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).

Hiked with an out of town friend and my dog today on a very wet trail! Saw a group of upper middle aged ladies getting out there and enjoying the trail system, a lone man, a family of four with two small kids and two teenage girls. Love a light day on this trail which can easily see hundreds on a beautiful weekend day.

Despite wet conditions clouds briefly cleared allowing patchy views of Mt Si and the town below. One of my favorite hikes on a light day!

Had a great day on the trail along with lots of other nice folks. We got a late start and the parking lots were full so we parked at the City Park and hike the Snoqualmie Trial to the trail head.

No problems on the trail and the sun was out by the time we reached the summit. It was a little crowded on top but we did get a few pictures and then headed back down. On the way back we took a little time to watch the people climbing the rock face and enjoy the valley at that point of the trail.

Lots of people with dogs and most we well behaved. Not a lot of flowers but we did see one Trillium and got a few pictures of the ferns and moss.

This is a trail of many characteristics and it is always a pleasure to experience them all. If you are here for the moss, there couldn't be better display along with the boulders and the impressive rock wall that goes straight up from the forest floor at about the half way mark. And then you get the open view on the rock summit down the valley, Rattlesnake Ridge, Mt Si Mt Washington and other peaks.

The trail is in good condition but that last near scramble of roots and rocks below the top reminds you that you are on a mountain. We arrived at the summit at about 1130 and after a couple groups left we had the rock to ourselves, but on our way down we met dozens of hikers heading up along with lots of dogs. Hope they all had room up there, and this was on a Wednesday.

We saw our first trillium of the year along the trail and also the first couple mosquitoes.

Both parking lots were mostly full when we reached the trail-head around 1:00 PM on this foggy, overcast Sunday.

The initial ascend was steep but leveled off a bit after that. The trail makes its way through second growth forest with moss covered rocks and ferns that were simply stunning. Birds were singing and wild flowers were starting to bloom along the trail. Also, saw some rock climbers on the eastern walls. After meandering a bit, the trail starts to climb steeply up the rocky ridge. Had to use hands in certain places to get up the rocks.

Visibility was limited at the top with fog and low clouds. Was drizzling a bit up there. Not a lot of people at the summit. After spending some time enjoying the scenery, we started our descent. Because of recent rains and the huge boulders, the initial descend was a little slippery and challenging. Watch your step!

Overall, a beautiful and nice hike with fairly wide and well maintained trail.

First Hike for my husband and I, and our puppy. Was a very rainy day, but we were protected much of the time by the trees. Not too crowded, and we could easily let others pass anywhere along the trail. Had to use hands at times to climb the steep, rocky, path. Well maintained trail.
