Hiked on 4/17/2018. Left Long's Peak Ranger station at 9:15am and reached Chasm Lake at 12:00pm. Did the whole trail with micro-spikes only. Trail is well traveled and well packed. Micro spikes a must. Weather was perfect on the way up, clear and a little windy. On the way back around 1:30pm it got really windy and started snowing. I made a hustle to get back to the treeline as fast as possible. Made it back to the Ranger station at 2:15pm.

Love it. Amazing views!

Hiked on 4/16, the trail is well packed with snow, and not super icy. I would still recommend spikes and poles, but snowshoes are not needed. Above tree line, this trail can be brutally windy. Me and some other hikers in front of me were turned back by gale force winds that would knock you over and make it difficult to move forward. I would recommend checking the wind conditions for the trail, but even making it as far as I did the views of Longs Peak were seriously awesome.

Beautiful winter hike, gorgeous views of Longs Peak. Didn't need the snowshoes yesterday but was glad to have the microspikes. There are a couple areas of exposure just before the big snowfield traverse, probably better early with ice and microspikes than later with softer snow.

Hiked yesterday. Packed snow and ice along the trail, but was able to do it in just hiking boots. Trail is pretty poorly marked so you definitely have to pay attention. Some scrambling toward the end of the trail. Views at the top are GORGEOUS!

Hiked on April 14th. Great hike! Definitely need micro-spikes. Really, really beautiful. The drop from the trail to Chasm Lake is actually pretty steep, which in the snow we decided to do anyways and just took some small boulder climbing. AMAZING views. The final few turns in the trail after the privy had some icy spots with steep drop offs but with the micro-spikes it wasn’t bad at all, just take it slow if it’s icy. It’s just so freaking beautiful. Start early in the morning. It gets icier and windier in the afternoon.

Hiked on 4/9. There was 2-3ft of fresh snow above tree line which made it very difficult to find the trail. Snow shoes are a must with all of the snow.

Absolutely beautiful hike. Not too difficult and definitely worth it. Amazing views of Notchtop and Flattop. Beautiful day today (4/3) but pretty windy. Snowshoes are definitely a must. Might be able to get by with microspikes but prepare for postholing. Especially with the wind, the trail is somewhat difficult to follow. There were a few times I pulled up my AllTrails map to find where the trail was. It’s just not too obvious with all the snow, especially the closer you get to Mill Creek, Two Rivers Lake, and Helene. Planned on continuing down to Odessa but as said below, the gorge looked like a death trap.

It's certainly pretty, but this has to be one of the worst marked Trails I've ever seen. I got lost multiple times. I don't even know if I ever made it to the job. Very frustrating.

Fun hike with my son! Need spikes when coming down towards the top because it is slushy and snow packed in areas.

Trailhead parking is on the road. The trail gets hard to find a out .8 miles in. Nice overall hike, a few spots on the way up would have been nice to have micro spikes. By 10am the snow was starting to melt and it created some challenges coming down without solid footing.

(3/26) Good hike. Excellent views from the summit. The trail gets a bit lost near the top, but if you look for the carins you can find your way. Traction not necessary but could be helpful as some spots are slick. We made it up without too much trouble in hiking shoes/tennis shoes. Very do-able for the whole family (ages 10 and up). My Garmin clocked this at a bit over 4 miles out and back from trail head.

Hiked today 3/25. Started early in the morning and was the first one to the lake. Only need microspikes, snowshoes are a bit much, at least until the next snowfall. I started at 6:00am and it was a bit windy. Made it past the snowfield with no problem thanks to the previous tracks......but coming back was a different story. I stayed at the lake for about 2 hours and that was enough time for the sun to soften the track on the snowfield. As I was coming back across I slid about a quarter of the way down and had to dig into the side of the snowfield to make my way back up. Be careful once the snow begins to melt it can be a bit treacherous. I would go as early as possible if the weather is warm, to make sure the snow stays solid.

3-25-18 Little Gem outside the park. Suggest an early start as there isn’t much parking along the road, trailhead just before Lilly Lake TH.
Nice rolling climb, scramble last 200 ft or so. Bring traction, parts in shade still covered with snow, makes it a more enjoyable trek.

