Definitely still doable, recommend having some sort of traction (Yaktrax were perfectly fine when we did it) and maybe trekking poles to keep from getting blown over by the winds above treeline.

Beautiful.

Well packed snow on trail only needed micro spikes. Some posthole on upper portion above tree line. Beautiful hike

11/2 - there was not much snow at the time of our hike. Patches of ice and snow, but nothing microspikes or yaktrexs can’t handle. The ridge to chasm lake was also clear of ice and snow. It was a bit windy once you hit treeline

Nice trek to Chasm Lake a little late in the year but very doable. Icy trails intermittently after leaving the tree line. Quite windy on the way up but calmed down on the return. Kahtoola Microspikes came in very handy on the ascent up to Chasm Lake as the path was a sheet of ice. It was safer to boulder and rock climb up the face avoiding the trail. It was worth the effort!

Hiked this trail 10/21/17. Would not suggest hiking to the lake itself in this time of year due to biting winds, deep snow, and very slippery ice. The trail is beautiful the whole way and the view of Long's Peak is stunning! However, the trail up the two ridges to the take (at about 4.2 miles) is very dangerous at this time of year due to lots of ice. I completed the scrambling with trail running shoes but would highly recommend microspikes. A fall off these boulders would result in serious injury.
I completed this hike in 5 hours-much longer than I thought it would as I am a fast hiker but the ice and snow forced me to slow my pace tremendously. My GPS watch clocked 9.1 miles. It was about 20 degrees the whole way up with serious winds-not a fun climate. Make sure to wear adequate wind protection as I got first degree frostbite on my fingers, even though I was wearing gloves. I would love to come back in the summer to have a more enjoyable hike. Due to bad weather and lots of ice, I unfortunately did not enjoy myself that much.
The views of Long's Peak are absolutely spectacular...I can't stress this enough!

Watch out for unexpected snow storms.

Hiked it yesterday..I would rate it hard because of elevation change. As a person who lives at sea level, I found this harder than Twin Sisters but worth the effort! Made it all the way and just missed being caught underneath an ice slide that gave way above the trail just before the lake.!

Chasm lake was beautiful! Sits just below Longs peak. 9 miles round trip. The hike was easy until you have to scramble some rocks at the end. About 2-3 false summits! Just gotta keep going until you see it! We did it while there was snow!!! A lot of people turned back but we pushed through and made it with another a couple.

Beautiful hike with an incredible change in ecosystems. We got there late as Trail Ridge Road was closed yesterday and we had to drive from the west side of the park. Started at 1pm and hiked up to the top but given the fog the visibility was poor. Not disappointed as the hike was beautiful in itself. Finished in a little over 4 hours. Would do this again if we come back to hike Longs.
