Boulder Garden Loop Trail
Event Overview

We need your help to keep Washington trails and trailheads safe and accessible this fall!

Our work will include restoration and trail maintenance on the Boulder Garden Loop Trail, a lovely trail that intersects with both the popular Little Si trail and the Old Si trail. We will do a variety of basic trail maintenance tasks--improving the tread surface, installing and maintaining drains, and cutting back brush. We may also restore impacted areas along the trail or remove non-native plants that are growing along the trail.

Difficulty
Moderate to Strenuous
Age Restriction
Ages 14 and up.
What to Bring

For safety, volunteers are required to wear:

  • Long pants (we’ll be working with tools, so no shorts!)
  • Sturdy, close-toed shoes (absolutely no sandals)
  • Gloves

In addition, we recommend that participants bring:

  • Warm layers, especially during the fall, winter, and spring
  • Rain gear
  • Big sack lunch
  • Water for the day (3 liters minimum)
  • Small daypack for lunch, extra layers, etc.
Driving Directions

We will park in the Little Si Overflow Parking Lot: https://goo.gl/maps/KHkJ6WpiYEE2

From Seattle, take exit 32 from I-90 E for 436th Ave SE. Turn left on 436th Ave SE and go 0.6 miles, then turn left onto SE North Bend Way. In 0.3 miles, turn right onto Mt. Si Rd. In about half mile, the Little Si Overflow Parking Lot will be on your left. Look for Greenway signs, staff, and vehicles.

Additional Information
Companion piece to neighbor and big brother Mount Si, the small rocky bluff known as Little Si is a moderately graded round trip 4.7 mile trail located in the hike rich North Bend area. Little Si is an important site in the Snoqualmie Tribe’s oral history of the Snoqualmie Valley. The Boulder Garden Loop Trail meanders through moss covered boulders inspiring poetic reflection and provides a scenic detour on the route up Little Si.
