Little Si is the little sister to Mount Si. The trail is easier with less elevation, but the view from the top is just as breathtaking with views of Snoqualmie Valley and Rattlesnake Mountain. Please note that dogs are allowed off leash, it is best to keep your dog on the leash because of the heavy traffic on this trail. Please note that the trail is often covered in snow and difficult to trek through much of the year. Discover Pass is required.

Great early season conditioner. The trail is very steep in spots. The summit is nice because it is big enough you don’t have to worry about falling off of it! The main parking lot still had spots at 11:30 on a Tuesday. Love the flat section in the middle. Very peaceful and quiet.

Gorgeous hike! Exceeded my expectations. Went up this morning and lucked out with sunny skies and very few people on trail. Trail was muddy in some parts but mostly clear. Nice hike if you’ve only got a few hours to spare

Took us about 2 hour 20 minutes total. Was easy to buy a discovery pass over the phone for parking. The hike was pretty and peaceful despite there being plenty of others on the trail. Saw some cool slugs, pretty birds and lush vegetation.

Pretty muddy but well marked trail. Best to get there before 10 or after 11am for a spot in the main lot on a Sunday.

Beautiful hike. Be awake that the trail is very rocky in parts and as those parts are also steep, I was glad that I was wearing goods boots and carrying a hiking pole.

Got there around 10 AM on Sunday. Parking spots were still available in the overflow lot. Need a Discover Pass for parking. Dog-friendly trail. Wet and muddy, but not a difficult hike up. Great views when the fog clears. Moderate traffic, but everyone was friendly.

Did the Little Si trail including the Boulder garden trail which adds another 1.4 miles and 880 feet of elevation gain. The Boulder garden detour is ugly and not worth it unless you want to make the relatively easy little si hike a bit more difficult.
There’s a lot of slush and it is muddy as well, but overall a nice hike with good views at the top.

This is an amazing short hike that's also very close to Seattle. We started a little late and therefore, both parking and overflow parking were full. But if you wait a little, there are always some people who are going to leave. The trail is very beautiful and looks very natural/wild. The mosses make the trail way more pretty and greener. I'd highly recommend this trail if you want something short and pretty. At the Summit there are two different views. One is facing Mt. Si where you get to see the beautiful forest and valley between Mt. Si and Mt. Little Si. The other view is facing Rattlesnake and North Bend.
My AllTrails Recording says, 4.0 mi round trip and 1150 ft elevation gain.

Moderate is accurate. Took us approx 2.5 hrs round trip with a long rest at the peak. It's a good warm up hike for training. Lots of flat parts in the middle of the trail, in a lovely wooded area. Meant to hike Mt Si today but I forgot my hikers and did it in stability runners + poles without too much problem, even with all the mud after a rainy morning. Even with the clouds the views of the valley and the peaks were lovely.
Main parking was full by Sunday 9:30 am when we arrived, and overflow parking lot was full before noon when we left.

A nice early in the season hike to build up to the longer ones. Great views, enough elevation gain to feel like you can skip the gym for today. Only down side is you’ll probably never get it to yourself, but there’s a reason it’s a popular hike.

Saw some lost car keys today in the overflow of the overflow parking. Someone left them sitting on an fence post near the parallel parking on the gravel road. They were still there when we left...

Trail was great! The shady part in the middle is the best.

We arrived at 11:20am and found a parking spot in the overflow parking as someone was leaving. It was a gorgeous day with tons of people of all types on the trail. No snow, warm day, gorgeous view at the top. Including a half hour at the top for lunch and several stops for photos and watching rock climbers, we spent 3 hours on the trail.

Absolutely loved this hike. If you’re looking for a moderate, relatively short hike that has high payout in views; this is your guy. If you go slow it can become an extended hike but my friend and I made it up in an hour. Once you get to the top you can climb down on the other side to get a full 180° view. There is also lots to explore along the way! Little look out points and boulders to climb.

We went on Friday March 29th, 2019 got there at 9:45am and reached the summit at 10:50am. Not to crowded. No snow.

Loved it. Great hike with a rewarding view. Area at the top is small, so you will be resting pretty close to others if you go when busy. Lots of kids and dogs on the trail. Highly recommend if you’re looking for something obtainable in a couple hours or so.

Hiked this yesterday. Surprisingly saw very few other people on the trail. Trail was 99% clear of snow, though about halfway there is significant snow on either side of the trail. Trail is quite muddy in some spots. got there at 9:15a and there was plenty of parking, but when we returned about 11:45 the parking lot was full.

03/18/19Definitelly recomend this trail. I’ve been there yesterday and it was an amazing view! The trail is in very good condition - you don’t need chains or little spikes to go there! Just forget for discovery pass, so make sure If you have it. I bought it on-line

Great short hike close to the city. One needs the Discover Pass, we got to the trail at 8:30am and had to use the overflow parking sports. Hike is around 5mikes from the parking lot, it was steep and had some snow on some areas. The peak had a beautiful view.

Great short hike with a decent amount of elevation. The view from the summit was awesome.

Lower park of the trail had some snow pack, and it was slippery throughout. Easily traversed if you have poles (or better yet crampons). wouldn't recommend without poles until it gets a little dryer.

The road and trail were in good conditions even though the area received a good amount of snow. We had the whole trail to ourselves and the snow covered trees at the top were breathless! It’s a nice simple hike and was blessed to see a black tail deer in the forest.

Gorgeous day for a hike in the PNW. We started this one around 10:30 am. Plenty of parking in the overflow parking lot. Trail starts out completely bare but after about 10 minutes or so you start to see the compacted snow on the trail. BE CAREFUL. still pretty icy in a lot of spots. Saw a few people fall (including myself haha). Coming down was a little more sketchy in some spots but go slow and try to stay on the side of the path. It was a gorgeous view from the top but super windy and cold. Overall, great hike. Still would recommend Mount si if you are looking for a better view.

Great hike with beautiful views! we got to the parking lot a little after 830am and got the last spot in the main parking lot (Saturday). Most of the trail is still compact snow and can be slippery in some spots but still very doable without spikes or hiking poles. a few trees have fallen over the trail but are easy to get around or over. incline is pretty decent at the beginning and at the end but the middle is easy walking. will definitely add it to my quick nearby hike list!

Hard packed snow. Regular sneakers were fine. Nice moderate effort trail with no difficult sections.

originally was planning on mt si but the trail head parking was closed. so decided on little si. cool short trail. i would say about 90% of the trail has snow covering. mostly hard pack snow with some areas getting slushy. ii like using my micro spikes for these conditions but you can make it up with just regular hiking boots.

Go early to beat the crowds! There were people coming down at 8am that had gone up for sunrise hikes. this trail gets super busy, both parking lots were packed when we finished with no spots left, we had people ask if they could wait for our spots. But this is such a gorgeous hike and so worth it!!

Fun hike with some rocky areas. View at the top worth every step! At least three trial options with different lenth and difficulty. We will head back for sure.

A bit crowded for January but otherwise a great hike through mossy woods with a couple nice lookouts.

Our first time doing Little Si and it was great! Lots of people out today! Lots of fur babies (most on leash) and little babies too! By far the busiest trail we’ve ever done. My 9yo did the whole trail, with quite a few breaks;) mom needed them too! Beautiful views, interesting scenery! I clocked 5.7mi car to car and just over 1,500ft EG!
