Fantastic view on top. Except the last mile, the rest is moderate.

Was a beautiful and moderate to hard hike. Definitely a little more challenging but not that bad if you’re a usual hiker. Went with 2 people that don’t usually hike from Texas and they had a little bit of a hard time but did it with breaks in between. There’s absolutely no snow at the top, so don’t believe that. Micro spikes would be completely pointless. Beautiful view at the top, but really doesn’t open up until you’re at the top. Worth it.

Mt Si was a brutal beast yesterday 4/21. So much beauty at the top. My health tracker documented 10 miles. No snow on the ground. Great training hike for Mt St Helens. Will be back!

Great moderate hike. Went 2 months ago and brought my 7&9year old. Just watch them at the top! Beautiful scenery!

Was there yesterday, beautiful hike! No need for spikes, very light snow cover at the top but very manageable in sneakers or boots. Perfect day hike to celebrate earth day!

Left yesterday at 1:30pm. Hiked up the logging road and skipped the falls. Hit snow at about the last switchback with elevation gain. At the connector trail to Si we put on micro spikes which I think improve conditions. Made our way to the top. Maybe 1/2 mike to 3/4 miles from the top the trail disappeared and we post holed to the top. Great views. Made our way back down to truck and got it at 7:30pm. 6 hours total.

Hiked on Thursday. First of all BEAUTIFUL trail and everyone is so nice and there were so many dogs ON LEASHES TOO! It’s a toughy for me at least and my back started giving my trouble at 3.5miles but I knew I had to keep going. Brought my spikes but didn’t use them for the last bit, just took it nice and slow. I’ll be back

Did it back in December and the views were worth the climb up. Very moderate.

Loved it. Easy for the most part - the last mile or so there is moderate climbing but nothing too strenuous. Waterfall itself is definitely worth the hike.

Not easy one, be prepared and wear hiking boots, we saw many people on sneakers, probably their hiking wasn’t so enjoyable not wearing properly shoes. It’s very pretty and the waterfall is worth the hike.

Way to many people but a decent hike

Sooooo much fun. still needed micro-spikes for the last mile in the snow and ice. Simply gorgeous. The old growth Douglas fir trees are beautiful neat the mid-way point.

I did this hike a year ago and it was a good one. Beautiful, challenging and well kept. There seems to be snow into spring so dress accordingly, I had to learn the hard way with this hike but it was well worth it! Make sure you are in good shape to finish this hike so you can finish it in a timely manner!

Beautiful! Lots of snow at the top today. Glad I brought my spikes.

Light rain the whole time. Well marked trail, friendly folks and close enough to the city to get an aggressive training hike.

A great challenge and beautiful view! I did not need crampons at the top after Monday’s sunny day it was mostly melted and slushy.

My wife and I hiked to Mount Si with our hiking group. We went up Old Mt. Si Trail and came down the new trail and traversed via Douglas Fir Trail. By taking the new trail down we made it easy for our knees. The weather was mostly sunny. The temperature was 51 F when we started at the trailhead and 43 F at our lunch spot and 66 F when we got back to the trailhead. There was some snow near the summit. The view at our lunch spot on the rocks was pretty good, but Mount Rainier was hidden in clouds.

Awesome hike! We had a pretty warm day yesterday and a lot of the snow melted at the top. I put my spikes on to walk 20 feet then took them off. Stay on the pinestraw and you're all set, the spikes were over kill IMO.

Good relatively easy hike. Quiet compared to Mt Si trail. Cool birds.

Loved it!

A little wet & muddy road, but I like it.

Beautiful hike. Must bring crampons during this time of year to get to the top.

Steady gain in elevation. Perfect if you’re looking for a low-key morning workout. Hiking boots, poles, and crampons are a must if you want to make it to the top. The snow pack gets pretty slick as you get higher up!

Great hike, great view. Good evaluation and length but a little busy in weekend.

Wife and I did this trail this morning and had a great time. The parking lot was fairly full but the trail was never close to being anywhere near crowded. The weather was just right with it only being a bit cool towards the top. I was hesitant at first about bringing crampons but certainly glad I did. I got a kick out of watching all those in sneakers skidding and sliding around trying to not fall on their butt or worse off the trail. Overall it was a fun hike and would recommend it.

On March 10th a Friend and I climbed to the top of Mount Si. Here is a video i made along the way: https://www.youtube.com/watch?v=u0tvffyzSH8&t=3s We began hiking at 6:00am from the main trailhead, it was 29 degrees, clear skies and only a few cars in the parking lot. About 2ish miles up the trails we stopped and i put on my crampons, microspikes would have also worked a little while later we made it to the top of Mount Si through a near vertical scramble. I would only attempt this if you have crampons or an ice axe as it was a little hairy!! The cornices at the top weren't terrible but still stay away from the edge. We stayed at the top for a little bit took a few photos and then began working our way back down the views were incredible, not a cloud in the sky only a little windy. On the way down we encountered a TON of people we couldn't hike for more than one minute without seeing another group of people headed up the trail. We reached the trailhead around 11:00 and it was full. Again here is the video i took on the hike: https://www.youtube.com/watch?v=u0tvffyzSH8&t=3s

Be safe out there,

This hike is awesome! Right now it starts to get icy just before the falls. The falls were partially frozen when I was there. After the falls it gets very steep. You have probably 20-30 mins of a rocky terrain and after that it's all powdered snow until the top. Fantastic views from the top. Be careful of the cornice at the top. The hike down was a nice change of scenery from the hike up but it felt like it dragged on forever. All around a great hike! Will do it again!
