Meet at 9 AM at the Starbuck's at the corner of Auburn Way S. and M Street in Auburn.

We will caravan from the Starbucks meeting place to the trailhead on 188th Ave SE, near SE 370th St.  No parking pass is required.  Restroom facilities are available at the Starbucks meeting place and at the lunch spot, but not at the trailhead.  Carpooling before reaching the meeting place is advised because of not being able to leave cars at Starbucks and limited parking space near the trailhead. The Green River Nature Preserve is the result of combining three existing parks via connecting land recently acquired by King County.  Efforts are underway to, over time, replace the existing deciduous forest with a native evergreen forest, restoring the park to the way it was before logging occurred.   Additional information is available on the WTA web site.
