"Long overshadowed both literally and figuratively by its big brother next door, Little Si is a worthwhile destination on its own and offers a good alternative when its hulking neighbor is too busy, too socked in, or too demanding. Watching rock climbers on the lower cliffs is an interesting diversion along the way." Read more

"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." Read more

"Under the shadow of its bigger brother, Little Si is so tiny, so close. Whether you need a quickie in the forest after a hard day at the office or an interesting walk with young children, Little Si is a perfect fit. Its accessibility to Seattle makes it more of an urban walk than a wilderness hike, and this popularity is reflected by a wide and beaten down track and a thirty-car parking area with a lot of turnover—and not of the pastry kind. Nevertheless, this is still a very pretty route to take, and views from the top are just as good as from Mount Si—and much less work!" Read more

"Too many beginners with children take on the Mount Si Trail, which proves to be so difficult that the kids may never want to hike again. Overlooked is kid-size Little Si, also difficult but more realistic, offering children the challenge and satisfaction" Read more

Great hike, well maintained trail. Even though it is the little sister to the big Si, it was a good work out. Great hike for taking the baby in the carrier and taking out of town guests. Nice view at summit with some peeks on the way. Was cool watching the rock climbers too.

Lots of people; nice and reasonable ascent for young kids (5-10). I even saw a 3 year old climbing along the trail.

Beautiful views of the North Bend area and of the much larger Mount Si. Very popular and got quite annoying meeting tons of people and having to wait while they passed by on some narrow portions of the trail. Lots of families and people with pets, most of which were not on leashes. Fairly easy hike if you're short on time and want a nice view. Get out there early if you want a parking spot in either of the two main lots, otherwise it will fill up quick. Steep to start the hike, evens out for a while and finishes pretty steeply.

Hike was a great work out. There was some fun scrambing to do. Trails were well maintained but signs and markers need to be worked on if not added. Was well worth the hike. Make sure you show up early...before 10am. Parking lot fills up quick! for those Geocachers out there. There is one at the top!!

Trail was in great shape. I would recommend leaving early, as the parking lots fill up by about 10 am, and the trail will be inundated with people. Fairly relaxed hike, good for those who don't hike much or are new to the game.

My 2 boys and I just hiked the Boulder Garden Loop trail which branches off the Little Si trail. It's great. We will describe this in the second edition of the 60 Hikes Seattle book in Spring 2009.

This is a nice trail for kids. We took our 4 and 6 year olds up this trail. The down sides is that the trail is very crowded. To make matters worse, we went the on Labor Day holiday which added even more hikers. I've hiked this trail a couple of times and it is nice if you start early and avoid the crowds. Three miles round trip and about 1,500 elevation gain and a reasonable view at the top. BEWARE of car prowlers at the parking lot! I'm giving this 2 stars because of the crowds, but for kids I'd up that to 4 stars.
