Very nice forested area following the Big Thompson River or Fern Creek the majority of the way to the lake. It's very easy and flat up until The Pool, at which point it begins getting steep. About halfway to Fern Falls, ice becomes more and more prominent on the trail. Microspikes are recommended to get to the Falls and beyond. From the falls to Fern Lake is primarily iced over on the trail. Gorgeous views once you reach the lake, which isn't iced over yet.

I made it there right around sunset, considering going to Odessa, but some hikers said it was completely frozen over and steep to get there, so I ended my hike at Fern Lake for this trip.

Hiked this today, I'd definitely recommend microspikes. I ran into a lot of people having very bad times on the trail with just shoes. Personally, I turned around right after the waterfall - lots of steepness/ice and I was a bit anxious since snow and ice earlier on the trail had started melting. I did run into a few people who either got to Lake of Glass or all the way to Sky Pond, so it's definitely doable if you know what you're doing.

Excellent hike to Chasm Lake on 10/20. Started at 7am. Total moving time was 4.5 hours roundtrip, with an additional hour spent at the lake as we lucked out with zero wind and warm sunshine. The lake was about half frozen. Excellent views of Longs the entire way. Trail was majority covered in snow, but packed. Microspikes were worn the whole way. No issues crossing the boulder field. A little slushy on the return hike. Some short icy patches climbing up to the lake. Just go slow and watch your footing. Very happy to have completed this hike after attempting 1.5 years ago and encountering 50mph winds at the trailhead.

Hiked this trail with my fiancé on 10/21 around 10 AM. Lots of parking spaces available and hardly anyone on the trail- We were able to get to the top in 3 hours with plenty of breaks thanks to our trekking poles and crampons. More than half the trail is covered in snow and ice. The summit was absolutely beautiful. There is a spot for you to sit and take in the view. You get a great view of Longs Peak and Estes Park. We don’t recommend going to the East twin peak as there is no trail to the top and falling rocks make it super dangerous. It took us 1.5 hours to get down. Best hike in Estes Park!

We turned around before we made it to the falls, so I’m taking it in faith it would have been worth it. We were about 3 miles in, about a mile past the Pool, when the trail turned to ice. Without traction or poles it wasn’t worth it. I’d call it fairly easy to the Pool but definitely moderate once you get past there.

Hiked this in the afternoon on the 18th. First time to the park and the trail. Wonderful day. Due to some traffic, I made it to peak with trail running shoes...just a couple slick spots.

A great path walk/hike for families or people coming from a low altitude. We easily took our BOB double stroller because the path is paved and wide enough not to bother people with it. We had a great time watching baby beavers in the lake and throwing snowballs while walking. A great warm up to the bigger hikes in RMNP. Lots of parking and not too busy.

Arrived at 8am to a mostly empty parking lot on a chilly morning. Started the traverse around the lake with a very close encounter with a pair of moose! My 4 year old really enjoyed the lily ridge trail with endless climbing opportunities right off the main path....we spent almost 2 hours going off trail and had a blast. Enjoyed Lily Lake more than Bear Lake or Sprague Lake because of the variety offered by the lily ridge trail. Highly recommended if you have young kids.

There was some snow but nothing hiking boots couldn’t handle. The open meadow section was nice with the running creek and we saw some deer. Once you get in the wooded part it gets really pretty and a little more climbing. Parking was packed around noonish but we waited for 15 minutes and someone left to give us a spot. I imagine this hike is awesome in early fall or spring with the leaves but it was a great way to spend the day.

Great hike! 85% of the trail was ice covered. Make sure you pack some crampons!

Hiked this today. Most of the trail is covered in snow and ice— definitely need microspikes, especially for the last half mile. Past Lake of Glass the trail is hard to find. Snow is deep and the path beat in through the snow is not the actual trail and can be hard to follow. Weather was absolutely perfect!

My wife and I made it all the way up with only our hiking boots. We both agree that going up with crampons would have been better. We had one slip/fall on an icy decline. Plus going up the water fall just below Lake of Glass was a little dicey, but a decent amount of people made it up and back down. We enjoyed trotting our snow pants up and put them on for the decent so we could “sled” down some of the steeper areas. Others were jealous. Overall we loved our trip. Walked over a frozen lake and Sky pond was just beautiful to celebrate our 5th anniversary.

