Meet at 9 AM at the Enumclaw Ranger Station, 450 Roosevelt Ave E (SR 410), Enumclaw.  No parking pass is required there.  

From the Enumclaw Ranger Station, we will caravan to the Crystal Lakes trailhead on SR 410, leaving half our cars there, where no parking pass is required,  and driving in the other cars to the  PCT trailhead just east of Chinook Pass.  Cars parked there  must display either the Northwest Forest Pass or National Park Pass.  There are four restrooms there.

Our hike will start north on the PCT, with a lunch stop and possible swim at Sheep Lake.  After lunch, we will continue north on the PCT to Sourdough Gap, where we still stop for a rest stop and pictures.  Then we will continue over Bear Gap to a viewpoint overlooking Upper Crystal Lake, which is another picture opportunity.  Then we hike down to Upper Crystal Lake for a rest break and possible swim.  Then we continue down to Lower Crystal Lake for pictures and to use the restrooms there.  Finally we descend to SR 410, where we get into the cars left there for the return drive to Chinook Pass and to our original cars.  On the drive home, there is the option for a meal stop at the Naches Tavern in Greenwater.  This hike tends to end late in the afternoon, so those registering for it should not plan early evening activities.  Carpooling will need to accommodate the car shuttle.
