Great trail. Very busy. If you are bringing a dog you should know that it is sketchy in certain sections.

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!

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

This is my go to trail! You get a great view at the top and there’s a metal plate that shows you all the mountain ranges to the west at the top! It starts off easy but gradually gets harder.

Trail was very nice. Some ice but you can get around it, also Mud. Towards the end there are rock stairs, so there is a bit of a climb. The summit was very nice, not amazing. Small area once you reach the top so if it's a busy trail day, it will definetely be crowded. I only gave it 3 stars because the summit view was not that impressive, the trail itself was very pretty.

This Red Rocks to Anemone trail is closed off at the Centennial Trailhead, accessed from Mapleton Ave as it's turning into Sunshine Canyon. Postings said it was supposed to open in February. (I'm told you can get on the RR trail from Settler's Park.) Probably 12 parking spots in this lot. Instead we took the Sunshine Canyon trail (easy, narrow trail) and then crossed the canyon to get on Lion's Lair.

Beautiful views, lots of fun. Brought our dog and he loved it.

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.

Stay on the trails for an easy walk with awesome views, or climb around on the rocks for something different. The whole family went on this hike and everyone enjoyed 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.

Easy hike with rewarding views. The trail was a bit icy in some spots but overall it was in good condition.

Not so much moderate. More hard. Approaching the loop and heading to the right you have a slight grade for a mile which is deceiving. Boulders ahead! Pretty challenging for me and my Cattle Dog.

Love it. Multiple trails to chose from to vary intensity

Mar 2 2018. Fun trail. Crowded but not too bad. It was icey and wet but manageable

Very popular, mostly college kids and we were the oldest at 64 yrs. However I would not say it was moderate at all, but hard! High stepping up log”stair master “ and mostly knee high boulder climbing. Pretty views and really nice at the summit. Two hrs up and one to get down for us. Big wind gusts and temp drop coming down, but sunny. Ran into two rangers who said this should be labeled hard. Many dogs, so that’s always a plus! My dog loved it and worn out today! So if you are older with compromised knees, it will kick your butt. But we were proud to finish! Didn’t go down the other side as heard it’s still icy/ loose gravel in that side.

We only did a portion of the hike. The wind picked up and it got to be a little much. I would definitely go during the week. Parking was full in the lot and we had to park quite a ways down the street so that is the only reason for 4 vs 5 stars! I will be back to do the whole loop!

Icey but beautiful!

One of my favorite hikes of all time, but difficult to navigate due to snow unless you go in July or August. Absolutely gorgeous. The little lake at the top is quite a climb but worth it.

Gorgeous. You absolutely need snowshoes. The road to the trailhead is closed so tack in another 6 miles rt. Awesome trail. Nobody- other than us and a skier out there.

Very crowded on the trail but I went on a clear day. Be careful going down the mountain as there was still plenty of snow and ice. I managed just fine without spikes but it would have made it a lot easier with them. All in all, absolutely amazing hike with a view that makes walking straight up for 2 miles feel rewarding.

This was a nice trail, super icy today! It’s definitely a workout climbing up and around all the rocks but worth the view from the top. My dog had a great time running around too!

I ran Mt Sanitas today. There was minimal ice and even where there was ice, there was enough trail to go around. The sun was welcome as it warmed the body coming back down. It was a bit windy today, but not too bad.

Busy on the weekends but it’s a good hike. Not really any spots where dogs can’t make it. Be careful of ice along the East Ridge Trail though.

A good workout, and great for bringing the dog!

Excellent hike with our dog. We took a lot of breaks and we finished in 2.5 hours. Lots of people, but all friendly and respectful. There’s a small patch of ice near the halfway point on the valley side of the trail. We saw a lot of people fall and one woman broke her elbow so BE CAREFUL at this section! Other than that, a wonderful afternoon hike.

The view was absolutely beautiful! For others it may be meh, but this was my first hike. It got pretty steep and rocky towards the top. I had to stop plenty of times because I didn't bring my inhaler. Definitely worth it! I went in November!

Great trail, beautiful views. The trailhead is just outside the flagstaff pay parking area. I went on a Friday, late morning in early February. I could see how parking might be an issue on a busier day. I didn’t give it 5 stars for two reasons; first a good portion of the trail was covered in ice. Not really the trail’s fault. If you visit in the winter ice could be mildly annoying to a bit dangerous. Be prepared! The second reason I only gave it 4 stars is the hike is fairly easy! If feels like a stroll through the woods with a few sets of “stairs” thrown in. The views are quite lovely - but I like a bit more challenge to “earn” those views! The trail is dog-friendly but dogs must stay on leash for most of the trail (even if certified with Boulder County to be off leash). The day I went the whole Front Range was blanketed in a cold fog. But this trail was above the fog line. The trail was sunny, warm and there were great opportunities to see the blanket of fog covering Denver and Boulder! Magical! Overall a very lovely “spa day” hike!

Patches of ice on the east ridge close to the summit. I was in running shoes and didn't have a problem crossing.

It’s a fairly easy trail for anyone in good shape. Some stairs, some flat, overall a well constructed trail. Nice mixture of pines, rock structures. Good views from peak. In winter you can see Eldora ski runs to the west. I personally enjoy this trail a lot.

great 50 degree day in boulder! no ice on the way up. slightly icy on the loop down, due to lack of sun.