Easy trail to a really pretty waterfall. Hiked it on a Thursday (10/18) and only saw a handful of other people. Took about 3 1/2 hours but we stopped and took pictures several times and hiked down and ate lunch on the rocks right beside the waterfall. If you want to take a fairly easy walk, this is a good one. Not much elevation gain and trail was very easy to follow.

This is a nice, wide trail with not much elevation gain that I hiked on Thursday. It was really icy on the trail so wear good hiking boots and I’d recommend trekking poles too. I didn’t have poles and slid around a lot!! Still a pretty hike to a big open meadow. Think if it hadn’t been for the ice, I’d enjoyed it a lot more.

I did this hike 2 years ago and it remains to be one of my favorites. The trail is covered in packed snow the entire way, so I would definitely recommend having micro spikes on hand. It can definitely be done without spikes, but it just might be a little slower/harder/more slippery. Once you get above tree line you might find yourself following footpaths that are definitely not the real trail, but it will get you up to the trail junction between Chasm Lake and Boulderfield one way or another. A breathtaking view of Longs is visible for most of the hike (above tree line) but it’s even more amazing to have it looming above you once you’re finally at the lake.

Really beautiful and super fun, but definitely needed our crampons. Poles would have been helpful on occasion as well. I wouldn’t advise doing this one so late in the season unless you have the right gear for snow and ice.

We absolutely loved this hike yesterday. I went with my 2 adult children. A lot of it was in open meadow, which would have been brutally hot in summer, but was pleasant now with temps in the 50’s. After the meadow, there is considerable hiking in the woods beside a stream which is lovely. When you get to the base of the falls, which arguably aren’t too big, you may think you are done. But we watched a group of three cross the stream and head up on the left side. Good luck finding the trail, as it appears nonexistent at this point. It is fairly steep and made me slightly nervous, but I have a severe aversion to heights and steep drop offs. What I’m saying is....if I can do it, you can too! The view at the very top did require some scrambling up rock surfaces but was worth it. We were told by the group of 3 up there that you can even climb higher by crossing the stream again and hiking up to the tip top, but we simply could never find this, and I was relieved because it looked steep! I was with 2 adult children, and it gets difficult to keep up, but I am mostly determined! We arrived to this trailhead at 10 and took the last spot there. There are not many spots so plan ahead!

Not really a hike, but still worth the short walk around the lake for the amazing views. We got some great photos of three moose taking a stroll through the lake during our walk on June 27, 2018.

Great introductory trail to RMNP. Easy for all ages and abilities.

Full on winter conditions up there now. Micro-spikes or other traction control would be advisable. The trail is well packed snow/ice. I didn't go further than Sky Pond due to the deep snow.

Hiked Twin Sisters trail on Oct 19, 2018. left parking area at 7 am and had the trail to myself. Some areas were snow covered with packed snow and ice. Bring Yak tracks! Beautiful 360 views from the peak.

Amazing and challenging hike. Chasm lake with a little bit of snow on the ground was quite a sight to see. Once you break through the forest the views are breathtaking.

Beautiful trail!! Couldn’t make it up the waterfall (covered in ice) without crampons but the views were still gorgeous.

As Galen noted below, heavy snow drifts up above Lake of Glass. Difficult to distinguish any trail in the snow. Found myself somewhat unprepared for this level of snow. I felt this trail was overrated, but I bet the experience is better in the summer.

My journey began with a quick saunter through Lodgepole Pine trees, which were intertwined with Aspen’s still holding onto their brilliant orange and golden hues before I crossed Beaver Creek about 3/4 of a mile from the trailhead. Another 3/4 mile up the trail there are two large boulders, a great spot for a quick respite on the way up or backdown from the lake. From the boulders it is about another mile to the landslide. Once I had reached the landslide, I had two options: a) climb through the landslide and risk it shifting (very unlikely) b) climb a steep vertical pitch over the topside of landslide and descend an even steeper pitch on the opposite side.

Incredible view of multiple lakes and Mountain View’s, steep climb in the half mile

Beautiful. Even with deep snow, the entirety of the hike was wonderful. Moose, Steller’s Jay and lost of views. Scrambled up the frozen waterfall to Lake of Glass, but the trail disappeared into chest-deep snow. Loch Vale was lovely too. Truly, we loved it all.

It's a pretty trail that I'm sure is nicer during the summer months. More than half the trail is now iced over towards the higher elevation. Made for an interesting trip up and down. Once you arrive, its very nice view but I'm partial to others in RMNP like Sky Pond, Emerald, etc. PS: The actual hike is more like 4 miles each way if my Suunto is correct.
