Rock climbers use the first half of this trail to get to the rock faces on the east end of Little Si. Hikers use the full trail to sweep around the west end and climb the tall knob on the easier (though still a bit rocky) route. Like its big sibling, Mount Si, Little Si offers phenomenal views of the Upper Snoqualmie Valley after a nice hike through forests and over rocks. The trail is steep initially, then mellow, then steep again as it scrambles straight up the northern spine to the 1576-foot summit.

This area was logged extensively, but in the intervening decades the forest has regenerated nicely, and a diverse collection of evergreens and deciduous trees shade the trail.

As you near the hulk of rocky bluff known as Little Si, the trail levels off into a swampy area. Small streams link bogs filled with trillium and skunk cabbage. The trail is generally high and dry, though you will encounter an area of mud or three.

At around 1.5 miles, views open up onto the high, craggy rock of the southeastern face of Little Si. You might see rock climbers crawling up the rock routes here. Continue along the trail as it loops north and then west to the gentler north face of Little Si.

The trail turns and runs straight up this northern spine, climbing steeply up the rocky ridge--you'll be forced to use your hands at times as you scramble up the biggest rocks--until finally capping out on the 1576-foot summit on the southern edge of the rocky prominence. Enjoy stellar views of the North Bend valley before heading back the way you came.
Driving Directions:

From Seattle drive east on I-90 to exit 32 (436th Avenue SE). Turn left (north) over the freeway and drive 0.5 mile to North Bend Way. Turn left (west), and in 0.25 mile turn right (north) on Mount Si Road. Shortly after crossing the bridge, the road banks right. Just after this curve, look for a paved parking area on the left side of the road (if you get to the intersection with 444th Avenue SE, you've gone too far).

After doing Mailbox Peak on Saturday we decided to have an easy hike up Little Si. The weather was lovely. We got there early enough but we still had to park in the overflow lot. A lot of folks having the same idea as us.
 
This is our third time in the space of a year doing this trek. We decided to push it up the hill kind of in a hurry type of pace. Well at least where we could get around people. Last year we thought this trek was kind of a wee tough but now on the third trip up it is just a great little hike to pass away a bit o time. Better than walking around Greenlake like. We made it up in 47 minutes. Not so shabby for two old goats.

Overall a great hike for everyone.

We started the trail around 3pm and it took us 100 minutes to get to the summit. The initial incline is steep and there is a lot of flatland trekking after that. There were a few muddy patches on the way. No snow. We loved the meadows which was very pleasant and beautiful. The final incline was very exhausting but the final summit view is totally worth it & spectacular. We were back in the parking lot by 6 pm and there were still many people on their way up.

Well we started out intending to hike up to Little Si. With a couple missed turns we ended up on the Old Big Si Trail and ultimately ended up atop Mount Si. We left the Little Si trailhead (which was full) around 11:40 am. We arrived atop Mount Si at about 3:00 pm.

The Old Si trail is in good shape with a few muddy spots. It was steep and rather grueling at times but well worth it. At the top of Mount Si we were greeted by about 6-8 others and a couple dogs. The birds at the top are really aggressive if you have food out. We didn't attempt the Haystack this trip but since we were planning on doing Si in a couple of weeks anyways we figured we would give it a try then.

The trail is a little rough going down, hard on the toes and knees. If you are looking for a quiet trip up to Mount Si and don't mind a little more of a workout then this is a good route. We only passed 3 or 4 people the entire trip on the old Si trail. There is a little snow at the top of the trail and quite a bit on the summit just below the Haystack, nothing to be concerned about though.

Views from the top were amazing!

Went with a friend up this moderately difficult hike. It took us (we are both relatively out of shape) 3 hours approximately to reach the summit, have lunch, and make it back to the parking lot. Some rocky parts, but really beautiful through the thick forest. The top is a good payoff, the views are great from the top, and you can see the sea of trees going up the side of Little Si's big brother. It was really windy at the top though, and I needed gloves because my hands were so cold. Good hike!
