake. We also completely lost the trail in the bolderfield between Black Lake and Green Lake, which contributed to our decision to turn-around.

The biggest con, and reason for not giving it a 5th star, was the heavy traffic up to Mills Lake. We even got stuck behind a lady talking on her cellphone for awhile. We chose to skip a number of attractions (i.e. Alberta Falls) to avoid, and try and surpass, the crowds. Fortunately, most people stopped at, or before, Mills Lake. We saw less than two dozen people between Mills Lake and our turnaround.

Overall an excellent hike that we hope to do again, next time with an earlier start, a better plan, and hopefully in a little better shape!

Awesome hike!

excellent trail. nice quick easy hike

Once you have the pamphlet the trail is very easy to find. Recommend doing this hike for sunset, it was beautiful and not a very large crowd. Will need some flashlights for the route back as it can be easy to lose the trail.

My husband and I did this hike yesterday afternoon. We were surprised to see only two other cars at the trailhead when we arrived a around 12:30pm. We saw two hikers on the way to the lake and then had lake/waterfall to ourselves. I thought for sure it would be crowded and was happy to be wrong. The trail was snow packed. Visually, it looked like a winter-wonderland. The trees were lightly dusted in snow. We both had our yaktraks on and I was thankful for them multiple times throughout the hike. Definitely some slippery spots, especially on the way back down.

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..

Climbed 11/18/18 - Absolutely gorgeous from start to finish! Quick and easy. West side of Green mountain definitely holds more snow than the east side so the whole route is snow covered and beautiful. That said, it's so popular that it stays boot packed. The last few hundred feet to the summit get steeper so I'd recommend microspikes for extra traction this time of year. Enjoy!

Completed Black Lake 11/28. Traction was nice to Mills, not necessary. Flotation was necessary after Mills. Trail was not difficult to follow despite being faint from wind. Last .7m added a few tricky spots weaving through the creek. Not enough snow pack in some spots to keep from post holing, avoidable with attention. Skis would have been great.

Love this hike! Did it in 1.5 hours with crampons - highly suggest them! There were a couple people with just boots who made it, but it looked difficult. Had the lake to ourselves :)

What a sunset spot! You have to check out this arch close up it is really something. Walk isn’t too tough and trail is easy to follow with trail markers along the way. Toke us about 40 minutes to the top and 30 mins on way down. Was pretty busy even in mid November but a most do if in arches. Plenty of parking and toilets at the trailhead.

Great Hike. It’s worth the climb to the top. Be careful there are some slick spots. We did this as a family. 15 & 13 yr olds handled it well.

Great hike summer or winter will need spikes for sure

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.

One of the most popular hikes in the park and there is a reason. It’s a pretty high elevation gain over the 1.5 miles so take your time as you are going up. Plenty of places to stop and rest along the way. Once you are almost to the top there is a pretty small ledge that you walk around so those with heights might have some issues. Once you make it it is all worth it. The view is amazing and it is as spectacular as all the pictures you see of it. Make sure you take water and headlamps if there is any chance you are coming down in the dark. Kids loved it!

been there twice last 2 weeks.
bring microspikes. it will make your hike safer and easier. by the end is windy, amazing views. few people hiking it in November.

Awesome and easy hike! If snowy definitely come prepared because my friend busted his ass 6 times

Great hike! Yaktraxs are an absolute must as a majority of the trail is covered in ice. Make sure you take your time; we saw some people slip and fall and it’s easy to get hurt. Although they weren’t wearing spikes those that were were still using caution. It’s well worth it once you get to the top!

Easy, beautiful views, and close to Denver!
