I did this hike 2 months ago. Trail is well kept. Pet friendly and just gorgeous spot to visit.

Great hike, not too hard but a decent workout. Some snow and ice at the top once near Snow Lake right now, if you have crampons on poles it’s not a big deal. The scenery was great, temperature wasn’t too cold, and not overly busy, worth the time.

Did this hike today and it was very very nice!!! A little muddy, but that’s ok. Very pretty peaceful hike only saw a couple others on the trail. It’s worth it to hike the extra mile to the second lake. It was fairly easy for the most part. A couple spots had your heart pumpin, but other than that it was very mild. The sounds of the water were so calming and it was very well maintained!! Had a great time!!!’

We did this hike on Mothers Day. We took the old trail up & new trail down..wear proper shoes for the down hill. Amazing accomplishment....hardest
one for me so far

I did this hike awhile back It can get crowded but enjoyed it all the same!

Wow!! That will be the reaction of 99.99% of people who do this hike, the other .01% are most likely crazy people. The magical, towering mountains around this mountain lake are simply breathtaking. It was a cold day with ice and a little snow in the higher elevations of the trail. The lake isn’t frozen over yet and the water still shows the bright blue color it’s known for. We clicked it at 8 miles round trip. Took us about 3 hrs up and 2 hrs back down. There is a few spots with fallen trees that you will need to go over or under. But overall the trail is very well maintained and easy to navigate.

Great as long as you go early

Insanely crowded. I felt like I was in a single file line going up.

the scenery is gorgeous, the air smells like christmas candles as you climb. First 3/4 of the trail are easy slow climb, after that it turns into more intense switchbacks. Very snowy and slippery at the top, so wear appropriate footwear. If you have removable krampons or hiking poles I would suggest those for the top portion as I saw lots of people fall and almost fell myself a number of times. I even saw a lady with a sprained ankle being carried down by her husband. Bring lots of layers so that you can take off as you ascend and then put back on as you descend. This time of year when we got to the top at 2:10 the sun was already set on the lake so get an early start, aim to be at the top for noon. Amazing view, so worth it!

Winter wonderland! Don’t forget your spikes for the last half of the trail.

Definitely a workout! Did this hike on Monday (11/13) and it was relatively busy at the top from it being a holiday. My phone recorded round trip about 12 miles, but I’m not sure how accurate this is. The last 0.5 miles are a grind but the view from the top is worth it. Watch for ice patches, poles are a good idea. When we hiked a group of hockey players were taking up a fire hydrant, look for it at the top!!

Really beautiful hike around this time of the year, this hike offers some of the best views Washington trails has to offer. The lake is starting to freeze up and theres lots of snow and black ice once you start getting to higher elevations so be cautious! I would say this trail falls more on the moderate side than hard, it took us 3 hours to get to the top and 2 hours going back down. Would recommend this hike for everyone!

The trail itself is great, but it's heavily trafficked

Beautiful, well maintained trail alongside a river. Slightly muddy but nothing too bad. The waterfall is beautiful and you can get pretty close.

great hike!!! lots of stairs!!! went early beat the crowds!!!

Winter wonderland! Over a foot of snow everywhere! Make sure you bring micro-spikes and hiking poles. Some spots get very slippery. The most beautiful wonder hike I have done so far. (Oh and wear waterproof shoes)

The only reason I am taking a star off is the lack of signs this trail has. Towards the end my friend and I took a major detour because there were fallen trees and the trail was hidden with snow. We found the lake though! So worth the hike we did it round trip in 4 hours and a half. Very icy towards the end so be careful.

I got engaged on Mount Si! Great day to go for a hike. Very clear and the trail was well maintained. There is a small spot where a tree has fallen over the trail and people have made a trail through it, but coming back down it’s hard to tell where it is. All over perfect day.

The trail is nice. It’s a good scenic trail with lots of cool places to stop and take pictures. The only bad thing is it’s a popular trail. Once you get to the top, you’ll be fighting for places to stop and take a break or pictures. We went on a Saturday morning and we were at the top with about 50 other people who had the same idea as we did today. The parking lot fills fast and people started parking on the street before the parking lot. So, we’ll definitely go back on a Wednesday morning or something so it won’t be so crowded.

Very pretty, easy hike. It's great for a fall/winter hike when the skies aren't as clear. Can't believe how many big and small falls there are.

Really nice hike with beautiful view points!

The trail was beautiful and the creeks were flowing fast. Lots to see! The lakes were peaceful and surrounded by snow dusted trees. The snow was just a dusting but the trail was very wet up top and some deep mud in places so watch your step! I would say this is an easy-moderate hike. This would be a good hike for families as there are flat spots in-between the switchbacks. The trail was closer to 6 miles. Great late fall hike!

**You will be on the old trail because the new one is under construction but it is well kept and meets right back up with the mapped trail.

Great Hike.

Great hike for all age groups. If you’re not a beginner, I’d recommend trail running as well. Breathtaking views from the cliff. You can continue further if you wish as the trail continues further. Took us 3 hours from car to car including breaks. Would highly recommend for sunrise.

My friend and I, who I'd classify as novice hikers, were able to complete this hike in 7 hours. It took us 4.5 hours up and 2.5 hours down.

We went on Nov. 2nd the conditions were muddy at most. No ice on the trail that we experienced.

There are some seriously beautiful viewpoints on the way up and was well worth it at the end. Unfortunately it was cloudy and rainy so we hope to go back again in the summer to see it all again.

We persevered but I wouldn't recommend this to someone who is totally inexperienced. It was very hard for us. However, a great hike for any seasoned hiker.

In addition, we both recorded approximately 10 miles, not the the listed 7.7 miles.

Unfortunately there was too much water to cross one of the waterfalls that had developed due to the rain lately. We were one of four groups that doubled back. Seems like it would be beautiful based on the first 30 minutes though!

This is one of the most beautiful places I’ve seen in my life! The trail is tough but not as hard as some other hikes I’ve done. The views at the top are absolutely worth it, take a day trip and go here. You won’t be disappointed! Also, lots of Chipmunks!

Steep for kids, but amazing views and great lookout at the top. Mountain stream just over halfway up.
