Excellent trail! we did the first leg to the peak about 3 miles. mostly open until you start the climb. Climb was challenging over rocks, right turns. Peak had amazing views. Took Lion's Lair trail back down and this leg was mostly paved but a long 5 miles or so. Overall a really nice park in Boulder with several interesting trails.

you walk along side a lake up to another lake. a cool and easy day hike with great views.

This is a short but challenging hike. Great views along the way and at the top. The hike up will get your heart going. The hike down seemed almost as hard, especially on the knees. There are lots of trails in this area. Pay careful attention to your route to the base of this trailhead as there are several that will bring you here.

nice quick hike up to the lake, not too challenging. awesome views at the top with a second lake if you continue which we didn't have time to do. the road up to the trailhead is very rocky so be careful driving. highly recommend.

Definitely listen to the other reviewers and drive to the lot at the start of the trailhead! Also, don’t forget to continue past the second lake up to the third! The view is so worth the climb and you’re practically all alone at the lake. Great spot to enjoy a picnic lunch.

This trail is rated difficult for a reason. Tons of large rocks and quick elevation gain. If you have balance issues or are afraid of heights I would say don’t do. The views at the end are fabulous though, great workout! Beware of small area that would almost qualify as rock climbing and not hiking although once you got up wasn’t that bad because of the hand and foot holds they added. Fairly heavily trafficked trail also..

Did this trail in midJuly with an out of towner (from sea level) who had a tough time adjusting to the altitude change. We AWD our way up to the trailhead which was very rocky but doable in our vehicle. Beautiful wildflowers. First lake is pretty, can’t get to it d/t private property, can see almost the whole trail. Second lake was a bit of the way up, more closed off but beautiful. My visitor didn’t want to try for the third lake so we turned around and headed back.

Very nice!

Great hike awesome view from the arch. steep in places and rocky. worth the trip.

I have used AllTrails for a long time, finally purchased it - just saying, why did I wait!

I did this trail today. I was impressed, given the use it gets, how clean it was. Around the trail head and at the lakes there was no trash. It gives me faith in outdoor humanity. It is a lovely hike. Good for young hikers.

Great trail, hard climb, worth every step

Nice hike, great views at the top!!

beautiful, moderate hike, very crowded on the weekends. recommend arriving at trailhead before 730am. diamond lake has plenty of space for the masses but is busy by 930am. recommended!

Quintessential Boulder hike. Went clockwise today - I prefer to tackle the big “steps” on the ascent and come down through the valley. Always nice to have bathrooms (across the street from the trailhead.) Friendly faces and interesting terrain. A perennial favorite.

Great hike! Definitely not too difficult... fairly trafficked on the weekend as of you approach the Lake. Lots of fun waterfalls and little features along the way.... If you’re doing this on a weekend definitely make it to the trail head by 7-7:15AM or you’ll be in a jam to find parking! We made it at 8 and parked about a half mile down!

Hiked it on a weekend and was not very crowded. We parked just past the point where the stream crossed the road and the hike was 7.5 miles round trip (from car to the lake and back). Very pretty hike, very challenging. Would recommend it.

Great trail. Lots of climbing on the way up, but it’s all worth it for the views at the top. Go early to avoid the crowds – it was already pretty busy at 7am and people were lined up inching along the narrow paths on on the way down. Free parking is available about 10 blocks away.

Great views and a well maintained trail. We drive our Outback up to the trailhead parking lot no problem. Few spots where good driving was needed due to drainage ditches. Wouldn't want to take anything with lower clearance than an outback though. Started hiking at 0830 and saw only a handful of hikers. By the time we were done, the lot was full and the trail was quite a bit more populated. Totally worth the hike though!

