Amazing old growth trail. I agree with the moderate rating because of the elevation gain and the difficulty of navigating the trail. Roots and rocks can be a big problem if you don’t pay attention. The reward at the lake is well worth the effort. Beautiful even on a cloudy day! I had the trail and lake to myself today. I ran into 4 people on the way down. I will return to this trail in the summer I am sure it’s even more stunning!

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

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!

Hiked this in the height of WA's summer. Nook trail was a steep climb and a good workout. West Tiger 3 was moderate, but the view was very underwhelming. Overall a good workout, but I would not do again. My phone recorded closer to 6 miles total.

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!!

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

Left parking lot about 0830, got to mason lake about 10. Put on micro spikes somewhere near the lake and kept them on the rest of the hike until returning back down to that spot. Walked on rocks to cross stream and continue to the peak. I didn’t use poles but they seemed to help many people with the semi-rock scramble near the top. Had lunch at the peak and put on a bunch of layers. Got back to parking lot about 4pm. Remember sunset is 4:30pm now!! It was beautiful when I hiked but I’m sure there is more snow to come.

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)

Beautiful views of the Mountains. Some trees down over the path that are tricky to navigate. Really icy at the top and around the lake. The path around the lake isn’t an easy one, but worth the walk. Amazing pics!

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.

It was an easy hike... it got cold at the top. Enjoy the hike.

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.

Great trail and some good mushroom foraging here. Lots of fallen leaves now but a group ahead of us was still able to find a bunch of chanterelle mushrooms. This trail is easier on the moderate spectrum in terms of difficulty level, lots of trail runners here.

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.

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!

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

Went today in the rain, pretty good rainy day hike with a lot of tree coverage. However, there are lots of rocks/roots that get slippery. Several different streams to cross and a good bit of time walking through water, having waterproof boots is *highly* recommended. 2-3 cars when we arrived around 9:30, but was full as we left around 11:45. The gravel road had a lot more potholes than we expected, doable in a basic car, but going slow + dodging was definitely key.

Hiked Nov 3: NW Forest Pass needed, easy road terrain driving in, bathrooms at TH. Well-marked, slight incline/decline, trail was not slick, a few blow-downs, very very wet, sometimes feel as if you are walking through a waterfall while on the trail, although it was easy to navigate. Huge beautiful old growths and so many waterfalls, I lost count! Lake 22 was beautiful! Quite popular but not overcrowded. Can’t wait to come back in the Spring!

K and I did this one in the rain. The Falls look great. Per NOAA the Skykomish flow was over 35.2 KCFS. The trail is in good shape, not too much of a crowed.

Gorgeous views, especially on a clear fall day. It was pretty crowded on the trail, but we did go on a Sunday. Get there early if you can, the views are worth it! The lake is clear and worth the hike.

The rain has arrived. Trail was not really muddy or slippery, though the top was shrouded in clouds with zero views. Good exercise as usual. Tip for getting some view under such weather: at the UPPER talus loop trail junction take a detour onto talus loop trail. In about five minutes you will arrive at the talus pile. This is low enough that it can be below the clouds, but high enough to have a descent view.
