Little Si

An easy to moderate 5-mile day hike or scramble with 1,200 feet of elevation gain. The trail winds through second growth forest with plenty of rock faces and boulders. Consider including the Boulder Garden Loop Trail. Hikers are treated to a grand view of the Upper Snoqualmie Valley and North Bend. This trailhead also provides access to Meditation Rock, a good high-angle rescue training area.

getting there

Take Exit 32 off of I-90 near North Bend. Turn left, crossing over I-90, and follow 468th Ave NE to SE North Bend Way and turn left.  Turn right onto SE Mount Si Road and then left into the Litte Si/Exit 32 Parking Lot shortly after crossing the bridge across the Middle Fork Snoqualmie River.

on the trail

Little Si

Hike the Little Si Trail 2.1 miles and 1,076 feet of elevation gain from the parking lot.

meditation rock

Look for climber's trail on left hillside just before an old camp. Ascend through dirt, brush, rock, skirting small cliffs moving occasionally right until cliffed out. Head through trees on faint trail left along the wall. When the wall ends ends, ascend a small chimney (10 feet, good hand holds and foot holds but dicey when wet). At its top is small grassy ledge. Climb another short pitch a little more difficult than first (grassy and slippery with no holds). There is a good rest stop and views at top of this section. Then move right over rock slabs, gravel and brush following cliff wall closely. There is a lot of brief exposure between chimney and end of this section. After climbing through trees, the route becomes clear. Move left up through rock, then right up over good rock to summit.

boulder garden loop

A trail that forks right ~0.3 miles from the start of the Little Si Trail and leads to the Mount Si Old Trail and loops back to the the Little Si Trail. Done by itself, it is 2.5 miles and 900 feet of elevation gain. Done with the Little Si Trail, it adds ~1.5 miles and 600 feet of elevation gain.
