This somewhat easy 4.4 mile hike attracts all types of hikers and is very family friendly. The travel time from Seattle to Little Si is about 30 minutes. There is a good sized parking lot at the trailhead where you will find the only restrooms — plus an overflow lot. This is a very popular hike so be prepared to arrive early on weekends to avoid the crowds and get a parking spot. This is a great sampler of Cascade hiking.
The trail is steep initially, then mellow, then steep again as it scrambles straight up the northern spine to the 1576-foot summit. When you get towards the end of the trail you will sweep around the west end of Little Si 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.
- Round trip: 5 miles
- Elevation gain is 1200 feet. This is a family friendly hike and you will see many children of all ages
- Outstanding features are the mountain and valley views at the end of the trail

Little Si Natural Area borders the Mount Si NRCA on its north and eastern boundaries, the Middle Fork of the Snoqualmie River on its western boundary and private property on its southern boundary.

Approximately 90% of the natural area is composed of a homogenous second growth conifer stand.
