Meet at 10:30 AM at the trailhead parking lot on Mt. Si Road, reached by taking Exit 32 from I-90, turning left at the end of the exit, left at the T junction and right on Mt. Si Road.  You pass the overflow parking lot before reaching the main Little Si parking lot.  It has a restroom by the trailhead, where we will meet.  If the main parking lot is full, park in the overflow lot and walk the trail to the main parking lot.  Each car must display a Discover Pass, which is different from the Northwest Forest Pass and the National Park passes. 

The trail climbs steeply the first half mile, runs more level the next mile and then steeply again the last half mile.  We'll have our lunch at the summit, where we sit on terraced rock with a commanding view of the valley below.  We'll be hiking under a forest canopy until we reach the lunch spot, where we will be in the open.