I give this hike 3 stars in the summer and 5 stars in the winter. It's a great location, just over an hour from Denver and you get to go through Georgetown and past Idaho Springs which both have fun food/drinking options for post-hike. For summer, the hike is easy/moderate and isn't terribly exciting - ranging from 4 or 6 mi round trip depending on if you're able to take the AWD road or not. People mention wildflowers, but compared to most other hikes in CO, there were next to none. This is a lovely quick hike if you just want to get outside and move for a bit, but isn't particularly photogenic if that's what you're looking for. However, in winter it's spectacular for snowshoeing. We came on a Saturday in April and didn't see another soul til we got to the car. It's more strenuous on snowshoes, so that makes it a little more entertaining. The trees are beautiful in winter and you can't beat walking on a frozen lake.

Great morning hike! Took me 2 hours with a 15 min stop at peak.

This hike packs a lot in 4 miles, forest, meadow, great views throughout and three beautiful alpine lakes. Of course this also make it very popular. While there is not a lot of elevation gain it is over a fairly short distance so the trail is steep and rocky in a few spots. The last push to the top lake is short and up. Keep in mind you will be above tree line most of the hike so be prepared for whatever weather. This is a great hike for those who want a lot of beauty without a lot of mileage.

Wildflowers, snow pack, Alpine lakes! Awesome hike! It is a very busy trail that at times is hard to pass other hikers so come with patience. The road to the upper lot is very rough. AWD for sure with good clearance, but there was a Mercury Milan in the upper lot so maybe a regular car could make it carefully. Bring bug spray and sunscreen!

Certainly challenging, but nothing to lose sleep over. Expect to wait in line if you’re hoping to get decent pictures at the top.

The view is amazing! Someone was also kayaking in the Silver Dollar Lake.

"Stairmaster Sanitas" is a great place to get a very real workout in. We are in decent shape and climbed up Sanitas and went back around the valley loop trail within 2.5 hours. I would categorize this as "moderate to hard" given a few of the rocks you have to scramble over and how steep it is. While you can carry a child on a backpack up an down, it's not the greatest one to choose for that since you might have to shuffle a bit over rocks, etc.

This is definitely a “hard” trail, bust super proud when I finished! Practically all up hill on the way there but that means down hill on the way back! The views at the top are beautiful! I would recommend starting it sooner rather than later so the traffic is low and the sun isn’t too high!

Beautiful hike, great views and perfect weather!

Got there at 8am (Saturday), parked at bottom lot after questioning driving up the dirt road (on my way out there was a crew filling in the holes with dirt to make it more accessible). Only ran into a handful of hikers on my way up (I also try to hike at a faster pace). Could have made it up faster, but the views were too beautiful and I kept stopping to take pictures. On my way down is when I really started to run into hikers with their dogs. Also saw families with young kids and a trail runner. Round-trip took me 3 hours, but I didn't stop and have lunch at the top - only took in the views for a bit, took pictures and then headed back down. The higher you get the trail narrows in a few areas, but wasn't bad - still clearly marked.

If you park at the bottom lot it is a bit more challenging, but I enjoyed the challenge (for me it wasn't too bad). By the time I left both the top lot and bottom lot was full. I was the 2nd person in the bottom lot when I arrived. Within 15min it started to fill up. Agree with previous comments - stop in Georgetown to use a bathroom before you get to the trail - there are no bathrooms or trash cans. Also saw the issue with left dog poop. It was chilly when I started, but by the time I made it to the actual trail head I was fine and the day continued to warm up!

We enjoyed this hike! It was definitely a high incline and rocky but it was worth it. It was a bit harder then expected the the views are beautiful and the arch is pretty neat. Bring lots of water, take stops and enjoy the outdoors! There are trees on a lot of the hike which gives some much needed shade every now and then.

Tough ascent in the beginning but worth it. First hike only see from a view. Once out of the tree then nice view, stream crossing, snow crossing.

Silver dollar is nice but if you went this far then go to Murray. Some other guys made it to silver dollar and turned around (didn't think Murray lake would be better)

On the way to Murray, mostly uphill but here is where all the flowers are!! Making it up, it would have been great to be able to explore but we had rain concerns (caught in rain, hail on the way back).

Did this hike with wife and 2 and 5 year old with child carriers for both. 5 yr hiked once we got above tree line on way up. On my way down she was carried , as we were trying to get out of the rain.
