This was an absolutely amazing hike! I only gave it 4 stars instead of 5 for the following reasons:
1. The hike is listed as easy which it definitely was not, I would say it is more moderate and that is due to the trail being super rocky, picture a river that dried up, that’s what the trail was. But if u can handle that than it is totally worth going, the views r just spectacular all around you! I highly recommend continuing past the lake to where the snow is, the views only get better and it was not hard to hike up there. 2. We got a lil lost on the way back because the trail is not clearly marked, good thing we had the map from this app and a friendly person to point us in the right direction.

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.

Nice trail with a variety of terrain. This trail may be considered hard for those who do not hike frequently... some narrow, rocky areas with over 1000 ft of elevation change. The river was a nice spot to stop for a rest half way through the hike.

A nice workout with a strong hill qt the end. - beautiful - the river was great for my dog too :)

Great short hike to a beautiful view. Would highly recommend bringing visitors here to show, great views and easy enough up and down while truly being in the mountains. Definitely great for the dogs as well.

I liked that this trail had variety of sceneries. Many shaded area as well as some meadows and rocky terrains. Great for dogs since there is a creek running by, and the lakes to get to. Wild flowers are beautiful in August. I saw a coyote (I think) and moose!

This hike offered a quick escape from Denver heat today, but not much escape from crowds. We enjoyed the trail, but it was very crowded and of course, there was a lot of dog poop along the trail and two dogs off leash, despite someone asking the owner to leash them. I think this hike would be much better during the week; it was just too busy on a weekend.

"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.

What a gem so close to Denver and I-70! We hiked on a Sunday morning in August. I hadn’t expected all those wildflowers in August—so lovely! This was a short hike we planned for the morning-we had to travel on to Salida that same day, so the 3 of us allowed just enough time to hike at our own pace, touch the glacier, enjoy the views, and get back to the car within 3 hours. I am tempted to rate this as 5 stars except for: toward the top, so many hikers have made branching trails that we weren’t sure which path to take to reach the lake (a helpful hiker passing us said: don’t worry, they all lead to the lake); parking was really crowded with few options; and the main parking lot was really rocky and our “standard rental” car bottomed out and scratched the undercarriage (thankfully not noted by the rental people). The views from the toe of the glacier are just stunning, so we didn’t try to go higher up the rocky scree slope—that looked like it would take more time than we had.

Scenic and forested. The last 3/4 of the hike got hard and had me wondering if I was ever going to make it, but it was worth the effort to get to beautiful mountain lakes.

Most of the hike in the trees. Better view on the hike than panoramic view (which you are can drive to).

If you are staying at the campground (which we were) the trail is worth the hike. Not sure I would make the drive just for this hike with so many other options in the area.

Perfect for a quick, easy, dog-friendly day hike. There were a lot of great areas to pause and soak in the view or just hang out for a bit.

This trail gets a bad wrap here! it was actually beautiful and the signage was just fine. I counted no fewer than 5 signs directing me along the trail. and the map IS accurate. just follow it while you are walking (pull out your phone when you get to a fork in the path) and if you take a wrong turn you can easily see it on the map on AllTrails.

Awesome ash trail! Bring $5 for parking

Wonderful little hike. I went with my 20 y.o. daughter and our 2 dogs. It took us about 1. Hour 40 minutes to do the loop. The old dog did fine, we had to give them water 1/2 way through. Loved the trees, flowers and a couple of pretty viewpoints.
Moderate family traffic on a Thursday.

This is an easy but beautiful hike! We love taking our dog on this one!

nice 2 hour hike, trails are not marked very well in certain areas.

We hiked this on the morning of 8/9/18, leaving the smaller parking lot at 8:45am. The trail to the lake is almost entirely rock; I’m guessing this was once a river bed, at least during the snow melt season in eons past. The lake, mountainside behind it, and the snowfield are stunning. We set off higher, and quickly lost the trail. There is a waterfall just below the glacier, and we ended up following some others up across the water below that - as in, through the water. This meant we were completely off the trail on the other side, but we stuck to other descriptions of staying to the right side of the glacier as we ascended. This was really tricky. We were just feet from the edge of the glacier, and the terrain is a mixture of scree and a variety of sizes of rock. Really slow going, lots of slipping on the scree. After about a half hour of this, we observed two people ahead of us walk across the snow (which eventually narrows to nothing as you proceed) and climb up the opposite side to a trail up there. We did likewise, and finally found ourselves on a real trail. Furthermore, at that height, we could see an actual trail on the side we’d been on, which wasn’t visible to us when we were lower. We continued on to see James Peak. It became obvious that unless we continued straight for an uncertain distance that all we would see was the top of the two mountains. At 2.20 miles from the start, we turned around. The trail we were then on was going to take us to the left side of the glacier, which then ends at the glacier, so we knew we had to cross back over and get on the real trail there. We skirted along the top of the snowfield, lots of scree there and steep, although not any long distance down. We got onto the actual trail, and picked our way down as there is still plenty of scree there too. We got back to the lake area, and found the official trail which, surprise, does not walk you directly through the waterfall stream. The rest was easy enough.