Hiked on 3/24/18. Started at 7am with mostly snowpacked trails along the way. Met up with a couple other guys at the Chasm/Boulderfield split, and hiked all the way to the lake. We hugged the upper incline and it was fresh 4 in of powder with a thick layer of ice underneath, highly recommend at least microspikes. The wind was mild and final destination was totally worth it!

Hiked 03/24/18- microspikes very helpful. Multiple social trails after treeline break so keep your eye out for the cairns but you have an epic marker: the diamond and keyhole of Longs Peak. Above treeline, very mild “posthole-ing” (less than 8 inches) but past the fork to Chasm or Boulderfield is a different story. Too off camber for snowshoes in my opinion and spikes worked but you had to be diligent. Considerable “posthole-ing” at times just before the 2nd privy and headed up to the lake (depending which route you took: Rocky scramble/icy or posthole land). We lucked out with little to moderate winds and lots of sunshine! ENJOY!

NEED microspikes to scramble too top but worth it for 360 mountain views. Also, Garmin pedometer clocked at 5.5 miles.

Spikes only needed on 3/17

Spikes are definitely needed, hiking sticks come in handy as well. Bundle/layer up for sure and enjoy the beauty that is Chasm lake, so worth the climb!!!

Microspikes were definitely helpful, but snowshoes are probably overkill now. We had no problem making it to the lake with just spikes. The snow was only not packed down right near the lake

Hiked 3/12/2018. Spikes were not needed, but would have been nice leading up to and during the scramble. The dog and I made it up fine.

You need traction from Bear Lake to Lake Helene. Trail is hard packed and slick for most of the way to the Flattop junction. After that I'd recommend snowshoes simply because if you step outside the narrow line of hard pack you are in for a surprise posthole. Winds and snow night of 3/8 scoured off many long stretches of visible signs of the trail past the banana bowl.

Grace Falls is absolutely massive this year. Did not venture down to Odessa. The gorge looked like a deathtrap.

Tried to do this hike a week ago. The snow was not packed at all unlike many of the other reviews. Our feet sunk in 3 feet with every step on the way up and it was incredibly tiring. Once we broke the treeline, the wind was so strong that the trail disappeared and my gps unfortunately glitched out. We brought microspikes and trekking poles, but I imagine snowshoes would've made it a lot easier. We had to turn around past treeline due to the aforementioned things, but I still enjoyed it and will be trying again soon.

Attempted on 1/27/2018.
I used my Microspikes and found it very doable. Made it all of the way to the base of the lake after pushing through 50+ mph winds. Only to find that that the snowfield had not yet been traversed. The guy in front of me had 2 ice axes and crampons and was not able to make it across. It was absolutely beautiful and will try again!

A bit hard to follow after you leave the main trail, but the views are amazing and I didn’t see a single other person the entire hike.

Chasm Lake is one of my all-time favorite hikes. The views
along the way, ... Peacock Lake, Chasm Falls, wildflowers,... just awesome! I did this hike in July 2016 - perfect hiking weather, and the snow had just melted past the boulder field. The boulder field is one of the most challenging / taxing parts of the hike; your thighs and legs get a workout an it slows your hiking pace down. The last part of the hike, you need to scramble up a steeper area and I needed to watch my footing and take my time. But the views of Chasm Lake over the ridge and of Longs Peak were just Amazing! The CO Hiking book and RMNP said this hike was 9.4mi. I know it is rated moderate here; CO Hiking rates it Moderate - Strenuous and I agree. I was glad I started this early morning. Had time to eat and take a break at Chasm Lake before hiking back. By the way, did any of you hikers try that "outhouse" that hangs over the ridge? Crazy!

Loved this trail! Steep at times for a challenge, but quick enough for a half day trip. Views at the top of short scramble were incredible. Off the beaten path and super quiet (not much parking at the trailhead, plan accordingly). Snowpack was melting so it made the trip out a little slippery, but doable in just boots.

Fantastic trail with incredible views all the way to the top. Covered in snow on 2/4, but was fine in boots, didn't even use spikes. My 10 year old daughter made it to the summit, so can you. Worth it.

Great views for such a short hike. A couple inches of snow made trail finding tricky at times but didn’t need spikes. Incredibly windy at the top.
