My husband and I hiked this trail today. We took Sunshine Trail that linked to the Lions Lair Trail. I am SO glad we started this way.
The hike down from Mount Sanitas should be rated as HARD. Knee high boulders all the way down. If you want to stay on a moderate trail, turn around at the top and go back down to Sunshine Trail. I was sure glad I had my trekking poles to assist my knees with all those rocks!

Fun trail! Nice views looking east through the Gulch. I took the short trail from the Hotel Ruins to the Continental Divide Viewing area. Short hike between those two points. There was a nice, steady incline all the way up.

Go West way up - beautiful and aerobic - great weather in am today

Huge fan of this trail; it isn’t easy, but it’s very much worth it. Spectacular views and scenery, and it’s not far at all from Boulder. Highly recommended.

Beautiful view with the snow and lake. Highly recommend spikes.

Spikes only needed on 3/17

Spikes are definitely needed, hiking sticks come in handy as well. Bundle/layer up for sure and enjoy the beauty that is Chasm lake, so worth the climb!!!

The weather was perfect (30 degree). Lake was frozen. Snow packed trail. Used trekking poles- no spikes, crampons, or snowshoes (although I’d def recommend spikes). Arrived by 10am and parking lot was already 2/3 full. Very, very, very busy with families, kids, visitors, etc. Since I’m from Kansas, the altitude always is an issue for me. Took my time. Fairly easy with a few slick spots- I was easily passed by locals with kids in tow.

Short bit difficult; went in March (3/14/18) and very icy. Made harder and less fun. Want to go back

An absolutely beautiful trail. We took it up to the Continental Divide Outlook. The views are amazing. There were a few icy patches but nothing to difficult to get through in normal hiking shoes.

I definitely recommend crampons/shoe spikes!! Very necessary. Very steep slick icy spots still, saw multiple people slip! It’s totally worth the incline up!!!

Hiked 2 miles of the trail. Liked the quarry.

Trail was very snowy and due to the past few days of wind the snow wasn't very packed. Super beautiful and amazing hike and there were plenty of people on the trail, but I would not recommend it without snow shoes

Hiked 3/13 with boots plus 30 lbs of camera gear, 20oz of water, a camera monopod/tripod/walking stick, and a MacBook Pro 15 (Which I regret carrying). Trail is mostly snow and very little ice unless you include the frozen lake. Great for first timers during all seasons. Definitely quite the winter wonderland and there's a fair amount of friendly people throughout the trail.

Beautiful lake.

Hiked 3/14. Great hike for people who are familiar with the outdoors. We hiked with just hiking boots but microspikes would have definitely been handy as the snow was a bit slick/slippery. Beautiful weather made it an incredibly beautiful hike. When we arrived at Emerald Lake it was extremely windy but we were able to sit and take in the majesty of the lake for a few minutes before we headed back.

3/14/18 - today was warm, about mid 60's, so there wasn't any ice at the top. A few sections of the packed show was a little wet and slippery, but not difficult at all. I had brought microspikes just in case and didn't need to use them.

Microspikes were definitely helpful, but snowshoes are probably overkill now. We had no problem making it to the lake with just spikes. The snow was only not packed down right near the lake

Bunch of switchbacks in the beginning. Very nice hike in the spring. The streams are definitely worth the complete hike

It is a good hike with views along the entire trail. There are many rock formations along the trail where people stop to boulder. It is pretty steep on the way up, but was more gradual on the back side of the mountain. The peak was fairly crowded, even on a Wednesday. Overall I enjoyed the hike.

Did this hike with my 12 year old daughter. Started around 10:00 am and it wasn't very busy. Got to the top and took in the view for a few minutes. Made it back down around 11:30 and it was considerably busier. Great hike, strenuous but not difficult. there was some icy spots (mid March) so be careful. Great day hike, I recommend it.

This trail was spectacular. We parked at the Brainard lot because the road was closed. Three miles to the trailhead, but pretty and easy. Once we hit the trailhead we slapped on our snowshoes and were on our way. Nobody other than a cross country skier was out there. The trail wasn’t overly difficult but we felt the hills. We’re doing it again end of March. Beautiful trail for snowshoeing.

Spikes definitely help right now, was able to take my 6 year old on her first hike with them. There is also a great rock outcropping to go up on one side of the lake. It has gorgeous views!

This is a steady elevation gain on the way to the lake.
Nothing that can't be done with some boots, but putting on spikes on the way down is ideal. These trails are great for carrying snowshoes with you so you can get off the beaten path during winter. Which is great because all the trails in this little area are heavily crowded with people. Crowded year round basically.

Great trail for beginners like myself! Can’t wait to go in the summer

Great views! Definitely recommend bringing spikes for some areas.

It was an easy hike except for the icy condition, although some other hikers had no problem with it, but I was slipping where there’s ice even with walking poles. The view was amazing, though! I’d definitely rent microspikes to wear next time. The lake is still frozen, I think the view will look even more beautiful if it wasn’t frozen.

Steady climb but easy pace and well trafficked. Nice reward at the top.

Icy, but beautiful & worth the effort.