This is lengthy to let others know: 1) that the trail just up past the lake isn’t necessarily easy to find; 2) the trail farther up from the lake can be truly difficult to find (we saw several people ascending the way we’d gone); 3) there is no actual end point on this trail nor any “wow” view up higher; 4) so. much. shifting. scree, so be prepared for that.

We got to our car at noon, and the large parking lot appeared full as we drove past it. There were tons of people. It’s very popular.

AllTrails rates this as Easy. However, we have a book of hikes that rates it as Moderate. Our hike was a challenge, certainly not Easy.

Went early August, late morning. Plenty of parking in two lots - only saw a few people on the trail. Trails are well marked. I took West Ridge Trail to Bear Creek Trail to Bear Creek Cutoff. Was a lovely mix of forest and meadow - lots of beautiful flowers! Saw a stag, two does, and three fawns, as well as lots of birds and smaller critters. West Ridge Trail starts fairly steep, but evens out after half a mile or so. Bear Creek is shared with bikers, but wide enough it's not a problem. You'll hear air and road traffic, especially on the last portion of West Ridge, as it run parallel with Meyers Gulch Road. Had a lovely hike!

I loved the views this trail had to offer with the lake and surrounding mountains. I will say though that it was probably my least favorite trail to hike that I’ve done so far, and I’ve done many trails including 14ers. The reason I didn’t like this one was because of the gravel when you go to hike to the top of the glacier. There is way too much sliding around and stressing out trying to figure out the best place to put your feet without falling. I was not a huge fan of that. Other than that, it was really pretty, and if you hike to one of the trails to the right of the glacier, there were a ton of wildflowers and even more pretty views. I’m glad I did it, but I probably wouldn’t care to go back because of the rocks and sketchy trail to the top.

I started up the Sanitas Valley Loop first. Beautiful views of urban Boulder and a smattering of homes in the hills. The moderate valley trail gives way to some steep inclines as it connects with the East Ridge trail. I was visiting from Atlanta so I had to catch my breath and steady my footing as the trail ascended. Had to get used to the change in altitude. Plan to take your time navigating the rocky, sometimes not well marked East Ridge trail if your new to it and out there alone. I got out early in the am and had a few hikers help me find the trail but I can see that this trail gets very well populated after mid morning. At the top of Ridge Trail I met some nice folks who directed me to Lion’s Lair trail just beyond the summit for a good trail run. This trail was pretty smooth and the decline makes for a steady tempo run. Don’t get too comfortable because the switchbacks will keep you on your game. Overall a fun trail to test your trail speed. The locals pointed directed me on how to go from the Lion’s Lair trail to a narrow barely there trail that runs parallel to Sunshine Canyon Dr. This trail led to me the Centennial Trailhead parking lot. Overall awesome experience for a trail runner who wants to mix it up with a hike and run.

Gorgeous trail; good variety of strong incline, walking through forest, and climbing over some cool rock runs.

Went up there with friends and had an absolutely amazing time. The lake and glacier together looked beautiful. We hiked all the way up the glacier and to where it ended. From there we went back and climbed the row of mountains going back down on your right side. At the top there were many stunning views, where we took many pictures. We went down a small trail on the right side of the of the mountain going back to the lake. Everything was amazing and I would highly recommend going there. However, going up the glacier can be very slick. I would bring spikes to put on your hiking shoes! Makes going up it a whole lot easier.

Traveled with a 11 month old in a pack! Summit was breathtaking. The waterfalls are simple...not sure we found the real falls! There is a ‘creek’ area that was perfect for the little one to toddle around and throw rocks. I’d definitely recommend this trail.

Cool hike and views from the upper lake. Many, many people due to the parking lot being so big. I would rate the TH to the two lakes has a moderate hike and if you choose to go up that last .5 mile is hard. There are two trails up, the one in view from standing between the lakes is a scramble up and then down 150 ft to the lake. The trail to the east is steep too but drops you at the lake shore.

overall, nice hike with tons of people.

Decent 4 mile hike. Trail runners and bicyclists were frequently wizzing by, so just something to be mindful of especially if you bring your dog. Mostly shaded but there are a couple places at top to stop and catch a scenic view.

this incline is no joke! my poor pups paws were shredded after hiking these rocks. I ended up having to carry her 2 miles to the end. It was scenic but not as great as everyone makes it out to be.

Absolutely spectacular sights and a pretty short hike.

Good hike up, had a lot of fun looking at the glacier and walking on it. My group and I went cliff jumping and had a blast!!
