Meet at the "school bus turn around" at 9:00am

From I-90, take exit 32 (436th Avenue SE). Turn left (north) over the freeway and drive 0.5 miles to SE North Bend Way. Turn left (west), and in 0.25 mile turn right (north) on SE Mt Si Road. In approximately 3.5 miles (past the Little Si and Mt Si trailheads), you will reach a small parking area on the left (directly across from 480th Ave). This is known as the school bus turnaround, and, if you are parking here on school days, park close to the gate. The trailhead is unsigned except for a notice that a Discover Pass is required to park here.

Do a day of stewardship with King County's Weed Watcher's Program! On this hike you will learn how to identify invasive weeds, use surveying equipment, remove weeds, and hike with friendly, like-minded people.

This activity is through the King County Weed Watchers program.
