Meet at 8 AM at the Preston Park and Ride lot, reached by taking Exit 22 from I-90 and turning left at the end of the exit and left again at the T junction to find the P & R lot on your left.

We will consolidate cars at the Park and Ride lot.  There are restrooms and a Subway at the strip mall to the east.   From the P & R lot, we will caravan to the trailhead, east of Snoqualmie Pass.  The leader will provide driving directions at the meeting place.

Our short hike will take us by both Cottonwood and Mirror Lakes, providing us swimming opportunities at both, and we will pass numerous huckleberry bushes at the height of their season, so time will be allow for picking berries also.  Our lunch and turnaround spot will be at Mirror Lake.  A Northwest Forest Pass or National Park Pass must be displayed by each car parked at the trailhead.
