Meet at 9:30 AM at the Starbucks at 1436 Auburn Way S., Auburn, reached by taking the Auburn Way S. exit from SR 18 and heading south on Auburn Way S.  It is inside the V where M Street meets Auburn Way S.

From the Starbucks we will caravan to the trailhead, heading south on Auburn Way S, which becomes SR 164 (Auburn-Enumclaw Highway) eastbound,  turning left at SE 38th PL, right at 160th Pl SE, which becomes SE 384th St and left at 188th Ave SE, parking along the road near the trailhead at SE 370th St.

The hike will meander through a scenic wilderness area, arriving around Noon at a picnic table overlooking the Green River, where we have our lunch.  After lunch we will hike to a spawning area on the river and return to the lunch spot and a loop trail back to the trailhead.   There is a restroom at Starbuck's and a portapotty at the lunch spot, but no restroom facility elsewhere on the hike.  The hike is almost entirely under a forest canopy and there will be opportunities for party separation bathroom breaks at numerous trail junctions along the hiking route.
