Beautiful scenery the entire walk and quite spectacular at the top. Considering the low mileage the solitude at the top was surprising.

This hike was stunning. It was a pretty quick one, it took us two hours to get to the top. The trail itself was easy and well maintained, the hard rating is due to the near constant elevation gain.

The hardest part is the last stretch before you top out to reach the lake, so be prepared for that. The switchbacks are very steep and in the sun. There were a LOT of gnats around the lake but the views were beautiful.

We started at 8am and the trail was pretty unpopulated. We ran into a LOT of people making their way up as we came down, including people blasting music from their phones (please do not blast music on trails).

Challenging, but totally worth it. It was a steady uphill with some switchbacks to start, followed by some serious rock navigation. The toughest part was the switchbacks up the mountainside around mile 2. Poles would be handy. the lake was gorgeous and peaceful.

Wonderful hike but it was tough for us two 50-something flatlanders with only one day acclimating. Loved lake.

Hard but really rewarding with beautiful vast views and the lake at as a nice reward at the end. Difficult and moderate parts with beautiful waterfalls and wildflowers. Looking forward to doing it again. A fun hike with friends.

We hiked in late July on a Saturday and the trail head parking area was full. We parked on the road with a large number of hikers. The trail rating is correct and the trail is well maintained. There were lots of wildflowers and a number of scenic views. The area near the lake and the lake itself were great.

Hard hike but just as scenic the entire way up as at the top. We got lost at the top, so stay left and cross the creek. No snow on the trail as of 6/16.

Awesome trail, no snow at all. Took us 3 hours with a short lunch break at the lake.

As of 6/1/18 the top is still snowpacked and the trail easily lost. Can’t wait for a few more weeks to try it again.

Beautiful trail! As of 5/26/18, the top portion of the switchbacks are still snowpacked and extremely difficult to traverse, and the lake is frozen. If you are hiking to see the lake, I would recommend waiting a few more weeks. I am excited to try the hike again later in the summer.

Stunning views!

Awesome trail! Beautiful views! Lake was a beautiful turquoise color. Shortly after reaching the lake the sun went behind the clouds and a weather system came in so we had some snow! Continuous assent made it challenging and going down wasn't any easier. Would definitely go again though.

Went October 5th from 11-4pm. Took me and my girlfriend visiting from FL about 5 hours and was very difficult for us. The switchbacks towards the end were very muddy and had a lot of slush making that last bit very dangerous and nerve wrecking! Saw others with poles going up with ease. The view was absolutely breathtaking and so worth all the struggle ✌

Road to parking lot a bit bumpy. First to the lot for the day. 34 degrees to start, but was down to short shirt sleeves in 1/4 mile. Aspens are starting to look beautiful in several areas. Hike was hard, but very much worth it.

Aspens had just begun to turn which made an incredible hike even more so. It was strenuous but well worth it.

Absolutely beautiful start to finish. Sept 1 , parts of the aspen groves have started to change to gold. There is a side trail to see castle creek acting more like a rushing waterfall just past the aspens. Once you get through the switchbacks, you're solid! A lot of different trails to get across the creek to the lake, they all seemed to work fine. Hike around the lake to the boulder field for best views and a great lunch spot. 4.5 hours round trip with a lunch break !

The first .7 miles or so is easy and covered by Aspen trees. After that, it starts to get rough. While it is a steady climb, if you are acclimated here in will be fine. My 8 year old dog and I (24) did it in four hours. There is a pretty big waterfall just off the trail after you come to a little clearing (stay right here). After a while, you will come to a spot where you can go left to the river or right...go right! It is a bit of a rock scramble from there. Then you follow the trail until you hit the super steep 1/4 of a mile climb up the switchbacks. From there it is another ten minutes or so, when you get to the stream...stay left for an easy hop to the other side. If you are hiking with your pup...bring water! The stream isn't until the very end but there is a spot where you get closer to the water and can take the trail down on the left to let them get some water for them. So worth it!! Tons of wildflowers along the way and the trail is easy to follow. No snow left and the lake is completely thawed.

Amazing beauty the whole time! The end is absolutely spectacular. The lake is so cool. Would not recommend this trail to beginners or those who are not in good physical shape: the trail is constantly uphill and extremely steep towards the end.

Extremely difficult hike, but so worth it for the view.

A good hike for the area. Completed it this morning. There was still a little bit of snow but nothing that you can't easily avoid. There was also one small section of mud, but again easy to maneuver. Eventually, right before the lake, you come to a "T" in the trail and a stream. There are stepping rocks in the stream but most of them were under water, not a problem for high top waterproof hiking shoes..but, if you take the trail to the left a few feet there's a big boulder and it was very easy to step up on the boulder and over the stream.

gorgeous, pretty strenuous hike - went in early june and there was still a TON of snow. spent the last 1.5 miles crossing the snow. would bring different footwear next time. would love to see the lake when its not frozen!

A pleasant hike, yes strenuous, but a nice gain in elevation at a quick rate, The payoff is well worth the trek. Having been on this trail twice I have experienced different conditions: the first time up, the wether was cool and drizzly and the only concern was slippery, muddy surfaces on some hairy-steep switchbacks. However, the second time around, just this last June, included a great deal of snow at expecially critical points in the trail-- namely, the boulder field and at the top of the switchbacks as you reach the plateau where the lake sits. Just enough of the unexpected that added a welcome challenge to the hike. The lake was still frozen but the beer and the jerky at the top, and a little snooze in the warm sun before heading back down sealed the deal. I highly recommend this trail.

Fun hike and lots of great views along the way. Lake was about half frozen over and expect snow the last mile or so. Trail is difficult to follow at the top (due to the snow), but if you follow the river (don't cross it) - you shouldn't have an issue finding the lake.

Amazing hike. Aspen groves in the beginning are beautiful. Once you get a little higher there is a section of aspen grove that has been strewn across the trail from a winter avalanche. Nothing you cant walk over or around though. A few snow patches on the way up. The last 1/4 mile after the steep switch backs is completely snow covered and you will likely lose the trail. Follow the footprints and you should be fine. If you lose the trail just walk up toward the cirque and follow the creek. Lake is frozen over but still amazing. Enjoy and don't be afraid of the snow.

What a hike! Probably saw about a dozen people over the 6 hours we were there. Gets steep at times, but the views are well worth it, and the lake at the end is pristine and beautiful. Had great weather, especially for October.
