Did this trail on 12/8. Perfect hiking day. Some powdery snow on the trail, but no need for spikes. Great trail close to town.

Completed hike on 12/8. Very rewarding view of Longs and the Mummys. Add at least a 1/4 mile from parking lot to the trail head. Began at 10:30 and was on the first summit by 1. Snow pack almost the entire way- much deeper at RMNP/National Forest boundary marker. Crampons definitely recommended. Can easily summit both "sisters" within an hour (plus lunch). We were lucky to have minimal wind at the summit, but it was cold- roughly 15 degrees and colder with wind chill. All around amazing, not too difficult of a hike even with the snow. Plan to be back in the parking lot by 4:30 (sunset).

My father in law and I hiked this trail this afternoon (early-December) and it was a nice 4 mille in-and-out trail with beautiful views of the reservoir at various parts of the hike as well as a gorgeous view at the top. I would rate it as moderate mostly because of the steepness, but it was very doable. The steep parts were made easy by rock steps and no part of the trail was terribly treacherous. About 2/3 of the trail was covered in snow (beginning and end) but it wasn't icy. It took us a little under 2 hours to complete.

Great hike and view from the top spectacular!

Little cold and windy today. The trail was pretty well packed with occasional snow drifts but nothing crazy. Able to make it to both peaks. I was fine with spikes and gaiters. The road is closed maybe half mile from the actual trailhead but if you park in the little lot by the gate I don't think it adds more than a mile round trip.

It’s so beautiful! We went in August later in the afternoon and it wasn’t terrible crowded. We had the final 2 lakes all to ourselves. The stairs heading up to the waterfall were the worst part. Beautiful hike!

Significantly longer than the official 7.5 miles due to the winter road closure at the parking lot just off Hwy 7. You’ll walk up a snow covered road a long way before getting to the trailhead and starting the actual hike. Micro spikes got the job done, though there were some deep spots above tree line, approaching the summit. Amazing views of EP, parts of RMNP and out to the plains.

Gorgeous hike in late September. Colors abound, blue sky, no wind. Stopped at the Loch for a snack break and then onward and upward. Icy near the falls right before sky pond...and the falls were quite icy. Did not attempt to climb on up. Views from below the falls back towards Loch just outstanding. Decent days hike but if you take your time (especially if you are a flat lander in your late 50’s...) it can be done. Favorite hike yet in RMNP. May try going up during warmer weather next time.

I made it to Sky Pond on 11/12 after about 6 inches of snow the night before. The trail all the way up to the Loch was well traveled and I was able to do it with good winter boots only, no traction devices needed although as the fresh snow goes away and turns into ice I would highly recommend Micro spikes. After the Loch snowshoes were essential and the climb up to Lake of Glass should only be attempted with crampons/ice axe it is almost entirely ice and rock at this point. Put your snowshoes back on for the last half mile to Sky Pond and enjoy, definitely one of the best destinations in the park.

Made it to Lake of Glass last week after a scale up glacier and snow. There wasn't really a trail so went off the cuff with my boy, snow was deep af. Was a lil past 3:30pm so didn't want to head full way to Sky Pond just to be stuck in the dark trying to make way back down cliff side. Such a sick ass trail and experience though.

Such a beautiful hike! I wore microspikes the entire trip up to the waterfall which is around 9 miles round trip. I would definitely recommend wearing snowshoes though. I sunk up to my thighs in certain places by the Loch lake. I saw quite a few people up on the trail today they said that people were using icepicks to get up to sky pond.

Was an amazing trail with quite a few spectacular sights. Happened to be snow up there in October and made it difficult without proper gear. Crampons needed during winter months for sure. We didn’t make it up the waterfall scramble with just hiking shoes. Was way to slick. But still recommend this trail. Turning around near waterfall ended up being about 13 miles round trip with one wrong turn.

A very exciting hike, at least during wintertime. Looking forward to coming back during the summer when the lakes aren’t completely iced over. Hiked it with a friend about 3 weeks back and definitely recommend micro spikes. I couldn’t really imagine doing it now without them. Most of the trail is pretty manageable with some decent inclines but, as most people have said, the trickiest section is the scramble right next to the waterfall before glass lake. It was very icy and very slick, I would not do this one without micro spikes. The views once you get to the top are very nice, and make for a nice experience. We arrived at the trailhead at around 6:50 AM to avoid crowds. On the way up, we bumped into a few people, but on the way back down there was a steady flow of hikers. I would recommend doing this hike nice and early to avoid the most crowds as possible.

Steady climb on this, not too taxing for a local. Had a friend in from MN who did all right. Trail is a boot pack, snow the whole way up, 0"-10" and slushy on the way down. Would have been prudent to have snowshoes past the NP/SF boundary marker, but we summited in approach shoes and got a little wet. Good views on top with high winds and clouds sailing past. 4.5 hours round trip and only saw 7 other people out today.

I just want to clarify some of the statements on this thread. A lot of people seem to refer to "climbing a waterfall". There is no climbing of a waterfall on this hike. There is however, scrambling on slick ice "on the trail" adjacent to the Timberline falls. As mentioned by many reviewers, this scrambling is no joke and I wouldn't recommend it without microspikes. However, you will not be climbing a waterfall on this trail, or at least you don't have to. Such statements on the reviews made some of my friends very nervous about doing this hike. I thought I'll clarify it for others.

Absolutely gorgeous trail... scenic the entire hike! We rented micro spikes from an outdoor shop in Estes.. wouldn’t recommend the last half of this hike without them. The waterfall is iced over and caused difficulty getting to Glass Lake but once you’re over that climb, the rest is easy. We had lunch in a Little Rock shelter by Sky Pond that helped block the crazy wind. The trail is clean but there are a ton of people hiking it so there’s not much solitude. We did a hotel in Estes Park and drove into the National Park so we could be there bright and early... VERY cute town! Plus it was nice to take a hot shower and sleep in a nice bed after this hike in the cold windy weather!

Just what I was looking for! My second day in Colorado and this was a great challenge. Took 2 1/2 hours up, wish I had spikes on my running shoes at the top, but I made due. Windy at the top!! I also want to mention, I am not a hiker.

Wonderful hike! Worth the scramble up the the waterfall.

Great hike! Beautiful small waterfall to be seen after climbing the larger fall immediately before Sky Pond. Scaling this is not difficult. You pass several alpine lakes, which can have mosquitoes during the summer. Marmots at the pond can be aggressive in their pursuit of your pack and snacks.

4 stars on account of the parking situation.

Really fun hike. Hiked on 25th Oct and started around 9am. We didn't have crampons or microspikes and did find the snow and ice a little slippy in patches but still totally doable in hiking shoes. We found hiking poles useful. The view at the top is breathtaking. West peak is easier to get up than east, but my husband did both without too much trouble.

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.

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!

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.

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.

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.

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.

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